principal element of our business strategy consists of upgrading our facilities within our Treatment Segment to increase efficiency and
modernize and expand treatment capabilities to meet the changing markets associated with the waste management industry. Within our Services
Segment, we continue to bid on projects, increase competitive procurement effectiveness and broaden the market penetration within both
the commercial and government sectors. The Company continues to remain focused on expansion into both commercial and international markets
to supplement government spending in the United States of America (&#8220;USA&#8221;), from which a significant portion of the Company&#8217;s
revenue is derived. This includes new services, new customers and increased market share in our current markets.</span></p>

2022 financial results continued to be impacted by COVID-19, among other things. Our Treatment Segment began to see steady improvements
in waste receipts starting in the second quarter of 2022 from certain customers who had previously delayed waste shipments due, in part,
from the impact of COVID-19. This positive trend was negatively impacted by occurrences of severe weather conditions which resulted in
temporary delays in waste shipments from certain customers and a temporary shortage in skilled production personnel which peaked through
the fourth quarter of 2022 at one of our facilities. In early part of 2022, our Services Segment continued to experience delays/curtailments
in project work by certain customers since the award of projects to us late in the second quarter of 2021 due to COVID-19 impact and/or
administrative delays. However, starting in the second quarter of 2022, work under these projects had resumed/increased as the pandemic
impacts began to subside and has since reached full operational status. In 2022, we continued to realize delays in procurement and planning
on behalf of our government clients that saw easing through the second half of the year. Heading into 2023, we expect to see continued
improvements in waste receipts and continued increases in project work from contracts recently won and bids submitted in both segments
that are awaiting awards, subject to potential COVID-19 and economic impacts. (See &#8220;Item 7. Management&#8217;s Discussion and Analysis

percent and our interest will be forty-five (45) percent. The finalization, form and capitalization of this unpopulated partnership is
subject to numerous conditions, including but not limited to, winning a certain contract, completion and execution of a definitive agreement

treatment/disposal capabilities for low level radioactive waste in Andrews, TX, is also a competitor in the treatment market with increasing
market share. These two competitors also provide us with options for disposal of our treated nuclear waste. The Treatment Segment treats

Services Segment is engaged in highly competitive businesses in which a number of our government contracts and some of our commercial
contracts are awarded through competitive bidding processes. The extent of such competition varies according to the industries and markets
in which our customers operate as well as the geographic areas in which we operate. The degree and type of competition we face is also
often influenced by the project specification being bid on and the different specialty skill sets of each bidder for which our Services
Segment competes, especially projects subject to the governmental bid process. We also have the ability to prime federal government small
business procurements (small business set asides). Based on past experience, we believe that large businesses are more willing to team
with small businesses in order to be part of these often-substantial procurements. There are a number of qualified small businesses in
our market that will provide intense competition that may provide a challenge to our ability to maintain strong growth rates and acceptable
profit margins. For international business there are additional competitors, many from within the country the work is to be performed,
making winning work in foreign countries more challenging. If our Services Segment is unable to meet these competitive challenges, it
could lose market share and experience an overall reduction in its profits.</span></p>

health threats and outbreaks such as COVID-19 and natural disasters such as hurricanes and severe weather conditions have negatively
impacted our results of operations. The direct impacts of these such events resulted in delayed waste shipments from certain of our customers

costs which could have a downward effect on our business, financial condition and results of operations. We may attempt to increase our
sales prices in order to maintain satisfactory margin; however, competitive pressures in our industry may have the effect of inhibiting
our ability to reflect these increased costs in the prices of our services that we provide to our customers and therefore reduce our
profitability.</span></p>

have sufficient liquidity to repay our debt under our credit facility and other indebtedness and/or operate our business.</span></p>

December 31, 2022, our aggregate consolidated debt was approximately $1,039,000. Our Second Amended and Restated Revolving Credit, Term
Loan and Security Agreement dated May 8, 2020, as amended, provides for a total credit facility commitment consisting of a $18,000,000
revolving line of credit, a term loan balance of approximately $1,742,000 and a capital line of $1,000,000, with advances available through
May 4, 2022. As a result of a recent amendment to our credit facility that we entered into with our lender in March 2023, the revolving
line of credit was reduced to $12,500,000. The maximum we can borrow under the revolving part of the credit facility is based on a percentage
of the amount of our eligible receivables outstanding at any one time reduced by outstanding standby letters of credit and any borrowing
reduction that our lender has or may impose from time to time. At December 31, 2022, we had no borrowing under the revolving part of
our credit facility and borrowing availability of up to an additional $4,290,000. The borrowing availability of $4,290,000 at December
31, 2022 included a requirement from our lender that we maintain a minimum of $3,000,000 in borrowing availability. As a result of the
amendment to our credit facility that we entered into with our lender as discussed above, we are required to continue to maintain a minimum
of $3,000,000 in borrowing availability under the revolving credit until the minimum FCCR requirement for the quarter ended June 30,
2023 has been met and certified to our lender. A lack of positive operating results could have material adverse consequences on our ability
to operate our business. Our ability to make principal and interest payments, to refinance indebtedness, and borrow under our credit
facility will depend on both our and our subsidiaries&#8217; future operating performance and cash flow. Prevailing economic conditions,
interest rate levels, and financial, competitive, business, and other factors affect us. Many of these factors are beyond our control,
including the impact of COVID-19.</span></p>

the disruption of our business operations. A security breach could adversely impact our customer relationships, reputation and operation
and result in violations of applicable privacy and other laws, financial loss to us or to our customers or to our employees, and litigation
exposure. While we maintain a system of internal controls and procedures, any breach, attack, or failure as discussed above could have

change is receiving ever increasing attention from scientists, legislators and the public. The debate is ongoing as to the extent to
which our climate is changing, the potential causes of this change and its potential impacts. Some attribute global warming to increased
levels of greenhouse gases, including carbon dioxide, which has led to significant legislative and regulatory efforts to limit greenhouse
gas emissions. Presently there are no federally mandated greenhouse gas reduction requirements in the United States. However, there are
a number of legislative and regulatory proposals to address greenhouse gas emissions, which are in various phases of discussion or implementation.
The outcome of federal and state actions to address global climate change could result in a variety of regulatory programs including
potential new regulations. Any adoption by federal or state governments mandating a substantial reduction in greenhouse gas emissions
could increase costs associated with our operations. Until the timing, scope and extent of any future regulation becomes known, we cannot
predict the effect on our financial position, operating results and cash flows.</span></p>

effective internal control over financial reporting is necessary for us to produce reliable financial reports and is important in helping
to prevent financial fraud. If we are unable to maintain adequate internal controls, our business and operating results could be harmed.
We are required to satisfy the requirements of Section 404 of Sarbanes Oxley and the related rules of the Commission, which require,
among other things, management to assess annually the effectiveness of our internal control over financial reporting. For the year ended
December 31, 2021, management concluded that a material weakness existed in internal control over financial reporting related to our
application of ASC 606, &#8220;Revenue from Contracts with Customers,&#8221; specifically to contracts that contain nonstandard terms
and conditions. This material weakness has been remediated (see &#8220;Item 9A. Controls and Procedures&#8221; for a discussion of this
material weakness and the remediation plan that were implemented). If we are unable to maintain adequate internal control over financial
reporting at any time going forward, there is a reasonable possibility that a misstatement of our annual or interim financial statements
will not be prevented or detected in a timely manner. If we cannot produce reliable financial reports, investors could lose confidence
in our reported financial information, the market price of our common stock could decline significantly, and our business, financial
condition, and reputation could be harmed.</span></p>

choose not to invest in us, or otherwise do business with us, if they believe our policies relating to corporate responsibility are inadequate
or do not align with theirs. Third party providers of corporate responsibility ratings and reports on companies have increased in number,
resulting in varied standards. In addition, the criteria by which companies&#8217; corporate responsibility practices are assessed are
evolving, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new criteria.
Alternatively, if we elect not to or are unable to satisfy such new criteria or do not meet the criteria of a specific third-party provider,
some investors may conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational damage
in the event that our corporate responsibility procedures or standards do not meet the standards set by various constituencies. If we
fail to satisfy the expectations of investors, our customers and other stakeholders or our initiatives are not executed as planned, our
reputation and financial results could be adversely affected and our revenues, results of operations and ability to grow our business
may be negatively impacted. Additionally, new legislative or regulatory initiatives related to ESG could adversely affect our business.</span></p>

impacted by occurrences of severe weather conditions which contributed to temporary delays in waste shipments from certain customers
and a temporary shortage in skilled production personnel which peaked through the fourth quarter of 2022 at one of our facilities. In
early part of 2022, our Services Segment continued to experience delays/curtailments in project work by certain customers since the award
of projects to us late in the second quarter of 2021 due to COVID-19 impact and/or administrative delays. However, starting in the second
quarter of 2022, work under these projects had resumed/increased as the pandemic impacts began to subside and has since reached full
operational status.</span></p>

believe we have sufficient liquidity on hand to continue business operations during the next twelve months. At December 31, 2022, we
had borrowing availability under our revolving credit facility of approximately $4,290,000 which was based on a percentage of eligible
receivables and subject to certain reserves. Our borrowing availability of $4,290,000 at December 31, 2022 included a requirement from
our lender that we maintain a minimum of $3,000,000 in borrowing availability. As a result of an amendment to our Loan Agreement that
we entered into with our lender in March 2023, we are required to continue to maintain a minimum of $3,000,000 in borrowing availability
under our revolving credit until the minimum FCCR requirement for the quarter ended June 30, 2023 has been met and certified to our lender
(see &#8220;Financing Activities&#8221; within this MD&amp;A for a discussion of this amendment). We continue to assess ways to improve
our liquidity and the need in reducing operating costs during this volatile time. Reducing operating costs may include curtailing certain
capital expenditures and eliminating non-essential expenditures. We continue to closely monitor any potential impact from the countries&#8217;
economic conditions and COVID-19 pandemic on all aspects of our business. </span></p>

liquidity by either amending our existing lines of credit, obtaining new term loans or entering into equity transactions. There are no

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Revenue
decreased by $1,592,000 or 2.2% to $70,599,000 for the twelve-month ended December 31, 2022 from $72,191,000 for the corresponding period
of 2021. The decrease was entirely within our Services Segment where revenue decreased by $1,958,000 or 5.0% to $37,241,000 from $39,199,000.
As previously disclosed, work under certain of the new projects awarded to our Services Segment at the end of the second quarter of 2021
continued to be delayed/curtailed into most of the first quarter of 2022 due to COVID-19 impact and/or administrative delays experienced
by certain customers. However, work under these projects resumed/increased starting in the second quarter of 2022 and has since reached
full operational status. The lower revenue in 2022 was further exacerbated by the completion of a large project in the second quarter
of 2021 which was not replaced with a similar size contract because of delays in contract awards and procurement from COVID-19 impact
which continued into the first half of 2022 and eased through the second half of 2022. Our Treatment Segment revenue increased by $366,000
or 1.1% primarily due to overall higher waste volume which was offset by lower averaged price waste due to revenue mix. As disclosed
above, our Treatment Segment began to see steady improvements in waste receipts starting in the second quarter of 2022 from certain customers
who had previously delayed waste shipments due, in part, from the impact of COVID-19. This positive trend was negatively impacted by
occurrences of severe weather conditions which resulted in temporary delays in waste shipments from certain customers and a temporary
shortage in skilled production personnel which peaked through the fourth quarter of 2022 at one of our facilities.</span></p>

gross profit for 2022 increased $2,785,000 or 40.8%. The increase was entirely from our Services Segment due to higher margin projects.
The decrease in Treatment Segment gross profit was impacted by overall lower averaged price waste from revenue mix and the impact of
the increase in fixed costs. SG&amp;A expenses increased by approximately $1,807,000 or 14.1% for the year ended December 31, 2022 as
compared to the corresponding period of 2021.</span></p>

Treatment and Services Segments&#8217; business continues to be heavily dependent on services that we provide to governmental clients,
primarily as subcontractors for others who are prime contractors to government entities or directly as the prime contractor. We believe
demand for our services will continue to be subject to fluctuations due to a variety of factors beyond our control, including, without
limitation, the economic conditions, the manner in which the applicable government will be required to spend funding to remediate various
sites, and/or potential further impact from COVID-19. In addition, our governmental contracts and subcontracts relating to activities
at governmental sites in the United States are generally subject to termination for convenience at any time at the government&#8217;s
option, and our governmental contracts/TOAs with the Canadian government authorities also allow the authorities to terminate the contract/task
orders at any time for convenience. Work under all of our contracts/TOAs with Canadian government authorities has substantially been
completed. A significant account receivable due to PF Canada is subject to continuing negotiations. See &#8220;Known Trends and Uncertainties

Segment revenue increased by $366,000 or 1.1% for the twelve months ended December 31, 2022 over the same period in 2021. The overall
increase was primarily due to higher waste volume as certain customers who had previously delayed waste shipments due to COVID-19 resumed
steady waste shipments starting in the latter part of the second quarter. This positive trend was negatively impacted by occurrences
of severe weather conditions which resulted in temporary delays in waste shipments from certain customers and a temporary shortage in
skilled production personnel which peaked through the fourth quarter of 2022 at one of our facilities. The higher revenue from higher
waste volume was offset by lower averaged price waste from revenue mix. Services Segment revenue decreased by approximately $1,958,000
or 5.0%. As previously disclosed, work under certain of the new projects awarded to our Services Segment at the end of the second quarter
of 2021 continued to be delayed/curtailed into most of the first quarter of 2022 due to COVID-19 impact and/or administrative delays
experienced by certain customers. However, since the second quarter of 2022, work under these projects had resumed/increased and has
since reached full operational status. The lower revenue in 2022 was further exacerbated by the completion of a large project in the
second quarter of 2021 which was not replaced with a similar size contract because of delays in contract awards and procurement from
COVID-19. Our Services Segment revenues are project based; as such, the scope, duration and completion of each project vary. As a result,
our Services Segment revenues are subject to differences relating to timing and project value. In 2022, our Segments continued to realize
delays in procurement and planning on behalf of our government clients which did not ease until the second half of 2022.</span></p>

overall fixed costs were higher by approximately $1,234,000 resulting from the following: general expenses were higher by $483,000 primarily
due to higher utility costs; depreciation expenses were higher by approximately $392,000 due to depreciation for asset retirement obligations
in connection with our EWOC facility; regulatory expenses were higher by approximately $232,000 primarily due to additional closure costs
recorded for our EWOC facility due to change in estimated costs; maintenance costs were higher by approximately $109,000; salaries and
payroll related expenses were higher by $61,000; and travel expenses were lower by approximately $43,000. Services Segment cost of goods
sold decreased $6,218,000 or 15.9% primarily due to lower revenue. The decrease in cost of goods sold was primarily due to lower salaries/payroll

Segment gross profit decreased by $1,475,000 or approximately 22.0% and gross margin decreased to 15.7% from 20.4% primarily due to lower

SG&amp;A expenses were higher primarily due to the following: overall outside services expenses were higher by approximately $654,000
resulting from higher consulting/outside services/audit fees; travel expenses were higher by approximately $19,000; general expenses
were higher by approximately $13,000 in various categories; and salaries and payroll related expenses were higher by approximately $445,000
primarily due to higher stock-based compensation expenses from options granted to certain employees in October 2021 and higher 401(k)
plan matching expenses as our payroll expenses in 2021 included more forfeitures of 401(k) plan matching funds contributed by us for
former employees who failed to meet the 401(k) plan vesting requirements. Additionally, Administrative salaries and payroll related expenses
were higher as in 2021, resources were allocated in supporting Medical Segment&#8217;s R&amp;D/administrative functions. Treatment Segment
SG&amp;A expenses were higher primarily due to the following: outside services expense were higher by $120,000 due to more consulting/business
matters (including our ESG initiatives); salaries and payroll related expenses were higher by $46,000; travel expenses were higher by
approximately $59,000; and general expenses were higher by $164,000 which included higher tradeshow expenses and various other categories.
The increase in SG&amp;A expenses within our Services Segment was primarily due to the following: travel expenses were higher by $32,000;
general expenses were higher by approximately $107,000 which included higher tradeshow expenses and various other categories; salaries/payroll
related and consulting expenses were higher by approximately $202,000, and credit loss expense on accounts receivable was lower by approximately
$54,000. Included in SG&amp;A expenses is depreciation and amortization expense of $82,000 and $33,000 for the twelve months ended December
31, 2022 and 2021, respectively.</span></p>

of 2021 included interest accrued for our Paycheck Protection Program (&#8220;PPP&#8221;) Loan which was forgiven by the U.S. Small Business
Administration (&#8220;SBA&#8221;) effective June 15, 2021. The overall lower interest expense was offset by monthly interest incurred
starting in June of 2022 from the capital line under our credit facility.</span></p>

had income tax benefits of $378,000 and $3,890,000 for continuing operations for the twelve months ended December 31, 2022 and 2021,
respectively. Our effective tax rates were approximately 10.5% and 139.0% for the twelve months ended December 31, 2022 and 2021, respectively.
Our effective tax rates for the twelve months ended December 31, 2022 were impacted by non-deductible expenses and state taxes. Our effective
tax rate for the twelve months ended December 31, 2021 was substantially impacted by the release of our valuation allowance on deferred
tax assets primarily related to U.S. Federal income taxes during the third quarter of 2021 of approximately $2,351,000. For the twelve
months ended December 31, 2021, the primary reasons for the differences between our effective tax rate and statutory tax rate were due
to the release of valuation allowance and the forgiveness of our PPP Loan which was included in our Consolidated Statement of Operations
as &#8220;Gain on extinguishment of debt&#8221; but is exempt from income taxes.</span></p>

Treatment Segment maintains a backlog of stored waste, which represents waste that has not been processed. The backlog is principally
a result of the timing and complexity of the waste being brought into the facilities and the selling price per container. At December
31, 2022, our Treatment Segment had a backlog of approximately $9,156,000, as compared to approximately $7,129,000 at December 31, 2021.
Additionally, the time it takes to process waste from the time it arrives may increase due to the types and complexities of the waste
we are currently receiving. We typically process our backlog during periods of low waste receipts, which historically has been in the
first or fourth quarters.</span></p>

Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended the ERC availability and guidelines under the
CARES Act. Following these amendments, we determined that we were eligible for the ERC, and as a result of the foregoing legislations,
are eligible to claim a refundable tax credit against our share of certain payroll taxes equal to 70% of the qualified wages paid to
employees between July 1, 2021 and September 30, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021
for a maximum allowable ERC per employee of $7,000 per calendar quarter in 2021. For purposes of the amended ERC, an eligible employer
is defined as having experienced a significant (20% or more) decline in gross receipts during one or more of the first three 2021 calendar
quarters when compared to 2019.</span></p>

intangible assets are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business
environment indicate that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, we perform
a quantitative test to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the
asset over its fair value. Significant judgments are inherent in these analyses and include assumptions for, among other factors, forecasted
revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long-term
discount rates.</span></p>

future cash flow assumptions and conclusions with respect to asset impairments could be impacted by changes arising from (i) a sustained
period of economic and industrial slowdowns (ii) inability to scale our operations and implement cost reduction efforts during reduced
demand and/or (iii) a significant decline in our share price for a sustained period of time. These factors, among others, could significantly
impact the impairment analysis and may result in future asset impairment charges that, if incurred, could have a material adverse effect
on our financial condition and results of operations. <span style="background-color: white">We believe that the assumptions and estimates

Closure Costs and Asset Retirement Obligations (&#8220;ARO&#8221;).</i> Accrued closure costs represent our estimated environmental liability
to clean up our facilities as required by our permits, in the event of closure. ASC 410, &#8220;Asset Retirement and Environmental Obligations&#8221;
requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is incurred with the associated
ARO capitalized as part of the carrying cost of the asset. The recognition of an ARO requires that management make numerous estimates,
assumptions and judgments regarding such factors as estimated probabilities, timing of settlements, material and service costs, current
technology, laws and regulations, and credit adjusted risk-free rate to be used. We develop estimates for the cost of these activities
based on our evaluation of site-specific facts and circumstances, such as the existence of structures and other improvements that would
need to be dismantled and the length of the post-closure period as determined by the applicable regulatory agency, among other things.
Included in our cost estimates are our interpretation of current regulatory requirements and any proposed regulatory changes. These cost
estimates may change in the future due to various circumstances including, but not limited to, permit modifications, changes in legislation
or regulations, technological changes and results of environmental studies. Our cost estimates are calculated using internal sources
as well as input from third-party experts. This estimate is inflated, using an inflation rate, to the expected time at which the closure
will occur, and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&#8217;s are included within buildings
as part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial
measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions
to either the timing or the amount of the original estimate of undiscounted cash flow. Increases in the ARO liability due to passage
of time impact net income as accretion expense and are included in cost of goods sold in the Consolidated Statements of Operations. Changes
in the estimated future cash flows costs underlying the obligations (resulting from changes or expansion at the facilities) require adjustment
to the ARO liability calculated and are capitalized and charged as depreciation expense, in accordance with our depreciation policy.</span></p>

is determined in accordance with ASC 740, &#8220;Income Taxes.&#8221; As part of the process of preparing our consolidated financial statements,
we are required to estimate our income taxes in each of the jurisdictions in which we operate. We record this amount as a provision or
benefit for taxes<i>.</i> This process involves estimating our actual current tax exposure, including assessing the risks associated with
tax audits, and assessing temporary differences resulting from different treatment of items for tax and accounting purposes. These differences
result in deferred tax assets and liabilities.</p>

a valuation allowance for portions of such assets that we believe will not be realized. In performing this review, we make estimates and
assumptions regarding projected future taxable income, the expected timing of the reversals of existing temporary differences and the
implementation of&#160; tax planning strategies. A change in these assumptions could cause an increase or decrease to the valuation allowance
which could materially impact our results of operations.&#160;</span></p>

Conditions. </i>Our business continues to be heavily dependent on services that we provide to governmental clients, primarily as subcontractors
for others who are prime contractors to government authorities (particularly the DOE and DOD) or directly as the prime contractor. We
believe demand for our services will continue to be subject to fluctuations due to a variety of factors beyond our control, including
without limitation, the economic conditions, the manner in which the government entity will be required to spend funding to remediate
various sites, and potential COVID-19 impact. In addition, our U.S. governmental contracts and subcontracts relating to activities at
governmental sites are generally subject to termination for convenience at any time at the option of the government. Our TOAs with the
Canadian government also provided that the government may terminate a TOA at any time for convenience. Significant reductions in the
level of governmental funding or specifically mandated levels for different programs that are important to our business could have a
material adverse impact on our business, financial position, results of operations and cash flows.</span></p>

been completed. CNL may terminate the TOA at any time for convenience. As of December 31, 2022, PF Canada has approximately $1,853,000
in unpaid receivables due from CNL as a result of work performed under the TOA. Additionally, CNL has approximately $1,060,000 in contractual
holdback under the TOA that is payable to PF Canada. CNL also established a bond securing approximately $1,900,000 (CAD) to cover certain

equipment suppliers for the construction of these equipment. Due to supply chain challenges, we previously experienced a delay in the
delivery of a new waste processing unit to us by our supplier due to shortage of parts required for the construction of the unit, among
other things, This supply chain interruption delayed deployment of our new technology which negatively impacted our revenue for 2021
and the first quarter of 2022 as associated revenue was not able to be generated. Deployment of this unit commenced in mid-May of 2022.

the result of inflationary pressures that could further reduce profitability. We may attempt to increase our sales prices in order to
maintain satisfactory margin; however, competitive pressures in our industry may have the effect of inhibiting our ability to reflect
these increased costs in the prices of our services that we provide to our customers and therefore reduce our profitability.</span></p>

Company&#8217;s 2022 financial results continued to be impacted by COVID-19, among other things. The Company&#8217;s Treatment Segment
began to see steady improvements in waste receipts starting in the second quarter of 2022 from certain customers who had previously delayed
waste shipments due, in part, from the impact of COVID-19. This positive trend was negatively impacted by occurrences of severe weather
conditions which resulted in temporary delays in waste shipments from certain customers and a temporary shortage in skilled production
personnel which peaked through the fourth quarter of 2022 at one of the Company&#8217;s facilities. In early part of 2022, the Company&#8217;s Services Segment continued to experience delays/curtailments in
project work by certain customers since the award of projects to us late in the second quarter of 2021 due to COVID-19 impact and/or
administrative delays. However, starting in the second quarter of 2022, work under these projects had resumed/increased as the pandemic
impacts began to subside and has since reached full operational status.</span></p>

Company&#8217;s cash flow requirements during the twelve months ended December 31, 2022 were primarily financed by its operations, cash
on hand and credit facility availability. The Company&#8217;s cash flow requirements for the next twelve months will consist primarily
of general working capital needs, scheduled principal payments on its debt obligations, remediation projects, and planned capital expenditures.
The Company plans to fund these requirements from its operations, credit facility availability, cash on hand and a refund that it expects
to receive under the Employee Retention Credit program under the CARES Act (see a discussion of this expected refund in &#8220;Note 11
&#8211; The Coronavirus Aid, Relief, and Economic Security Act (&#8220;CARES ACT) &#8211; Employee Retention Credit (&#8220;ERC&#8221;)&#8221;).
The Company continues to explore all sources of increasing its capital and/or liquidity and to improve its revenue and working capital,
including either amending our existing lines of credit, obtaining new term loans or entering into equity transactions. There are no assurances
that we will be successful in increasing our liquidity though these efforts. The Company is continually reviewing operating costs and
reviewing the possibility of further reducing operating costs and non-essential expenditures to bring them in line with revenue levels,
when necessary. At this time, the Company believes that its cash flows from operations, available liquidity from its credit facility,
cash on hand and the expected refund from the ERC program should be sufficient to fund its operations for the next twelve months. The
Company continues to closely monitor any potential impact from the countries&#8217; economic conditions and COVID-19 pandemic on all
aspects of our business.</span></p>

the fourth quarter of 2022, the Company adopted ASU 2016-13, &#8220;Credit Losses (Topic 326) Measurement of Credit Losses on Financial
Instruments.&#8221; This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial
instruments, including accounts receivable. Accounts receivable are customer obligations due under normal trade terms requiring payment
within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The new standard requires
entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivbles
that are current or not yet due, which were not considered under the previous accounting guidance. In accordance with ASU 2016-13, the
Company&#8217;s expected loss allowance methodology for receivables is developed using historical collection experience, current and
future economic and market conditions that may affect customers&#8217; ability to pay, and a review of the current status of customers&#8217;
accounts receivables. The Company does not apply a credit loss allowance to government related receivables due to our past successful
experience in their collectability. The Company&#8217;s monitoring activities include routine follow-up on past due accounts and consideration
of customers&#8217; financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts receivable
balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible
and subsequently written off. The write off process involves approvals from senior management based on required approval thresholds.</span></p>

receivables are generated by differences between invoicing timing and our over time revenue recognition methodology used for revenue
recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes
the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to
the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition
milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons which
include: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for
analytical testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks
relating to these delays can take months to complete but are generally completed within twelve months.</span></p>

Company&#8217;s operating lease right-of-use (&#8220;ROU&#8221;) assets and operating lease liabilities represent primarily leases for
office and warehouse spaces used to conduct our business. These leases have remaining terms of approximately one to seven years which
include additional options to renew. The Company includes renewal options in valuing its ROU assets and liabilities when it determines
that it is reasonably certain to exercise these renewal options. As most of our operating leases do not provide an implicit rate, the
Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental
borrowing rate is determined based on the Company&#8217;s secured borrowing rate, lease terms and current economic environment. Some
of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping
services). The Company has elected the practical expedient to account for lease component and non-lease component as a single component
for all leases under ASU 2016-02. Lease expense for operating leases is recognized on a straight-line basis over the lease term.</span></p>

to lease the property. Accordingly, a reassessment of this lease was performed which resulted in reclassification of this lease to an
operating lease. The Company&#8217;s finance leases have remaining terms of approximately one to three years. See &#8220;Property and

for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the
asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as
estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted
risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur,
and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&#8217;s are included within buildings as
part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement
of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion

a single, comprehensive revenue recognition model for all contracts with customers. Under ASC 606, a five-step process is utilized in
order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration
it expects to receive in exchange for those goods or services. Under ASC 606, a performance obligation is a promise in a contract to
transfer a distinct good or service to the customer and is the unit of account. A contract transaction price is allocated to each distinct
performance obligation and recognized as revenues as the performance obligation is satisfied.</span></p>

stock-based payments to employees and nonemployees, including grant of options, to be recognized in the Statement of Operations based
on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which
requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise price of the
award, the expected term, the expected volatility of our stock over the stock-based award&#8217;s expected term, the risk-free interest
rate over the award&#8217;s expected term, and the expected annual dividend yield. The Company accounts for forfeitures when they occur.</span></p>

financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities
are required to apply the standard&#8217;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the

Accounting Standard (&#8220;IAS&#8221;) 20, Accounting for Government Grants and Disclosure of Government Assistance. In accordance with
IAS 20, management determined it has reasonable assurance for receipt of the ERC and recorded the expected refund as other income (within
&#8220;Other income (expense)&#8221;) on the Company&#8217;s Consolidated Statements of Operations and other receivables (within &#8220;Prepaid
and other assets&#8221;) on the Company&#8217;s Consolidated Balance Sheets. For federal income tax purposes, this item was treated as
a reduction in payroll costs for 2021, the year in which the costs originated. This resulted in a timing difference for the benefit between
financial statement inclusion and tax inclusion between 2021 and 2022. This timing difference does not impact the Company&#8217;s effective
tax rate.</span></p>

Company regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable income. In conducting this
assessment, the Company considers projected future taxable income and ongoing tax planning strategies, then records a valuation allowance
to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized. As of September
30, 2021, the Company determined that it was more likely than not that it would be able to realize a portion of the deferred income tax
assets. As a result, a deferred income tax benefit in the amount of approximately $<span id="xdx_903_eus-gaap--IncomeTaxReconciliationChangeInDeferredTaxAssetsValuationAllowance_c20210701__20210930_zuIGQ4N5vUla" title="Valuation allowance"><ix:nonFraction name="us-gaap:IncomeTaxReconciliationChangeInDeferredTaxAssetsValuationAllowance" contextRef="From2021-07-012021-09-30" format="ixt:numdotdecimal" decimals="0" unitRef="USD">2,351,000</ix:nonFraction></span> attributable to the valuation allowance

subsidiary&#8217;s tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore
has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the years ended December 31, 2022 and
2021. As the Canada and United Kingdom foreign subsidiaries are in loss positions for 2022, no GILTI inclusion is expected for these

maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Securities

of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally
accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent
or detect misstatements or fraudulent acts. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures
may deteriorate. A control system, no matter how well designed, can provide only reasonable assurance with respect to financial statement
preparation and presentation.</p>

control over financial reporting as described below. A material weakness is defined as a deficiency, or a combination of deficiencies,
in internal control over financial reporting, such that there is reasonable possibility that a material misstatement of a Company&#8217;s
annual or interim financial statements will not be prevented or detected on a timely basis.</p>

terms and conditions were not appropriately evaluated in accordance with ASC 606, &#8220;Revenue from Contracts with Customers.&#8221;

complex revenue transactions. The material weakness identified resulted in errors in the Company&#8217;s books and records in fiscal year
2021 which led to audit adjustments. However, the errors arising from the underlying revenue adjustments were not material to the financial
statements reported in any interim or annual period and therefore, did not result in a revision to any previously filed financial statements.</p>

Capital Bank AG, a banking institution regulated by the banking regulations of Austria, has represented to the Company that as of February
1, 2023, it holds of record as a nominee for, and as an agent of, certain accredited investors, 1,897,794 shares of our Common Stock.
Schelhammer Capital Bank AG has also represented to the Company that none of the investors, individually or as a group, as the term &#8220;group&#8221;
is defined under Rule 13d-5(b) of the Exchange Act, beneficially owns more than 4.9% of our Common Stock. Additionally, the investors
for whom Schelhammer Capital Bank AG acts as nominee with respect to such shares maintain full voting and dispositive power over the
Common Stock beneficially owned by such investors, and Schelhammer Capital Bank AG has neither voting nor investment power over such
shares. Accordingly, Schelhammer Capital Bank AG believes that (i) it is not the beneficial owner, as such term is defined in Rule 13d-3
of the Exchange Act, of the shares of Common Stock registered in Schelhammer Capital Bank AG&#8217;s name because (a) Schelhammer Capital
Bank AG holds the Common Stock as a nominee only, (b) Schelhammer Capital Bank AG has neither voting nor investment power over such shares,
and (c) Schelhammer Capital Bank AG has not nominated or sought to nominate, and does not intend to nominate in the future, any person
to serve as a member of our Board; and (ii) it is not required to file reports under Section 16(a) of the Exchange Act or to file either
Schedule 13D or Schedule 13G in connection with the shares of our Common Stock registered in the name of Schelhammer Capital Bank AG.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">If
the representations of, or information provided by Schelhammer Capital Bank AG, are incorrect or Schelhammer Capital Bank AG was historically
acting on behalf of its investors as a group, rather than on behalf of each investor independent of other investors, then Schelhammer
Capital Bank AG and/or the investor group would have become a beneficial owner of more than 10% of our Common Stock on February 9, 1996,
as a result of the acquisition on such date of 1,100 shares of our Preferred Stock that were convertible into a maximum of 256,560 shares
of our Common Stock. If either Schelhammer Capital Bank AG or a group of Schelhammer Capital Bank AG&#8217;s investors became a beneficial
owner of more than 10% of our Common Stock on February 9, 1996, or at any time thereafter, and thereby required to file reports under
Section 16(a) of the Exchange Act, then Schelhammer Capital Bank AG has failed to file a Form 3 or any Forms 4 or 5 since February 9,
1996. (See &#8220;Item 12 - Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters &#8211; Security

Compensation Committee has the latitude to design cash and equity-based incentive compensation programs to promote high performance and
achievement of our corporate objectives by directors and the NEOs, encourage the growth of stockholder value and enable employees to
participate in our long-term growth and profitability. The Compensation Committee may grant stock options and/or performance bonuses.
In granting these awards, the Compensation Committee may establish any conditions or restrictions it deems appropriate. In addition,
the CEO has discretionary authority to grant stock options to certain high-performing executives or officers, subject to the approval
of the Compensation Committee. The exercise price for each stock option granted is at or above the market price of our Common Stock on
the date of grant. Stock options may be awarded to newly hired or promoted executives at the discretion of the Compensation Committee.
Grants of stock options to eligible newly hired executive officers are generally made at the next regularly scheduled Compensation Committee
meeting following the hire date.</span></p>

January 20, 2022, the Compensation Committee and the Board approved individual MIPs for the calendar year 2022 for each of the NEOs.
Each of the MIPs was effective January 1, 2022.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
performance compensation payable under each MIP was based upon meeting certain of the Company&#8217;s separate target objectives during
2022 as described in each of the MIPs below. The Compensation Committee believes performance compensation payable under each of the MIPs
should be based on achievement of at least 75% of EBITDA (earnings before interest, taxes, depreciation and amortization), a non-GAAP
financial measurement, as the Company believes that this target provides a better indicator of operating performance as it excludes certain
non-cash items. EBITDA has certain limitations as it does not reflect all items of income or cash flows that affect the Company&#8217;s
financial performance under GAAP. No performance compensation was earned for each of the target objectives under any of the MIPs for
2022 since a minimum of 75% of the EBITDA target was not achieved.</span></p>

targets set forth in each of the 2022 MIPs took into account the Board-approved budget for 2022 as well as the Compensation Committee&#8217;s
expectation for performance that in its estimation would warrant payment of incentive cash compensation. In formulating certain targets,
the Compensation Committee and the Board considered 2021 results, economic conditions, potential continued impact of COVID-19 and forecasts
for 2022 government spending.</span></p>

account for stock-based compensation in accordance with ASC 718, &#8220;Compensation &#8211; Stock Compensation.&#8221; ASC 718 establishes
accounting standards for entity exchanges of equity instruments for goods or services. It also addresses transactions in which an entity
incurs liabilities in exchange for goods or services that are based on the fair value of the entity&#8217;s equity instruments or that
may be settled by the issuance of those equity instruments. ASC 718 requires all stock-based payments to employees, including grants
of employee stock options, to be recognized in the income statement based on their fair values. The Company uses the Black-Scholes option-pricing
model to determine the fair-value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the fair
value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company&#8217;s
stock over the option&#8217;s expected term, the risk-free interest rate over the option&#8217;s expected term, and the expected annual
dividend yield. We recognize stock-based compensation expense using a straight-line amortization method over the requisite period, which
is the vesting period of the stock option grant. </span></p>

believe that it is important for our directors to have a personal interest in our success and growth and for their interests to be aligned
with those of our stockholders; therefore, under our 2003 Outside Directors Plan, each outside director is granted a 10-year NQSO to
purchase up to 20,000 shares of Common Stock on the date such director is initially elected to the Board, and receives on each re-election
date a NQSO to purchase up to another 10,000 shares of our Common Stock, with the exercise price being the fair market value of the Common
Stock preceding the option grant date. Common Stock shares subject to option granted vest at 25% per year, beginning on the first anniversary
date of the grant and no option shall be exercisable after the expiration of ten years from the date the option is granted. At December
31, 2022, options to purchase 262,400 shares of Common Stock were outstanding under the 2003 Outside Directors Plan, of which 139,900

The number of shares received by each director is calculated based on 75% of the fair market value of the Common Stock determined on
the business day immediately preceding the date that the quarterly fee is due. The balance of each director&#8217;s fee, if any, is payable

Common Stock beneficially owned by such investors, and Schelhammer Capital Bank AG has neither voting nor investment power over such

Common Stock is listed on the Nasdaq Capital Market. Rule 5605 of the Nasdaq Marketplace Rules requires a majority of a listed company&#8217;s
board of directors to be comprised of independent directors. In addition, the Nasdaq Marketplace Rules require that, subject to specified
exceptions, each member of a listed company&#8217;s audit, compensation and nominating and corporate governance committees be independent
under applicable provisions of the Securities Exchange Act of 1934, as amended (the &#8220;Exchange Act&#8221;). Audit committee members
must also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also
satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under Nasdaq Rule 5605(a)(2), a director will only
qualify as an &#8220;independent director&#8221; if, in the opinion of our Board, that person does not have a relationship that would
interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent
for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her
capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any
consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person
of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board must consider,
for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director
has a relationship to such company which is material to that director&#8217;s ability to be independent from management in connection
with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including
any consulting advisory or other compensatory fee paid by such company to the director; and whether the director is affiliated with the
company or any of its subsidiaries or affiliates.</span></p>

Board annually undertakes a review of the composition of our Board of Directors and its committees and the independence of each director.
Based upon information requested from and provided by each director concerning his background, employment and affiliations, including
family relationships, our Board of Directors has determined that Ms. Kerry C. Duggan and each of Messrs. Thomas P. Bostick, Joseph T.
Grumski, Joe R. Reeder, Larry M. Shelton, Zach P. Wamp and Mark A. Zwecker is an &#8220;independent director&#8221; as defined under
the Nasdaq Marketplace Rules. Our Board of Directors has also determined that each member of our Audit Committee, consisting of Mark
A. Zwecker (Chairperson), Joseph T. Grumski, and Larry M. Shelton, and each member of our Compensation Committee, consisting of Joseph
T. Grumski (Chairperson), Zach P. Wamp and Mark A. Zwecker satisfy the independence standards for such committees established by the
Commission and the Nasdaq Marketplace Rules, as applicable. In making such determination, our Board of Directors considered the relationships
that each such non-employee director has with our Company and all other facts and circumstances our Board of Directors deemed relevant
in determining independence, including the beneficial ownership of our capital stock by each non-employee director.</span></p>

Company&#8217;s 2022 financial results continued to be impacted by COVID-19, among other things. The Company&#8217;s Treatment Segment
began to see steady improvements in waste receipts starting in the second quarter of 2022 from certain customers who had previously delayed
waste shipments due, in part, from the impact of COVID-19. This positive trend was negatively impacted by occurrences of severe weather
conditions which resulted in temporary delays in waste shipments from certain customers and a temporary shortage in skilled production
personnel which peaked through the fourth quarter of 2022 at one of the Company&#8217;s facilities. In early part of 2022, the Company&#8217;s Services Segment continued to experience delays/curtailments in
project work by certain customers since the award of projects to us late in the second quarter of 2021 due to COVID-19 impact and/or
administrative delays. However, starting in the second quarter of 2022, work under these projects had resumed/increased as the pandemic
impacts began to subside and has since reached full operational status.</span></p>

2022, the Company continued to realize delays in procurement and planning on behalf of our government clients that saw easing through
the second half of the year. Heading into 2023, the Company expects to see continued improvements in waste receipts and continued increases

impact of COVID-19 and economic impacts.</span></p>

Company&#8217;s cash flow requirements during the twelve months ended December 31, 2022 were primarily financed by its operations, cash
on hand and credit facility availability. The Company&#8217;s cash flow requirements for the next twelve months will consist primarily
of general working capital needs, scheduled principal payments on its debt obligations, remediation projects, and planned capital expenditures.
The Company plans to fund these requirements from its operations, credit facility availability, cash on hand and a refund that it expects
to receive under the Employee Retention Credit program under the CARES Act (see a discussion of this expected refund in &#8220;Note 11
&#8211; The Coronavirus Aid, Relief, and Economic Security Act (&#8220;CARES ACT) &#8211; Employee Retention Credit (&#8220;ERC&#8221;)&#8221;).
The Company continues to explore all sources of increasing its capital and/or liquidity and to improve its revenue and working capital,
including either amending our existing lines of credit, obtaining new term loans or entering into equity transactions. There are no assurances
that we will be successful in increasing our liquidity though these efforts. The Company is continually reviewing operating costs and
reviewing the possibility of further reducing operating costs and non-essential expenditures to bring them in line with revenue levels,
when necessary. At this time, the Company believes that its cash flows from operations, available liquidity from its credit facility,
cash on hand and the expected refund from the ERC program should be sufficient to fund its operations for the next twelve months. The
Company continues to closely monitor any potential impact from the countries&#8217; economic conditions and COVID-19 pandemic on all
aspects of our business.</span></p>

the fourth quarter of 2022, the Company adopted ASU 2016-13, &#8220;Credit Losses (Topic 326) Measurement of Credit Losses on Financial
Instruments.&#8221; This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial
instruments, including accounts receivable. Accounts receivable are customer obligations due under normal trade terms requiring payment
within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The new standard requires
entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivbles
that are current or not yet due, which were not considered under the previous accounting guidance. In accordance with ASU 2016-13, the
Company&#8217;s expected loss allowance methodology for receivables is developed using historical collection experience, current and
future economic and market conditions that may affect customers&#8217; ability to pay, and a review of the current status of customers&#8217;
accounts receivables. The Company does not apply a credit loss allowance to government related receivables due to our past successful
experience in their collectability. The Company&#8217;s monitoring activities include routine follow-up on past due accounts and consideration
of customers&#8217; financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts receivable
balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible
and subsequently written off. The write off process involves approvals from senior management based on required approval thresholds.</span></p>

receivables are generated by differences between invoicing timing and our over time revenue recognition methodology used for revenue
recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes
the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to
the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition
milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons which
include: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for
analytical testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks
relating to these delays can take months to complete but are generally completed within twelve months.</span></p>

Company&#8217;s operating lease right-of-use (&#8220;ROU&#8221;) assets and operating lease liabilities represent primarily leases for
office and warehouse spaces used to conduct our business. These leases have remaining terms of approximately one to seven years which
include additional options to renew. The Company includes renewal options in valuing its ROU assets and liabilities when it determines
that it is reasonably certain to exercise these renewal options. As most of our operating leases do not provide an implicit rate, the
Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental
borrowing rate is determined based on the Company&#8217;s secured borrowing rate, lease terms and current economic environment. Some
of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping

leases primarily consist of processing and transport equipment used by our facilities&#8217; operations. The Company&#8217;s finance
leases also included a building with land utilized for our waste treatment operations which included a purchase option. During the third
quarter of 2021, the Company concluded that it was more likely than not that it would not exercise this purchase option but will continue
to lease the property. Accordingly, a reassessment of this lease was performed which resulted in reclassification of this lease to an
operating lease. The Company&#8217;s finance leases have remaining terms of approximately one to three years. See &#8220;Property and
Equipment&#8221; above for assets recorded under financed leases. Borrowing rates for our finance leases are either explicitly stated
in the lease agreements or implicitly determined from available terms in the lease agreements.</span></p>

closure costs represent our estimated environmental liability to clean up our facilities, as required by our permits, in the event of

for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the
asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as
estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted
risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur,
and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&#8217;s are included within buildings as
part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement
of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion
at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation expense, in accordance with
the Company&#8217;s depreciation policy.</span></p>

CARES Act, which was enacted on March 27, 2020, provides an Employee Retention Credit (&#8220;ERC&#8221;) for qualifying businesses keeping
employees on their payroll during the COVID-19 pandemic. The ERC was subsequently amended by the Taxpayer Certainty and Disaster Tax
Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended
the ERC availability and guidelines under the CARES Act. Following these amendments, the Company determined that it was eligible for
the ERC, and as a result of the foregoing legislations, is eligible to claim a refundable tax credit against the <span id="xdx_906_ecustom--EmployeeRetentionCreditsDescription_c20210701__20210930_zpMLEQp7ShEl" title="Employee retention credits, description">Company&#8217;s share

quarter in 2021. For purposes of the amended ERC, an eligible employer is defined as having experienced a significant (20% or more) decline
in gross receipts during one or more of the first three 2021 calendar quarters when compared to 2019.</span></span></p>

the third quarter of 2022, the Company determined it was eligible for the ERC and amended its third quarter 2021 employer payroll tax
filings claiming a refund from the U.S. Treasury in the amount of approximately $<span id="xdx_902_eus-gaap--OtherNonoperatingIncome_pp0p0_c20210701__20210930__us-gaap--IncomeStatementLocationAxis__us-gaap--OtherNonoperatingIncomeExpenseMember_zPDqsI8PXdMj" title="Non-operating income">1,975,000</span>. As there is no authoritative guidance under
U.S. GAAP on accounting for government assistance to for-profit business entities, we account for the ERC by analogy to International
Accounting Standard (&#8220;IAS&#8221;) 20, Accounting for Government Grants and Disclosure of Government Assistance. In accordance with
IAS 20, management determined it has reasonable assurance for receipt of the ERC and recorded the expected refund as other income (within
&#8220;Other income (expense)&#8221;) on the Company&#8217;s Consolidated Statements of Operations and other receivables (within &#8220;Prepaid
and other assets&#8221;) on the Company&#8217;s Consolidated Balance Sheets. For federal income tax purposes, this item was treated as
a reduction in payroll costs for 2021, the year in which the costs originated. This resulted in a timing difference for the benefit between
financial statement inclusion and tax inclusion between 2021 and 2022. This timing difference does not impact the Company&#8217;s effective
tax rate.</span></p>

Company regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable income. In conducting this
assessment, the Company considers projected future taxable income and ongoing tax planning strategies, then records a valuation allowance
to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized. As of September
30, 2021, the Company determined that it was more likely than not that it would be able to realize a portion of the deferred income tax
assets. As a result, a deferred income tax benefit in the amount of approximately $<span id="xdx_903_eus-gaap--IncomeTaxReconciliationChangeInDeferredTaxAssetsValuationAllowance_c20210701__20210930_zuIGQ4N5vUla" title="Valuation allowance">2,351,000</span> attributable to the valuation allowance
release on beginning of year deferred tax assets primarily related to U.S. Federal income taxes was realized in the three months ended
September 30, 2021. The Company had previously maintained a full valuation allowance against its net deferred income tax assets. The
Company continues to maintain a valuation allowance against certain state and foreign tax attributes that may not be realizable along
with the capital loss carryover generated during 2021 that it does not expect to realize.</span></p>

subsidiary&#8217;s tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore
has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the years ended December 31, 2022 and
2021. As the Canada and United Kingdom foreign subsidiaries are in loss positions for 2022, no GILTI inclusion is expected for these
entities for the current year. In addition, the aforementioned sale of PFM Poland in 2021 did not result in any GILTI inclusion.</span></p>

the fourth quarter of 2022, the Company adopted ASU 2016-13, &#8220;Credit Losses (Topic 326) Measurement of Credit Losses on Financial
Instruments.&#8221; This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial
instruments, including accounts receivable. Accounts receivable are customer obligations due under normal trade terms requiring payment
within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The new standard requires
entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivbles
that are current or not yet due, which were not considered under the previous accounting guidance. In accordance with ASU 2016-13, the
Company&#8217;s expected loss allowance methodology for receivables is developed using historical collection experience, current and
future economic and market conditions that may affect customers&#8217; ability to pay, and a review of the current status of customers&#8217;
accounts receivables. The Company does not apply a credit loss allowance to government related receivables due to our past successful
experience in their collectability. The Company&#8217;s monitoring activities include routine follow-up on past due accounts and consideration
of customers&#8217; financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts receivable
balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible
and subsequently written off. The write off process involves approvals from senior management based on required approval thresholds.</span></p>

receivables are generated by differences between invoicing timing and our over time revenue recognition methodology used for revenue
recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes
the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to
the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition
milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons which
include: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for
analytical testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks
relating to these delays can take months to complete but are generally completed within twelve months.</span></p>

Company&#8217;s operating lease right-of-use (&#8220;ROU&#8221;) assets and operating lease liabilities represent primarily leases for
office and warehouse spaces used to conduct our business. These leases have remaining terms of approximately one to seven years which
include additional options to renew. The Company includes renewal options in valuing its ROU assets and liabilities when it determines
that it is reasonably certain to exercise these renewal options. As most of our operating leases do not provide an implicit rate, the
Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental
borrowing rate is determined based on the Company&#8217;s secured borrowing rate, lease terms and current economic environment. Some
of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping
services). The Company has elected the practical expedient to account for lease component and non-lease component as a single component
for all leases under ASU 2016-02. Lease expense for operating leases is recognized on a straight-line basis over the lease term.</span></p>

of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion
at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation expense, in accordance with
the Company&#8217;s depreciation policy.</span></p>

of taxes that are currently payable and deferred taxes that relate to the temporary differences between financial reporting carrying
values and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected
to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred

740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all

records a valuation allowance to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not
to be realized.</span></p>

of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out
disclosure requirements to enhance transparency of an entity&#8217;s tax reserves. The Company recognizes accrued interest and income

requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise price of the
award, the expected term, the expected volatility of our stock over the stock-based award&#8217;s expected term, the risk-free interest

rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied

its credit facility were impacted by these ASUs. During the third quarter of 2022, the Company entered into an amendment dated August
29, 2022 to its loan agreement which replaced the LIBOR option with the Secured Overnight Finance Rate (&#8220;SOFR&#8221;) option under

based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale
debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most
financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities
are required to apply the standard&#8217;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the
first reporting period in which the guidance is adopted. In November 2019, FASB issued ASU 2019-10, &#8220;Financial Instruments &#8211;

began to see steady improvements in waste receipts starting in the second quarter of 2022 from certain customers who had previously delayed
waste shipments due, in part, from the impact of COVID-19. This positive trend was negatively impacted by occurrences of severe weather
conditions which resulted in temporary delays in waste shipments from certain customers and a temporary shortage in skilled production
personnel which peaked through the fourth quarter of 2022 at one of the Company&#x2019;s facilities. In early part of 2022, the Company&#x2019;s Services Segment continued to experience delays/curtailments in
project work by certain customers since the award of projects to us late in the second quarter of 2021 due to COVID-19 impact and/or
administrative delays. However, starting in the second quarter of 2022, work under these projects had resumed/increased as the pandemic
impacts began to subside and has since reached full operational status.&lt;/span&gt;&lt;/p&gt;

2022, the Company continued to realize delays in procurement and planning on behalf of our government clients that saw easing through
the second half of the year. Heading into 2023, the Company expects to see continued improvements in waste receipts and continued increases
in project work from contracts recently won and bids submitted in both segments that are awaiting awards, subject to potential
impact of COVID-19 and economic impacts.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s cash flow requirements during the twelve months ended December 31, 2022 were primarily financed by its operations, cash
on hand and credit facility availability. The Company&#x2019;s cash flow requirements for the next twelve months will consist primarily
of general working capital needs, scheduled principal payments on its debt obligations, remediation projects, and planned capital expenditures.
The Company plans to fund these requirements from its operations, credit facility availability, cash on hand and a refund that it expects
to receive under the Employee Retention Credit program under the CARES Act (see a discussion of this expected refund in &#x201c;Note 11
&#x2013; The Coronavirus Aid, Relief, and Economic Security Act (&#x201c;CARES ACT) &#x2013; Employee Retention Credit (&#x201c;ERC&#x201d;)&#x201d;).
The Company continues to explore all sources of increasing its capital and/or liquidity and to improve its revenue and working capital,
including either amending our existing lines of credit, obtaining new term loans or entering into equity transactions. There are no assurances
that we will be successful in increasing our liquidity though these efforts. The Company is continually reviewing operating costs and
reviewing the possibility of further reducing operating costs and non-essential expenditures to bring them in line with revenue levels,
when necessary. At this time, the Company believes that its cash flows from operations, available liquidity from its credit facility,
cash on hand and the expected refund from the ERC program should be sufficient to fund its operations for the next twelve months. The
Company continues to closely monitor any potential impact from the countries&#x2019; economic conditions and COVID-19 pandemic on all
aspects of our business.&lt;/span&gt;&lt;/p&gt;

the fourth quarter of 2022, the Company adopted ASU 2016-13, &#x201c;Credit Losses (Topic 326) Measurement of Credit Losses on Financial
Instruments.&#x201d; This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial
instruments, including accounts receivable. Accounts receivable are customer obligations due under normal trade terms requiring payment
within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The new standard requires
entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivbles
that are current or not yet due, which were not considered under the previous accounting guidance. In accordance with ASU 2016-13, the
Company&#x2019;s expected loss allowance methodology for receivables is developed using historical collection experience, current and
future economic and market conditions that may affect customers&#x2019; ability to pay, and a review of the current status of customers&#x2019;
accounts receivables. The Company does not apply a credit loss allowance to government related receivables due to our past successful
experience in their collectability. The Company&#x2019;s monitoring activities include routine follow-up on past due accounts and consideration
of customers&#x2019; financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts receivable
balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible
and subsequently written off. The write off process involves approvals from senior management based on required approval thresholds.&lt;/span&gt;&lt;/p&gt;

receivables are generated by differences between invoicing timing and our over time revenue recognition methodology used for revenue
recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes
the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to
the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition
milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons which
include: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for
analytical testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks
relating to these delays can take months to complete but are generally completed within twelve months.&lt;/span&gt;&lt;/p&gt;

assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that
the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the
carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount
of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of
the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at
the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.&lt;/span&gt;&lt;/p&gt;

Company accounts for leases in accordance with FASB&#x2019;s ASU 2016-02, &#x201c;Leases (Topic 842).&#x201d; At the inception of an arrangement,
the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease
classifications, recognition, and measurement are then determined at the lease commencement date.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s operating lease right-of-use (&#x201c;ROU&#x201d;) assets and operating lease liabilities represent primarily leases for
office and warehouse spaces used to conduct our business. These leases have remaining terms of approximately one to seven years which
include additional options to renew. The Company includes renewal options in valuing its ROU assets and liabilities when it determines
that it is reasonably certain to exercise these renewal options. As most of our operating leases do not provide an implicit rate, the
Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental
borrowing rate is determined based on the Company&#x2019;s secured borrowing rate, lease terms and current economic environment. Some
of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping
services). The Company has elected the practical expedient to account for lease component and non-lease component as a single component
for all leases under ASU 2016-02. Lease expense for operating leases is recognized on a straight-line basis over the lease term.&lt;/span&gt;&lt;/p&gt;

leases primarily consist of processing and transport equipment used by our facilities&#x2019; operations. The Company&#x2019;s finance
leases also included a building with land utilized for our waste treatment operations which included a purchase option. During the third
quarter of 2021, the Company concluded that it was more likely than not that it would not exercise this purchase option but will continue
to lease the property. Accordingly, a reassessment of this lease was performed which resulted in reclassification of this lease to an
operating lease. The Company&#x2019;s finance leases have remaining terms of approximately one to three years. See &#x201c;Property and
Equipment&#x201d; above for assets recorded under financed leases. Borrowing rates for our finance leases are either explicitly stated
in the lease agreements or implicitly determined from available terms in the lease agreements.&lt;/span&gt;&lt;/p&gt;

assets consist primarily of the recognized value of the permits required to operate our business. Indefinite-lived intangible assets
are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate
that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, a quantitative test is performed
to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over its fair
value. Judgments and estimates are inherent in these analyses and include assumptions for, among other factors, forecasted revenue, gross
margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long-term discount
rates. Impairment testing of our indefinite-lived permits related to our Treatment reporting unit as of October 1, 2022 and 2021 resulted
in no impairment charges.&lt;/span&gt;&lt;/p&gt;

assets that have definite useful lives are amortized using the straight-line method over the estimated useful lives (with the exception

innovation and technical know-how are very important to the success of our business. Our goal is to discover, develop, and bring to market
innovative ways to process waste that address unmet environmental needs and to develop new company service offerings. The Company conducts
research internally and also through collaborations with other third parties. R&amp;amp;D costs consist primarily of employee salaries and
benefits, laboratory costs, third party fees, and other related costs associated with the development and enhancement of new potential

closure costs represent our estimated environmental liability to clean up our facilities, as required by our permits, in the event of
closure. ASC 410, &#x201c;Asset Retirement and Environmental Obligations&#x201d; requires that the discounted fair value of a liability
for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the
asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as
estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted
risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur,
and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&#x2019;s are included within buildings as
part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement
of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion
at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation expense, in accordance with
the Company&#x2019;s depreciation policy.&lt;/span&gt;&lt;/p&gt;

taxes are accounted for in accordance with ASC 740, &#x201c;Income Taxes.&#x201d; Under ASC 740, the provision for income taxes is comprised
of taxes that are currently payable and deferred taxes that relate to the temporary differences between financial reporting carrying
values and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected
to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred
tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.&lt;/span&gt;&lt;/p&gt;

740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all
of the deferred income tax assets will not be realized. The Company regularly assesses the likelihood that the deferred tax asset will
be recovered from future taxable income. The Company considers projected future taxable income and ongoing tax planning strategies, then
records a valuation allowance to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not
to be realized.&lt;/span&gt;&lt;/p&gt;

740 sets out a consistent framework for preparers to use to determine the appropriate recognition and measurement of uncertain tax positions.
ASC 740 uses a two-step approach wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount
of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out
disclosure requirements to enhance transparency of an entity&#x2019;s tax reserves. The Company recognizes accrued interest and income
tax penalties related to unrecognized tax benefits as a component of income tax expense.&lt;/span&gt;&lt;/p&gt;

Company recognizes revenue in accordance with FASB&#x2019;s ASC 606, &#x201c;Revenue from Contracts with Customers.&#x201d; ASC 606 provides
a single, comprehensive revenue recognition model for all contracts with customers. Under ASC 606, a five-step process is utilized in
order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration
it expects to receive in exchange for those goods or services. Under ASC 606, a performance obligation is a promise in a contract to
transfer a distinct good or service to the customer and is the unit of account. A contract transaction price is allocated to each distinct
performance obligation and recognized as revenues as the performance obligation is satisfied.&lt;/span&gt;&lt;/p&gt;

fixed price contracts, the objective of the project is not attained unless all scope items within the contract are completed and all
of the services promised within fixed fee contracts constitute a single performance obligation. Transaction price is estimated based

input method. For the input method, revenue is recognized based on costs incurred on the project relative to the total estimated costs
of the project.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s contracts generally do not give rise to variable consideration. However, from time to time, the Company may submit requests
for equitable adjustments under certain of its government contracts for price or other modifications that are determined to be variable
consideration. The Company estimates the amount of variable consideration to include in the estimated transaction price based on historical
experience with government contracts, anticipated performance and management&#x2019;s best judgment at the time and to the extent it is
probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is resolved. These estimates are re-assessed each reporting period as required.&lt;/span&gt;&lt;/p&gt;

Stock-based payment transactions for acquiring goods and services from nonemployees are also accounted for under ASC 718. ASC 718 requires
stock-based payments to employees and nonemployees, including grant of options, to be recognized in the Statement of Operations based
on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which
requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise price of the
award, the expected term, the expected volatility of our stock over the stock-based award&#x2019;s expected term, the risk-free interest
rate over the award&#x2019;s expected term, and the expected annual dividend yield. The Company accounts for forfeitures when they occur.&lt;/span&gt;&lt;/p&gt;

May 2021, the FASB issued Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2021-04, &#x201c;Earnings Per Share (Topic 206), Debt-Modifications
and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity&#x2019;s
Own Equity (Subtopic 815-40): Issuer&#x2019;s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written
Call Options (a consensus of the FASB Emerging Issues Task Force).&#x201d; ASU 2021-04 addresses issuer&#x2019;s accounting for certain
modifications or exchanges of freestanding equity-classified written call options. This ASU is effective for all entities, for fiscal
years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. The adoption
of this ASU by the Company effective January 1, 2022 did not have a material impact on its financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
March 2020, the FASB issued ASU 2020-04, &#x201c;Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform
on Financial Reporting,&#x201d; which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships
and other transactions affected by the discontinuation of the London Interbank Offered Rate (&#x201c;LIBOR&#x201d;) or by another reference
rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied
prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, &#x201c;Reference Rate Reform (Topic 848):
Scope,&#x201d; which clarified the scope and application of the original guidance. The Company determined that only its obligations under
its credit facility were impacted by these ASUs. During the third quarter of 2022, the Company entered into an amendment dated August
29, 2022 to its loan agreement which replaced the LIBOR option with the Secured Overnight Finance Rate (&#x201c;SOFR&#x201d;) option under
its credit facility. The adoption of these aforementioned ASUs by the Company during the third quarter of 2022 did not have a material
impact to its financial statements (see &#x201c;Note 10 &#x2013; Long Term Debt&#x201d; for a discuss of the Company&#x2019;s credit facility
and the amendment dated August 29, 2022). On December 21, 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral
of the Sunset Date of Topic 848,&#x201d; which extends the period of time entities can utilize the reference rate reform relief guidance
under ASU 2020-04 from December 31, 2022 to December 31, 2024.&lt;/span&gt;&lt;/p&gt;

and various subsequent amendments to the initial guidance (collectively, &#x201c;Topic 326&#x201d;). Topic 326 introduces an approach,
based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale
debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most
financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities
are required to apply the standard&#x2019;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the
first reporting period in which the guidance is adopted. In November 2019, FASB issued ASU 2019-10, &#x201c;Financial Instruments &#x2013;
Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842),&#x201d; which defers the effective date of ASU
2016-13 for public companies that are considered smaller reporting companies (&#x201c;SRC&#x201d;) as defined by the Commission to fiscal
years beginning after December 15, 2022, including interim periods within those fiscal years. The adoption of these ASUs by the Company
during the fourth quarter of 2022 did not have a material impact to its financial statements. &lt;/span&gt;&lt;/p&gt;

and Hedging &#x2013; Contracts in Entity&#x2019;s Own Equity.&#x201d; ASU 2020-06 simplifies the accounting for convertible instruments
by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts
in an entity&#x2019;s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06
is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as an
SRC. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within
those fiscal years. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and disclosures.&lt;/span&gt;&lt;/p&gt;

the fourth quarter of 2022, the Company adopted ASU 2016-13, &#x201c;Credit Losses (Topic 326) Measurement of Credit Losses on Financial
Instruments.&#x201d; This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial
instruments, including accounts receivable. Accounts receivable are customer obligations due under normal trade terms requiring payment
within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The new standard requires
entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivbles
that are current or not yet due, which were not considered under the previous accounting guidance. In accordance with ASU 2016-13, the
Company&#x2019;s expected loss allowance methodology for receivables is developed using historical collection experience, current and
future economic and market conditions that may affect customers&#x2019; ability to pay, and a review of the current status of customers&#x2019;
accounts receivables. The Company does not apply a credit loss allowance to government related receivables due to our past successful
experience in their collectability. The Company&#x2019;s monitoring activities include routine follow-up on past due accounts and consideration
of customers&#x2019; financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts receivable
balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible
and subsequently written off. The write off process involves approvals from senior management based on required approval thresholds.&lt;/span&gt;&lt;/p&gt;

receivables are generated by differences between invoicing timing and our over time revenue recognition methodology used for revenue
recognition purposes. As major processing and contract completion phases are completed and the costs are incurred, the Company recognizes
the corresponding percentage of revenue. Within our Treatment Segment, the facilities experience delays in processing invoices due to
the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition
milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons which
include: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for
analytical testing that is required after the facilities have processed waste but prior to our release of waste for disposal. The tasks
relating to these delays can take months to complete but are generally completed within twelve months.&lt;/span&gt;&lt;/p&gt;

assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that
the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the
carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount
of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of
the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at
the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.&lt;/span&gt;&lt;/p&gt;

Company accounts for leases in accordance with FASB&#x2019;s ASU 2016-02, &#x201c;Leases (Topic 842).&#x201d; At the inception of an arrangement,
the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease
classifications, recognition, and measurement are then determined at the lease commencement date.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s operating lease right-of-use (&#x201c;ROU&#x201d;) assets and operating lease liabilities represent primarily leases for
office and warehouse spaces used to conduct our business. These leases have remaining terms of approximately one to seven years which
include additional options to renew. The Company includes renewal options in valuing its ROU assets and liabilities when it determines
that it is reasonably certain to exercise these renewal options. As most of our operating leases do not provide an implicit rate, the
Company uses its incremental borrowing rate as the discount rate when determining the present value of the lease payments. The incremental
borrowing rate is determined based on the Company&#x2019;s secured borrowing rate, lease terms and current economic environment. Some
of our operating leases include both lease (rent payments) and non-lease components (maintenance costs such as cleaning and landscaping
services). The Company has elected the practical expedient to account for lease component and non-lease component as a single component
for all leases under ASU 2016-02. Lease expense for operating leases is recognized on a straight-line basis over the lease term.&lt;/span&gt;&lt;/p&gt;

leases primarily consist of processing and transport equipment used by our facilities&#x2019; operations. The Company&#x2019;s finance
leases also included a building with land utilized for our waste treatment operations which included a purchase option. During the third
quarter of 2021, the Company concluded that it was more likely than not that it would not exercise this purchase option but will continue
to lease the property. Accordingly, a reassessment of this lease was performed which resulted in reclassification of this lease to an
operating lease. The Company&#x2019;s finance leases have remaining terms of approximately one to three years. See &#x201c;Property and
Equipment&#x201d; above for assets recorded under financed leases. Borrowing rates for our finance leases are either explicitly stated
in the lease agreements or implicitly determined from available terms in the lease agreements.&lt;/span&gt;&lt;/p&gt;

assets consist primarily of the recognized value of the permits required to operate our business. Indefinite-lived intangible assets
are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate
that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, a quantitative test is performed
to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over its fair
value. Judgments and estimates are inherent in these analyses and include assumptions for, among other factors, forecasted revenue, gross
margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long-term discount
rates. Impairment testing of our indefinite-lived permits related to our Treatment reporting unit as of October 1, 2022 and 2021 resulted
in no impairment charges.&lt;/span&gt;&lt;/p&gt;

assets that have definite useful lives are amortized using the straight-line method over the estimated useful lives (with the exception
of customer relationships which are amortized using an accelerated method) and are excluded from our annual intangible asset valuation
review as of October 1. Definite-lived intangible assets are also tested for impairment whenever events or changes in circumstances suggest
impairment might exist.&lt;/span&gt;&lt;/p&gt;

innovation and technical know-how are very important to the success of our business. Our goal is to discover, develop, and bring to market
innovative ways to process waste that address unmet environmental needs and to develop new company service offerings. The Company conducts
research internally and also through collaborations with other third parties. R&amp;amp;D costs consist primarily of employee salaries and
benefits, laboratory costs, third party fees, and other related costs associated with the development and enhancement of new potential
waste treatment processes and new technology and are charged to expense when incurred in accordance with ASC Topic 730, &#x201c;Research

closure costs represent our estimated environmental liability to clean up our facilities, as required by our permits, in the event of
closure. ASC 410, &#x201c;Asset Retirement and Environmental Obligations&#x201d; requires that the discounted fair value of a liability
for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the
asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as
estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted
risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur,
and then discounted back, using a credit adjusted risk free rate, to the present value. ARO&#x2019;s are included within buildings as
part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement
of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion
at the facilities require adjustment to the ARO liability and are capitalized and charged as depreciation expense, in accordance with
the Company&#x2019;s depreciation policy.&lt;/span&gt;&lt;/p&gt;

taxes are accounted for in accordance with ASC 740, &#x201c;Income Taxes.&#x201d; Under ASC 740, the provision for income taxes is comprised
of taxes that are currently payable and deferred taxes that relate to the temporary differences between financial reporting carrying
values and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected
to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred
tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.&lt;/span&gt;&lt;/p&gt;

740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all
of the deferred income tax assets will not be realized. The Company regularly assesses the likelihood that the deferred tax asset will
be recovered from future taxable income. The Company considers projected future taxable income and ongoing tax planning strategies, then
records a valuation allowance to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not
to be realized.&lt;/span&gt;&lt;/p&gt;

740 sets out a consistent framework for preparers to use to determine the appropriate recognition and measurement of uncertain tax positions.
ASC 740 uses a two-step approach wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount
of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out
disclosure requirements to enhance transparency of an entity&#x2019;s tax reserves. The Company recognizes accrued interest and income
tax penalties related to unrecognized tax benefits as a component of income tax expense.&lt;/span&gt;&lt;/p&gt;

Company recognizes revenue in accordance with FASB&#x2019;s ASC 606, &#x201c;Revenue from Contracts with Customers.&#x201d; ASC 606 provides
a single, comprehensive revenue recognition model for all contracts with customers. Under ASC 606, a five-step process is utilized in
order to determine revenue recognition, depicting the transfer of goods or services to a customer at an amount that reflects the consideration
it expects to receive in exchange for those goods or services. Under ASC 606, a performance obligation is a promise in a contract to
transfer a distinct good or service to the customer and is the unit of account. A contract transaction price is allocated to each distinct
performance obligation and recognized as revenues as the performance obligation is satisfied.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Contracts
in our Treatment Segment primarily have a single performance obligation as the promise to receive, treat and dispose of waste is not
separately identifiable in the contract and, therefore, not distinct. Performance obligations are generally satisfied over time using
the input method. Under the input method, the Company uses a measure of progress divided into major phases which include receipt (ranging
from &lt;span id="xdx_900_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--ReceiptMember__srt--RangeAxis__srt--MinimumMember_zgk4Zy1rxXXb" title="Percentage of revenue recognized"&gt;9.0%&lt;/span&gt; to &lt;span id="xdx_900_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--ReceiptMember__srt--RangeAxis__srt--MaximumMember_zoFLidxi9bEd" title="Percentage of revenue recognized"&gt;33%&lt;/span&gt;), treatment/processing (ranging from &lt;span id="xdx_908_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--TreatmentOrProcessingMember__srt--RangeAxis__srt--MinimumMember_zttokJLqzUad" title="Percentage of revenue recognized"&gt;40%&lt;/span&gt; to &lt;span id="xdx_902_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--TreatmentOrProcessingMember__srt--RangeAxis__srt--MaximumMember_zMRkV5AXtEZ" title="Percentage of revenue recognized"&gt;79%&lt;/span&gt;) and shipment/final disposal (ranging from &lt;span id="xdx_906_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--ShipmentOrFinalDisposalMember__srt--RangeAxis__srt--MinimumMember_zWRkYqYHuAYe" title="Percentage of revenue recognized"&gt;9.0%&lt;/span&gt; to &lt;span id="xdx_90E_ecustom--PercentageOfRevenueRecognized_iI_pid_uPure_c20221231__srt--ProductOrServiceAxis__custom--ShipmentOrFinalDisposalMember__srt--RangeAxis__srt--MaximumMember_zTuxo4yTr0W1" title="Percentage of revenue recognized"&gt;27%&lt;/span&gt;). As major processing
phases are completed and the costs are incurred, the proportional percentage of revenue is recognized. Transaction price for Treatment
Segment contracts are determined by the stated fixed rate per unit price as stipulated in the contract.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s primary obligation to customers in time and materials contracts relate to the provision of services to the customer at
the direction of the customer. This provision of services at the request of the customer is the performance obligation, which is satisfied
over time. Revenue earned from time and materials contracts is determined using the input method and is based on contractually defined
billing rates applied to services performed and materials delivered.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

fixed price contracts, the objective of the project is not attained unless all scope items within the contract are completed and all
of the services promised within fixed fee contracts constitute a single performance obligation. Transaction price is estimated based
upon the estimated cost to complete the overall project. Revenue from fixed price contracts is recognized over time primarily using the
input method. For the input method, revenue is recognized based on costs incurred on the project relative to the total estimated costs
of the project.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

discussed above for the Treatment and Services Segments, the Company&#x2019; revenue is generally recognized using the input method. This
method of measuring progress provides a faithful depiction of the transfer to goods and services because the costs incurred are expected
to be substantially proportionate to the Company&#x2019;s satisfaction of the performance obligation.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"/&gt;&#160;&lt;/p&gt;

with our customers within our Treatment Segment are generally short term with an original expected length of one year or less. For the
Services Segment, contracts with our customers generally have original terms ranging from one year or less to approximately twenty-four
months. The Company&#x2019;s contracts and subcontracts relating to activities at governmental sites generally allow for termination for
convenience at any time at the government&#x2019;s option without payment of a substantial penalty. &lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s contracts generally do not give rise to variable consideration. However, from time to time, the Company may submit requests
for equitable adjustments under certain of its government contracts for price or other modifications that are determined to be variable
consideration. The Company estimates the amount of variable consideration to include in the estimated transaction price based on historical
experience with government contracts, anticipated performance and management&#x2019;s best judgment at the time and to the extent it is
probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is resolved. These estimates are re-assessed each reporting period as required.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

our Services Segment, there are service contracts which provide that the Company has a right to consideration from a customer in an amount
that corresponds directly with the value to the customer of our performance completed to date. For those contracts, the Company has utilized
the practical expedient in ASC 606-10-55-18, which allows the Company to recognize revenue in the amount for which we have the right
to invoice; accordingly, the Company does not disclose the value of remaining performance obligations for those contracts.&lt;/span&gt;&lt;/p&gt;

Stock-based payment transactions for acquiring goods and services from nonemployees are also accounted for under ASC 718. ASC 718 requires
stock-based payments to employees and nonemployees, including grant of options, to be recognized in the Statement of Operations based
on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which
requires subjective assumptions. Assumptions used to estimate the fair value of stock-based awards include the exercise price of the
award, the expected term, the expected volatility of our stock over the stock-based award&#x2019;s expected term, the risk-free interest
rate over the award&#x2019;s expected term, and the expected annual dividend yield. The Company accounts for forfeitures when they occur.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Certain
assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded
at fair value on a nonrecurring basis. Fair value is determined based on the exchange price that would be received for an asset or paid
to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction
between market participants. The three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:&lt;/span&gt;&lt;/p&gt;

assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active,
or other inputs that are observable or can be corroborated by observable market data.&lt;/span&gt;&lt;/p&gt;

available assumptions made by other market participants.&lt;/span&gt;&lt;/p&gt;

instruments include cash (Level 1), accounts receivable, accounts payable, and debt obligations (Level 3). Credit is extended to customers
based on an evaluation of a customer&#x2019;s financial condition and, generally, collateral is not required. At December 31, 2022 and
December 31, 2021, the fair value of the Company&#x2019;s financial instruments approximated their carrying values. The fair value of
the Company&#x2019;s revolving credit and term loan approximate its carrying value due to the variable interest rate.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
May 2021, the FASB issued Accounting Standards Update (&#x201c;ASU&#x201d;) No. 2021-04, &#x201c;Earnings Per Share (Topic 206), Debt-Modifications
and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity&#x2019;s
Own Equity (Subtopic 815-40): Issuer&#x2019;s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written
Call Options (a consensus of the FASB Emerging Issues Task Force).&#x201d; ASU 2021-04 addresses issuer&#x2019;s accounting for certain
modifications or exchanges of freestanding equity-classified written call options. This ASU is effective for all entities, for fiscal
years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. The adoption
of this ASU by the Company effective January 1, 2022 did not have a material impact on its financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
March 2020, the FASB issued ASU 2020-04, &#x201c;Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform
on Financial Reporting,&#x201d; which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships
and other transactions affected by the discontinuation of the London Interbank Offered Rate (&#x201c;LIBOR&#x201d;) or by another reference
rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied
prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, &#x201c;Reference Rate Reform (Topic 848):
Scope,&#x201d; which clarified the scope and application of the original guidance. The Company determined that only its obligations under
its credit facility were impacted by these ASUs. During the third quarter of 2022, the Company entered into an amendment dated August
29, 2022 to its loan agreement which replaced the LIBOR option with the Secured Overnight Finance Rate (&#x201c;SOFR&#x201d;) option under
its credit facility. The adoption of these aforementioned ASUs by the Company during the third quarter of 2022 did not have a material
impact to its financial statements (see &#x201c;Note 10 &#x2013; Long Term Debt&#x201d; for a discuss of the Company&#x2019;s credit facility
and the amendment dated August 29, 2022). On December 21, 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral
of the Sunset Date of Topic 848,&#x201d; which extends the period of time entities can utilize the reference rate reform relief guidance
under ASU 2020-04 from December 31, 2022 to December 31, 2024.&lt;/span&gt;&lt;/p&gt;

June 2016, the FASB issued ASU No. 2016-13, &#x201c;Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments,&#x201d;
and various subsequent amendments to the initial guidance (collectively, &#x201c;Topic 326&#x201d;). Topic 326 introduces an approach,
based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale
debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most
financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities
are required to apply the standard&#x2019;s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the
first reporting period in which the guidance is adopted. In November 2019, FASB issued ASU 2019-10, &#x201c;Financial Instruments &#x2013;
Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842),&#x201d; which defers the effective date of ASU
2016-13 for public companies that are considered smaller reporting companies (&#x201c;SRC&#x201d;) as defined by the Commission to fiscal
years beginning after December 15, 2022, including interim periods within those fiscal years. The adoption of these ASUs by the Company
during the fourth quarter of 2022 did not have a material impact to its financial statements. &lt;/span&gt;&lt;/p&gt;

and Hedging &#x2013; Contracts in Entity&#x2019;s Own Equity.&#x201d; ASU 2020-06 simplifies the accounting for convertible instruments
by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts
in an entity&#x2019;s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06
is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as an
SRC. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within
those fiscal years. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and disclosures.&lt;/span&gt;&lt;/p&gt;

Company has three remediation projects, which are currently in progress relating to our PFD, PFM and PFSG (closed locations) subsidiaries,
all within our discontinued operations. The Company divested PFD in 2008; however, the environmental liability of PFD was retained by
the Company upon the divestiture of PFD. These remediation projects principally entail the removal/remediation of contaminated soil and,
in most cases, the remediation of surrounding ground water. The remediation activities are closely reviewed and monitored by the applicable
state regulators.&lt;/span&gt;&lt;/p&gt;

representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our
credit facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate
all commitments to extend further credit. The Company&#x2019;s Revised Loan Agreement prohibits us from paying cash dividends on our Common
Stock without prior approval from our lender. The Company was not required to perform testing of the FCCR requirement in the first and
third quarters of 2022 pursuant to amendments as discussed above. Based on an amendment that the Company entered into with its lender

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
CARES Act, which was enacted on March 27, 2020, provides an Employee Retention Credit (&#x201c;ERC&#x201d;) for qualifying businesses keeping
employees on their payroll during the COVID-19 pandemic. The ERC was subsequently amended by the Taxpayer Certainty and Disaster Tax
Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended
the ERC availability and guidelines under the CARES Act. Following these amendments, the Company determined that it was eligible for
the ERC, and as a result of the foregoing legislations, is eligible to claim a refundable tax credit against the &lt;span id="xdx_906_ecustom--EmployeeRetentionCreditsDescription_c20210701__20210930_zpMLEQp7ShEl" title="Employee retention credits, description"&gt;Company&#x2019;s share

wages are limited to $&lt;span id="xdx_900_ecustom--QualifiedWagesLimitationUnderERCProgramAmount_c20210701__20210930_zcaCscB7ysnf" title="Qualified wages limitation under the ERC program"&gt;10,000&lt;/span&gt; per employee per calendar quarter in 2021 for a maximum allowable ERC per employee of $&lt;span id="xdx_907_ecustom--MaximumERCPerEmployee_c20210701__20210930_z2BTqB1hFrhl" title="Maximum ERC per employee"&gt;7,000&lt;/span&gt; per calendar
quarter in 2021. For purposes of the amended ERC, an eligible employer is defined as having experienced a significant (20% or more) decline
in gross receipts during one or more of the first three 2021 calendar quarters when compared to 2019.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;During
the third quarter of 2022, the Company determined it was eligible for the ERC and amended its third quarter 2021 employer payroll tax
filings claiming a refund from the U.S. Treasury in the amount of approximately $&lt;span id="xdx_902_eus-gaap--OtherNonoperatingIncome_pp0p0_c20210701__20210930__us-gaap--IncomeStatementLocationAxis__us-gaap--OtherNonoperatingIncomeExpenseMember_zPDqsI8PXdMj" title="Non-operating income"&gt;1,975,000&lt;/span&gt;. As there is no authoritative guidance under
U.S. GAAP on accounting for government assistance to for-profit business entities, we account for the ERC by analogy to International
Accounting Standard (&#x201c;IAS&#x201d;) 20, Accounting for Government Grants and Disclosure of Government Assistance. In accordance with
IAS 20, management determined it has reasonable assurance for receipt of the ERC and recorded the expected refund as other income (within
&#x201c;Other income (expense)&#x201d;) on the Company&#x2019;s Consolidated Statements of Operations and other receivables (within &#x201c;Prepaid
and other assets&#x201d;) on the Company&#x2019;s Consolidated Balance Sheets. For federal income tax purposes, this item was treated as
a reduction in payroll costs for 2021, the year in which the costs originated. This resulted in a timing difference for the benefit between
financial statement inclusion and tax inclusion between 2021 and 2022. This timing difference does not impact the Company&#x2019;s effective
tax rate.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;During
the fourth quarter of 2021, the Company sold PFM Poland resulting from its decision to cease all R&amp;amp;D activities under its Medical
Segment. Prior to the sale, the Company purchased Perma-Fix Medical LLC which was converted from PFMC, a wholly-owned subsidiary of PFM
Poland. Perma-Fix Medical LLC was treated as a disregarded entity for tax purposes, resulting in a realized tax loss of $&lt;span id="xdx_901_eus-gaap--IncomeTaxExpenseBenefit_pn3d_c20211001__20211231__us-gaap--TypeOfArrangementAxis__custom--PFMPolandMember_zKc8k4H8iXr9" title="Income Tax Expense (Benefit)"&gt;2,466,000&lt;/span&gt; from
uncollected payables. As a condition of the sale of PFM Poland, the Company forgave its receivables from PFM Poland resulting in a $&lt;span id="xdx_90D_eus-gaap--GainOrLossOnSaleOfStockInSubsidiary_c20211001__20211231__us-gaap--TypeOfArrangementAxis__custom--PFMPolandMember_zy9xVGGGXfi4" title="Gain (loss) on sale of stock in subsidiary"&gt;3,089,000&lt;/span&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable income. In conducting this
assessment, the Company considers projected future taxable income and ongoing tax planning strategies, then records a valuation allowance
to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized. As of September
30, 2021, the Company determined that it was more likely than not that it would be able to realize a portion of the deferred income tax
assets. As a result, a deferred income tax benefit in the amount of approximately $&lt;span id="xdx_903_eus-gaap--IncomeTaxReconciliationChangeInDeferredTaxAssetsValuationAllowance_c20210701__20210930_zuIGQ4N5vUla" title="Valuation allowance"&gt;2,351,000&lt;/span&gt; attributable to the valuation allowance
release on beginning of year deferred tax assets primarily related to U.S. Federal income taxes was realized in the three months ended
September 30, 2021. The Company had previously maintained a full valuation allowance against its net deferred income tax assets. The
Company continues to maintain a valuation allowance against certain state and foreign tax attributes that may not be realizable along
with the capital loss carryover generated during 2021 that it does not expect to realize.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;As of December 31, 2022, the Company assessed whether its deferred tax asset will more likely than not to be realized. This assessment
included both positive and negative available evidences, which included the Company&#x2019;s current contracts, cumulative loss, future
reversal of existing taxable differences, and overall prospect of future business and earnings. Based on the weight of these available
evidences, the Company concluded that it will more likely than not utilize its Federal and certain state net operating losses.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
global intangible low-taxed income (&#x201c;GILTI&#x201d;) provisions under the Tax Cuts and Jobs Act of 2017 (the &#x201c;TCJA&#x201d;)
require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign
subsidiary&#x2019;s tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore
has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the years ended December 31, 2022 and
2021. As the Canada and United Kingdom foreign subsidiaries are in loss positions for 2022, no GILTI inclusion is expected for these

March 27, 2020, the CARES Act was enacted and signed into law. The CARES Act included a number of income tax law changes, including modifications

net operating losses. The Company received forgiveness of its PPP Loan effective June 15, 2021 which was included in its Consolidated

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company made the strategic decision during the fourth quarter of 2021 to cease all R&amp;amp;D activities under its Medical Segment. The
Medical Segment conducted its activities through the Company&#x2019;s majority-owned Polish subsidiary, PFM Poland and PFM Poland&#x2019;s
wholly-owned subsidiary PFMC, a Delaware corporation. On December 30, 2021, the Company entered into a Sales of Shares Agreement (the
&#x201c;sales agreement&#x201d;) for its entire stock ownership (&lt;span id="xdx_90C_eus-gaap--EquityMethodInvestmentOwnershipPercentage_iI_pid_uPure_c20211230__us-gaap--TypeOfArrangementAxis__custom--SalesAgreementMember__srt--ScheduleOfEquityMethodInvestmentEquityMethodInvesteeNameAxis__custom--PFMLLCMember_zuBVTPCV2Esg" title="Ownership percentage"&gt;60.54%&lt;/span&gt;) of PFM Poland for notes receivable of approximately $&lt;span id="xdx_903_eus-gaap--NotesReceivableNet_iI_c20211230__us-gaap--TypeOfArrangementAxis__custom--SalesAgreementMember__srt--ScheduleOfEquityMethodInvestmentEquityMethodInvesteeNameAxis__custom--PFMLLCMember_zY6FockK3cpj" title="Notes receivable, amount"&gt;47,000&lt;/span&gt; (USD)
which was paid by the buyer in 2022. As condition precedent to the sales agreement, the Company released PFM Poland from unsatisfied
trade payables owed by PFM Poland to the Company totaling approximately $&lt;span id="xdx_90C_eus-gaap--AccountsPayableTradeCurrent_iI_c20211230__us-gaap--TypeOfArrangementAxis__custom--SalesAgreementMember__srt--ScheduleOfEquityMethodInvestmentEquityMethodInvesteeNameAxis__custom--PFMLLCMember_zwcTYq9DtBpc" title="Trade payables"&gt;2,537,000&lt;/span&gt; (USD). The Company ceased to have any continuing involvement
with PFM Poland.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Immediately
before the sales agreement was executed, the Company converted PFMC from a S Corporation to a limited liability company (Perm-Fix Medical
LLC or &#x201c;PFM LLC&#x201d;) and acquired the entire ownership from the majority-owned Polish subsidiary for $&lt;span id="xdx_902_ecustom--AcquiredPrice_iI_pid_c20221231__us-gaap--TypeOfArrangementAxis__custom--SalesAgreementMember_zkm78Fd9UbHb" title="Acquired price"&gt;10&lt;/span&gt;. The transaction was
deemed to be a common control transaction and all assets and liabilities were transferred using the historical carrying values in accordance
with guidance in ASC 805-50-25, &#x201c;Business Combinations, Related Issues, Recognition.&#x201d; The carrying amount of the non-controlling
interest was adjusted to reflect the change in the ownership of the subsidiary. As a result, approximately $&lt;span id="xdx_900_eus-gaap--MinorityInterest_iI_pid_c20221231__us-gaap--TypeOfArrangementAxis__custom--SalesAgreementMember_zz5xLwyMemRi" title="Non-controlling interest"&gt;1,004,000&lt;/span&gt; of the non-controlling

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;As
a result, effective December 30, 2021, PFM Poland was no longer a subsidiary of the Company and the Company deconsolidated the entity
from its consolidated financial statements in accordance with guidance in ASC 810-10-40, &#x201c;Consolidation, Overall, Derecognition.&lt;i&gt;&#x201d;
&lt;/i&gt;Accordingly, the December 31, 2021 Consolidated Balance Sheet did not in include balances for PFM due to the sale and deconsolidation
of PFM Poland. The Company&#x2019;s Consolidated Statements of Operations included results of its majority-owned Polish subsidiary for
the period through December 30, 2021.&lt;/span&gt;&lt;/p&gt;

(&#x201c;Defendants&#x201d;). The complaint alleges various claims, including a claim for negligence, negligent misrepresentation, equitable
indemnification and related business claims against all defendants related to alleged damages suffered by Tetra Tech in respect of certain
draft reports prepared by defendants at the request of the U.S. Navy as part of an investigation and review of certain whistleblower
complaints about Tetra Tech&#x2019;s environmental restoration at the Hunter&#x2019;s Point Naval Shipyard in San Francisco.&lt;/span&gt;&lt;/p&gt;

(&#x201c;Agreement&#x201d;). The NOT was received after work under the TOA was substantially completed and work under the TOA has since
been completed. CNL may terminate the TOA at any time for convenience.

connection with the termination of the TOA, including the bond as discussed above, against amounts owed to PF Canada for work performed
by PF Canada or its subcontractors. PF Canada continues to be in discussions with CNL to finalize the amounts due to PF Canada under
the TOA and continues to believe these amounts are due and payable to PF Canada.&lt;/span&gt;&lt;/p&gt;

be extended for one additional year, unless at least six months prior to the expiration of the Initial Term, we or the executive officer
provides written notice not to extend the terms of the Employment Agreement. Each Employment Agreement provides for annual base salary,
performance bonuses (as provided in the Management Incentive Plan (&#x201c;MIP&#x201d;) as approved by the Company&#x2019;s Compensation
Committee and Board) and other benefits commonly found in such agreement.&lt;/span&gt;&lt;/p&gt;

and accrued unused vacation time through the date of termination and any benefits due to the executive officer under any employee benefit
plan (the &#x201c;Accrued Amounts&#x201d;) plus any performance compensation payable pursuant to the MIP with respect to the fiscal year

without cause (including any such termination for &#x201c;good reason&#x201d; or without cause within 24 months after a Change in Control
(as defined in the agreement)), the Company will pay the executive officer the Accrued Amounts, two years of full base salary, and two
times the performance compensation (under the MIP) earned with respect to the fiscal year immediately preceding the date of termination
provided the performance compensation earned with respect to the fiscal year immediately preceding the date of termination has not been
paid. If performance compensation earned with respect to the fiscal year immediately preceding the date of termination has been made
to the executive officer, the executive officer will be paid an additional year of the performance compensation earned with respect to
the fiscal year immediately preceding the date of termination. If the executive terminates his employment for a reason other than for
good reason, the Company will pay to the executive an amount equal to the Accrued Amounts plus any performance compensation payable pursuant
to the MIP with respect to the fiscal year immediately preceding the date of termination.&lt;/span&gt;&lt;/p&gt;

there is a Change in Control (as defined in the agreement), all outstanding stock options to purchase common stock held by the executive

will immediately become exercisable in full commencing on the date of death, with such options exercisable for the lesser of the original
option term or twelve months from the date of the executive officer&#x2019;s death. In the event an executive officer terminates his employment

by the executive officer will immediately become exercisable in full commencing on the date of termination, with such options exercisable

payable with respect to a termination (other than Accrued Amounts) shall not be payable until the termination constitutes a &#x201c;separation
from service&#x201d; (as defined under Treasury Regulation Section 1.409A-1(h)).&lt;/span&gt;&lt;/p&gt;
