Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation and Consolidation. These consolidated financial statements include the accounts of Aemetis. Additionally, we consolidate all entities in which we have a controlling financial interest. A controlling financial interest is usually obtained through ownership of a majority of the voting interests. However, an enterprise must consolidate a variable interest entity (“VIE”) if the enterprise is the primary beneficiary of the VIE, even if the enterprise does not own a majority of the voting interests. The primary beneficiary is the party that has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. ABGL was assessed to be a VIE and through the Company’s ownership interest in all of the outstanding common stock, the Company has been determined to be the primary beneficiary and accordingly, the assets, liabilities, and operations of ABGL are consolidated into those of the Company. All intercompany balances and transactions have been eliminated in consolidation. The accompanying consolidated condensed balance sheet as of September 30, 2022, the consolidated condensed statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2022 and 2021, the consolidated condensed statements of cash flows for the nine months ended September 30, 2022 and 2021, and the consolidated condensed statements of stockholders’ deficit for the three and nine months ended September 30, 2022 and 2021 are unaudited. The consolidated condensed balance sheet as of December 31, 2021 was derived from the 2021 audited consolidated financial statements and notes thereto. The consolidated condensed financial statements in this report should be read in conjunction with the 2021 audited consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2021. The accompanying consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of Company’s management, the unaudited interim consolidated condensed financial statements as of and for the three and nine months ended September 30, 2022 and 2021 have been prepared on the same basis as the audited consolidated statements as of and for the year ended December 31, 2021 and reflect all adjustments, consisting primarily of normal recurring adjustments, necessary for the fair presentation of its statement of financial position, results of operations and cash flows. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the operating results for any subsequent quarter, for the full fiscal year or any future periods.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, revenues, and expenses during the reporting period. To the extent there are material differences between these estimates and actual results, the Company’s consolidated financial statements will be affected.
Revenue [Policy Text Block] | Revenue Recognition. We derive revenue primarily from sales of ethanol and related co-products in North America, and biodiesel and refined glycerin in India pursuant to supply agreements and purchase order contracts. We assessed the following criteria under the Accounting Standards Codification (“ASC”) 606 guidance: (i) identify the contracts with customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when the entity satisfies the performance obligations. California Ethanol: Until May 13, 2020, we sold all our ethanol to J.D. Heiskell & Co. (“J.D. Heiskell”) under the Working Capital and Purchasing Agreement (the “J.D. Heiskell Purchasing Agreement”). On May 13, 2020, we entered into an amendment to the Corn Procurement and Working Capital Agreement with J.D. Heiskell (the “Corn Procurement and Working Capital”), under the terms of which we buy all corn from J.D. Heiskell and sell all WDG and corn oil we produce to J.D. Heiskell. Following May 13, 2020 and until October, 2021, we sold the majority of our fuel ethanol production to one customer, Kinergy Marketing, LLC (“Kinergy”), through individual sales transactions. We terminated the Ethanol Marketing Agreement with Kinergy as of September 30, 2021. Effective October 1, 2021, we entered into Fuel Ethanol Purchase and Sale Agreement with Murex LLC (“Murex”), in which we sell all our ethanol to Murex. Given the similarity of the individual sales transactions with Kinergy and Murex, we have assessed them as a portfolio of similar contracts. The performance obligation is satisfied by delivery of the physical product to one of our customer’s contracted trucking companies. Upon delivery, the customer has the ability to direct the use of the product and receive substantially all of its benefits. The transaction price is determined based on daily market prices negotiated by Kinergy and Murex for ethanol and by our marketing partner A.L. Gilbert Company (“A.L. Gilbert”) for WDG. The transaction price is allocated to one performance obligation. The below table shows our sales in our California Ethanol segment by product category:
|  | For the three months ended September 30, |  |  | For the nine months ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Ethanol and high-grade alcohol sales |  | $ | 44,673 |  |  | $ | 39,131 |  |  | $ | 130,224 |  |  | $ | 111,220 |
Wet distiller's grains sales |  |  | 13,003 |  |  |  | 8,919 |  |  |  | 39,669 |  |  |  | 30,584 |
Other sales |  |  | 3,231 |  |  |  | 1,782 |  |  |  | 8,947 |  |  |  | 5,086 |
|  | $ | 60,908 |  |  | $ | 49,832 |  |  | $ | 178,840 |  |  | $ | 146,890 |
We have elected to adopt the practical expedient that allows for ignoring the significant financing component of a contract when estimating the transaction price when the transfer of promised goods to the customer and customer payment for such goods are expected to be within one year of contract inception. Further, we have elected to adopt the practical expedient in which incremental costs of obtaining a contract are expensed when the amortization period would otherwise be less than one year. We also assessed principal versus agent criteria as we buy our feedstock from our customers and process and sell finished goods to those customers in certain contractual agreements. For our California Ethanol segment, we buy corn as feedstock for the production of ethanol, from our working capital partner J.D. Heiskell. Prior to May 13, 2020, we sold all our ethanol, WDG, and corn oil to J.D. Heiskell and we bought all our corn to process into ethanol from J.D. Heiskell. After May 13, 2020, we sold most of our fuel ethanol to one customer, Kinergy, and sold all WDG and corn oil to J.D. Heiskell. During the second quarter of 2021, we signed a biofuels offtake agreement with Murex, and beginning on October 1, 2021 we sold all our fuel ethanol to Murex. We only have customer relationships with Kinergy and Murex, hence the principal and agent criteria are not applied. However, we are still buying corn and selling WDG and corn oil to J.D.Heiskell. We analyzed the principal versus agent relationship criteria below. We consider the purchase of corn as a cost of goods sold and the sale of WDG and, corn oil, upon trucks leaving the Keyes Plant, as revenue on the basis that (i) we control and bear the risk of gain or loss on the processing of corn which is purchased at market prices into ethanol and (ii) we have legal title to the goods during the processing time. The pricing for both WDG and corn oil is set independently. Revenues from WDG and corn oil are billed net of the related transportation and marketing charges. The transportation component is accounted for in cost of goods sold and the marketing component is accounted for in sales, general and administrative expense. Transportation and marketing charges are known within days of the transaction and are recorded at the actual amounts. We have elected an accounting policy under which these charges have been treated as fulfillment activities provided after control has transferred. As a result, these charges are recognized in cost of goods sold and selling, general and administrative expenses, respectively, when revenue is recognized. Revenues are recorded at the gross invoiced amount. Hence, we are the principal in California Ethanol segment where our customer and vendor may be the same. Dairy Renewable Natural Gas: All of our Dairy Renewable Natural Gas segment revenues during the three and nine months ended September 30, 2022 and 2021 were from sales of biogas to the Keyes Plant for use in boilers. This resulted in lowering the carbon intensity of the Keyes Plant and increased revenues on ethanol sold through the California Ethanol segment. These revenues have been eliminated once consolidated. Refer to Note 10 Segment Information for the unconsolidated revenue of our Dairy Renewable Natural Gas segment. India Biodiesel: We sell products pursuant to purchase orders (written or verbal) or by contract with governmental or international parties, in which performance is satisfied by delivery and acceptance of the physical product. Given that the contracts are sufficiently similar in nature, we have assessed these contracts as a portfolio of similar contracts as allowed under the practical expedient. Doing so does not result in a materially different outcome compared to individually accounting for each contract. All domestic and international deliveries are subject to certain specifications as identified in contracts. The transaction price is determined daily based on reference market prices for biodiesel, refined glycerin, and palm fatty acid distillate net of taxes. Transaction price is allocated to one performance obligation. The below table shows our sales in our India Biodiesel Segment by product category:
|  | For the three months ended September 30, |  |  | For the nine months ended September 30, 2022 |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Biodiesel sales |  | $ | 10,828 |  |  | $ | - |  |  | $ | 10,828 |  |  | $ | 465 |
Other sales |  |  | 95 |  |  |  | 63 |  |  |  | 113 |  |  |  | 231 |
|  | $ | 10,923 |  |  | $ | 63 |  |  | $ | 10,941 |  |  | $ | 696 |
In India, we also assessed principal versus agent criteria as we buy our feedstock from our customers and process and sell finished goods to those same customers in certain contractual agreements. In those cases, we receive the legal title to feedstock from our customers once it is on our premises. We control the processing and production of biodiesel based on contract terms and specifications. The pricing for both feedstock and biodiesel is set independently. We hold the title and risk to biodiesel according to agreements when we enter into in these situations. Hence, we are the principal in India sales scenarios where our customer and vendor may be the same.
Cost of Goods and Service [Policy Text Block] | Cost of Goods Sold. Cost of goods sold includes those costs directly associated with the production of revenues, such as raw material consumed, factory overhead and other direct production costs. During periods of idle plant capacity, costs otherwise charged to cost of goods sold are reclassified to selling, general and administrative expense.
Shipping and Handling Costs [Policy Text Block] | S hipping and Handling Costs. Shipping and handling costs are classified as a component of cost of goods sold in the accompanying consolidated statements of operations.
Receivable [Policy Text Block] | Accounts Receivable. The Company sells ethanol and WDG through third-party marketing arrangements generally without requiring collateral and high-grade alcohol directly to customers on a variety of terms including advanced payment terms, based on the size and creditworthiness of the customer. DCO is marketed and sold to A.L. Gilbert and other customers under the J.D. Heiskell Purchasing Agreement. The Company sells CDS directly to customers on standard 30 day payment terms. The Company sells biodiesel, glycerin, and processed natural oils to a variety of customers and may require advanced payment based on the size and creditworthiness of the customer. Usually, invoices are due within 30-days on net terms. Accounts receivables consist of product sales made to large creditworthy customers. Trade accounts receivable are presented at original invoice amount, net of any allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for balances that appear to have specific collection issues. The collection process is based on the age of the invoice and requires attempted contacts with the customer at specified intervals. If, after a specified number of days, the Company has been unsuccessful in its collection efforts, a bad debt allowance is recorded for the balance in question. Delinquent accounts receivables are charged against the allowance for doubtful accounts once un-collectability has been determined. The factors considered in reaching this determination are the apparent financial condition of the customer and the Company’s success in contacting and negotiating with the customer. If the financial condition of the Company’s customers were to deteriorate, additional allowances may be required. We reserved $1.4 million in the allowances for doubtful accounts as of December 31, 2021 and wrote off the balances as uncollectible during the second quarter of 2022.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents. The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company maintains cash balances at various financial institutions domestically and abroad. The Federal Deposit Insurance Corporation insures domestic cash accounts. The Company’s accounts at these institutions may at times exceed federally insured limits. The Company has not experienced any losses in such accounts.
Inventory, Policy [Policy Text Block] | Inventories. Finished goods, raw materials, and work-in-process inventories are valued using methods which approximate the lower of cost (first-in, first-out) or net realizable value (“NRV”). Distillers’ grains and related products are stated at NRV. In the valuation of inventories, NRV is determined as estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
Consolidation, Variable Interest Entity, Policy [Policy Text Block] | Variable Interest Entities. We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests in is considered a variable interest entity (“VIE”). We consolidate VIEs when we are the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (1) has the power to make decisions that most significantly affect the economic performance of the VIE; and (2) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Periodically, we assess whether any changes in our interest or relationship with the entity affects our determination of whether the entity is still a VIE and, if so, whether we are the primary beneficiary. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable U.S. GAAP.
Property, Plant and Equipment, Policy [Policy Text Block] | Property, Plant and Equipment. Property, plant, and equipment are carried at cost less accumulated depreciation after assets are placed in service and are comprised primarily of plant and buildings, furniture, machinery, equipment, land, and biogas dairy digesters. Capital expenses for in-process project are accumulated in construction in progress and will be capitalized and depreciated once the capital projects are finished and are in service. The Company’s plant in Goodland, Kansas (the ”Goodland Plant”) is partially completed and is not ready for operation. It is the Company’s policy to depreciate capital assets over their estimated useful lives using the straight-line method. The Company evaluates the recoverability of long-lived assets with finite lives in accordance with ASC Subtopic 360-10-35 Property Plant and Equipment—Subsequent Measurements, which requires recognition of impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. When events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable, based on estimated undiscounted cash flows, the impairment loss would be measured as the difference between the carrying amount of the assets and its estimated fair value. The Company has not recorded any impairment during the three and nine months ended September 30, 2022 and 2021.
California Energy Commission Low Carbon Fuel Production Program [Policy Text Block] | California Energy Commission Low-Carbon Fuel Production Program. The Company has been awarded $4.2 million in matching grants from the California Energy Commission Low-Carbon Fuel Production Program (“LCFPP”). The LCFPP grant reimburses the Company for costs to design, procure, and install processing facility to clean-up, measure and verify negative-carbon intensity dairy renewable natural gas fuel at the production facility in Keyes, California. The Company has received $3.8 million from the LCFPP as of September 30, 2022, as reimbursement for actual costs incurred. Due to the uncertainty associated with the approval process under the grant program, the Company recognized the grant as a reduction of costs in the period when payment is received.
California Department of Food and Agriculture Dairy Digester Research and Development Grant [Policy Text Block] | California Department of Food and Agriculture Dairy Digester Research and Development Grant. In 2019, the Company was awarded $3.2 million in matching grants from the California Department of Food and Agriculture (“CDFA”) Dairy Digester Research and Development program. The CDFA grant reimburses the Company for costs required to permit and construct two of the Company’s biogas capture systems under contract with central California dairies. The Company received all the awarded grant proceeds as of the second quarter of 2021. In October 2020, the Company was awarded $7.8 million in matching grants from the CDFA Dairy Digester Research and Development program. The CDFA grant reimburses the Company for costs required to permit and construct six of the Company’s biogas capture systems under contract with central California dairies. The Company has received $2.3 million from the CDFA 2020 grant program as of September 30, 2022, as reimbursement for actual costs incurred. Due to the uncertainty associated with the approval process under the grant program, the Company recognized the grant as a reduction of costs in the period when payment is received
California Energy Commission Low Carbon Advanced Ethanol Grant Program [Policy Text Block] | California Energy Commission Low Carbon Advanced Ethanol Grant Program. In May 2019, the Company was awarded the right to receive reimbursements from the California Energy Commission Community-Scale and Commercial-Scale Advanced Biofuels Production Facilities grant under the Alternative and Renewable Fuel and Vehicle Technology Program in an amount up to $5.0 million (the “CEC Reimbursement Program”) in connection with the Company’s expenditures toward the development of the Riverbank Cellulosic Ethanol Facility. To comply with the guidelines of the CEC Reimbursement Program, the Company must make a minimum of $7.9 million in matching contributions to the Riverbank project. The Company receives funds under the CEC Reimbursement Program for actual expenses incurred up to $5.0 million as long as the Company makes the minimum matching contribution. Given that the Company has not made the minimum matching contribution, the grant for reimbursement of capital expenditures of $1.7 million is presented with long-term liabilities as of September 30, 2022, and December 31, 2021. Due to the uncertainty associated with meeting the minimum matching contribution, the reimbursement will be recognized when the Company makes the minimum matching contribution.
U.S. Department of Food and Agriculture Forest Service Grant [Policy Text Block] | U.S. Department of Food and Agriculture Forest Service Grant. Aemetis Advanced Products Keyes (“AAPK”) has been awarded $245 thousand in matching grants from the U.S. Department of Food and Agriculture Forest Service (“US Forest Service”) under the Wood Innovation and Community Wood program. The grant reimburses the Company for continued development of technologies and processes to valorize forest waste for the production of cellulosic ethanol. AAPK has received $73 thousand from the US Forest Service as reimbursement for actual allowable program costs incurred through September 30, 2022.
California Energy Commission Grant For Solar Microgrid DSC and Battery Backup System [Policy Text Block] | California Energy Commission Grant for Solar Microgrid, DSC and Battery Backup System. Aemetis Advanced Fuels Keyes (“AAFK”) has been awarded an $8.0 million grant to design, construct and commission a grid-connected 1.56 MW photovoltaic microgrid and 1.25MW/2.5MWh Battery Energy Storage System integrated with an artificial intelligence-driven distributed control system (DCS). The grant requires $1.6 million in matching contribution in which the Company has made. AAFK received $3.9 million in grant funds from this program as reimbursement for actual expenditures incurred through September 30, 2022. Due to the uncertainty associated with the approval process under the grant program, the Company recognized the grant as a reduction of costs in the period when payment is received.
California Department of Forestry and Fire Protection Grant [Policy Text Block] | California Department of Forestry and Fire Protection Grant. AAPK has been awarded $2 million in matching grants from the CAL FIRE Business and Workforce Development Grant Program (“CAL Fire”) in May 2022. This CAL Fire grant program reimburses AAPK for costs to design, construct, and commission a 2 million gallon per year cellulosic ethanol facility that will convert conifer biomass from forested regions of the Sierra Nevada into an ultra‐low carbon biofuel derived from 100% forest biomass (“CAL Fire Conversion Program”). AAPK must contribute $5.8 million in cost share contributions to the project to receive grant proceeds. AAPK has received no grant funds from the CAL Fire Conversion Program as reimbursement for actual costs through September 30, 2022
California Department of Forestry and Fire Protection Grant 2 [Policy Text Block] | California Department of Forestry and Fire Protection Grant. AAPK has been awarded $500 thousand in grants from CAL Fire in May 2022. This CAL Fire grant program reimburses AAPK for costs to advance a new‐to‐the world technology that circumvents current limitations surrounding the extraction of cellulosic sugars by pioneering a novel route for deconstructing woody biomass using ionic liquids (“CAL Fire Extraction Program”). AAPK has received no grant funds from the CAL Fire Extraction Program as reimbursement for actual costs through September 30, 2022
United States Forest Service Community Wood Grant [Policy Text Block] | U.S Forest Service Community Wood Grant. Aemetis Advanced Products Riverbank (“AAPR”) has been awarded $642 thousand in matching grants from the U.S Forest Service Wood Innovations Program (“USFS”) in May 2022. The USFS grant program reimburses AAPR for costs to design, construct, and commission a plant to produce cellulosic ethanol using preliminary research and development in partnership with the Joint Bioenergy Institute (JBEI). USFS grant funds will be used to complete the FEL-3 design phase of the entire process, construct a biomass pretreatment unit to extract sugars at the Aemetis Riverbank site and ferment sugars into ethanol at the Keyes Plant. AAPR must contribute $2.4 million in cost share contributions to the project to receive grant proceeds. AAPK has received no grant funds from the USFS grant program as reimbursement for actual costs through September 30, 2022
United States Department of Biofuel Producer Program Grant [Policy Text Block] | USDA’s Biofuel Producer Program Grant. During the second quarter of 2022, a grant in the amount of $14.2 million was received from the USDA’s Biofuel Producer Program, created as part of the CARES Act, to compensate biofuel producers who experienced market losses due to the COVID-19 pandemic. This was recorded in the other expense (income) section of the Consolidated Statements of Operations and Comprehensive Loss.
California Energy Commission Grant for Mechanical Vapor Recompression System [Policy Text Block] | California Energy Commission Grant for Mechanical Vapor Recompression System. Aemetis Advanced Fuels Keyes (“AAFK”) has been awarded a $6.0 million grant to design, construct and commission a mechanical vapor recompression (MVR) system. The additional evaporation stages will eliminate natural gas consumption and related greenhouse gas emissions in the evaporation portion of the process by installing metering equipment and software to monitor and optimize the plant’s energy consumption. The MVR system will compress vapor to a higher pressure and temperature so that it can be recycled multiple times as steam heat in the evaporation process, which will dramatically reduce natural gas use. The grant requires $5.3 million in matching contributions. AAFK has received no grant funds from this program as reimbursement for actual expenditures incurred through September 30, 2022. Due to the uncertainty associated with the approval process under the grant program, the Company will recognize future grant proceeds received as a reduction of costs in the period when payment is received.
Earnings Per Share, Policy [Policy Text Block] | Basic and Diluted Net Loss per Share. Basic net loss per share is computed by dividing net loss attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted net loss per share reflects the dilution of common stock equivalents such as options, convertible preferred stock, debt, and warrants to the extent the impact is dilutive. As the Company incurred net losses for the three and nine months ended September 30, 2022 and 2021, potentially dilutive securities have been excluded from the diluted net loss per share computations as their effect would be anti-dilutive. The following table shows the number of potentially dilutive shares excluded from the diluted net loss per share calculation as of September 30, 2022 and 2021:
|  | As of |
|  | September 30, 2022 |  |  | September 30, 2021 |
Series B preferred (post split basis) |  |  | 127 |  |  |  | 129 |
Common stock options and warrants |  |  | 5,064 |  |  |  | 3,929 |
Debt with conversion feature at $30 per share of common stock |  |  | 1,256 |  |  |  | 1,280 |
Total number of potentially dilutive shares excluded from the diluted net (loss) per share calculation |  |  | 6,447 |  |  |  | 5,338 |
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income (Loss). ASC 220 Comprehensive Income (Loss) requires that an enterprise report, by major components and as a single total, the change in its net assets from non-owner sources. The Company’s other comprehensive loss and accumulated other comprehensive loss consists solely of cumulative currency translation adjustments resulting from the translation of the financial statements of its foreign subsidiary. The investment in this subsidiary is considered indefinitely invested overseas, and as a result, deferred income taxes are not recorded related to the currency translation adjustments.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation/Transactions. Assets and liabilities of the Company’s non-U.S. subsidiary that operates in a local currency environment, where that local currency is the functional currency, are translated into U.S. dollars at exchange rates in effect at the balance sheet date and the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive loss. Income and expense accounts are translated at average exchange rates during the year. Transactional gains and losses from foreign currency transactions are recorded in other (income) expense, net.
Segment Reporting, Policy [Policy Text Block] | Segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company further evaluates its operating segments to determine its reportable segments. Aemetis recognizes three reportable segments “California Ethanol”, “Dairy Renewable Natural Gas”, and “India Biodiesel.” The “California Ethanol” reportable segment includes the Company’s 65 million gallon per year Keyes plant and the adjacent land leased for the production of CO₂. The “Dairy Renewable Natural Gas” reportable segment include, the dairy digesters, pipeline and gas condition hub for the production of biogas from dairies near Keyes, California. The “India Biodiesel” reportable segment includes the Company’s 50 million gallon per year nameplate capacity biodiesel manufacturing Kakinada Plant, the administrative offices in Hyderabad, India, and the holding companies in Nevada and Mauritius. The Company’s biodiesel is marketed and sold primarily to customers in India through brokers and by the Company directly. The Company has additional operating segments that were determined not to be reportable segments, including the Carbon Zero 1 facility in Riverbank, the Goodland Plant in Kansas and the research and development facility in Minnesota. Refer to the “All Other” category.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments. Financial instruments include accounts receivable, accounts payable, accrued liabilities, current and non-current portion of subordinated debt, notes receivable, notes payable, Series A preferred units, and long-term debt. Due to the unique terms of our notes payable and long-term debt and the financial condition of the Company, the fair value of the debt is not readily determinable. The fair value determined using level 3 inputs, of all other current financial instruments is estimated to approximate carrying value due to the short-term nature of these instruments.
Share-Based Payment Arrangement [Policy Text Block] | Share-Based Compensation. The Company recognizes share-based compensation expense in accordance with ASC 718 Stock Compensation requiring the Company to recognize expenses related to the estimated fair value of the Company’s share-based compensation awards at the time the awards are granted, adjusted to reflect only those shares that are expected to vest.
Commitments and Contingencies, Policy [Policy Text Block] | Commitments and Contingencies. The Company records and/or discloses commitments and contingencies in accordance with ASC 450 Contingencies. ASC 450 applies to an existing condition, situation or set of circumstances involving uncertainty as to possible loss that will ultimately be resolved when one or more future events occur or fail to occur.
Convertible Instruments [Policy Text Block] | Convertible Instruments. The Company evaluates the impacts of convertible instruments based on the underlying conversion features. Convertible instruments are evaluated for treatment as derivatives that could be bifurcated and recorded separately. Any beneficial conversion feature is recorded based on the intrinsic value difference at the commitment date.
Debt, Policy [Policy Text Block] | Debt Modification Accounting. The Company evaluates amendments to its debt in accordance with ASC 470-50 Debt–Modification and Extinguishments for modification and extinguishment accounting. This evaluation includes comparing the net present value of cash flows of the new debt to the old debt to determine if changes greater than 10 percent occurred. In instances where the net present value of future cash flows changed more than 10 percent, the Company applies extinguishment accounting and determines the fair value of its debt based on factors available to the Company. For a complete summary of the Company’s significant accounting policies, please refer to the Company’s audited financial statements and notes thereto for the years ended December 31, 2021 and 2020 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 10, 2022.
Research and Development Expense, Policy [Policy Text Block] | Research and Development. Research and development costs are expensed as incurred, unless they have alternative future uses to the Company.
