<p style="margin:0pt 0pt 12.0pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">CASELLA WASTE SYSTEMS, INC.
ANNOUNCES PRELIMINARY RESULTS FOR FISCAL YEAR 2007 FIRST QUARTER</font></b></p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt;text-indent:18.0pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">RUTLAND,
VERMONT </font></b>(August 16, 2006) &#151; Casella Waste Systems, Inc.
(Nasdaq: CWST), a regional, non-hazardous solid waste services company, today
said that the quarter&#146;s overall performance fell short of expectations and the
company will likely report a net earnings per share (EPS) loss of $(0.02) to
$(0.04). The company said that its overall company revenues for its first
quarter of fiscal year 2007 are on track, with the exception being its South
Eastern region.</p>

<p style="margin:0pt 0pt 12.0pt;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The company also
said it expects its earnings before interest, taxes, depreciation and
amortization (EBITDA*) for the fiscal year ending April 30, 2007 to be in a
range of $113 million to $117 million.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The company
characterized its first quarter results as the cumulative impact of the
following key factors:</font></p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt 36.0pt;text-indent:-18.0pt;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font>Historical
record rainfalls slowed seasonal construction activity in the north eastern
U.S.; the company reported abnormally low roll-off container activity on a
year-over-year basis in the Massachusetts market. For the balance of the
company&#146;s solid waste markets, roll-off pulls were flat on a year-over-year
basis.</p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt 36.0pt;text-indent:-18.0pt;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font>The
company&#146;s regional landfills incurred higher than normal leachate treatment and
transportation costs, as the volume of rainfall increased leachate production.
The landfills also saw a material increase in weather-related maintenance
costs.</p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt 36.0pt;text-indent:-18.0pt;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font>The
company&#146;s Worcester, MA landfill closure project faced a weaker-than-expected
pricing environment due to the deep per-ton discounting of airspace at a
competing landfill preparing for closure. The company chose not to sacrifice
its airspace at Worcester at a lower revenue rate; as a result, the Worcester
facility&#146;s contribution did not offset the loss of its Brockton, MA landfill
closure project&#146;s contribution on a year-over-year basis.</p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt 36.0pt;text-indent:-18.0pt;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font>Lower
volumes at the company&#146;s Hardwick, MA landfill.</p>

general and administration expenses as a percent of revenue.</p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt 36.0pt;text-indent:-18.0pt;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font>Plastic
commodities, the only commodity without effective hedges, suffered a
precipitous drop in pricing.</p>

<p style="font-family:Times New Roman;font-size:10.0pt;margin:0pt 0pt 12.0pt;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The company will
host a conference call with investors on August 17, 2006 at 9:00 a.m. ET.

<p style="margin:0pt 0pt 12.0pt;text-autospace:none;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The company expects to release its full first quarter

<p style="margin:0pt 0pt 12.0pt;text-autospace:none;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition to disclosing financial results prepared
in accordance with Generally Accepted Accounting Principles (GAAP), we also
disclose free cash flow and earnings before interest, taxes, depreciation and
amortization (EBITDA), which are non-GAAP measures.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-autospace:none;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">These measures are provided because we understand that
certain investors use this information when analyzing the financial position of
the solid waste industry, including us. Historically, these measures have been
key in comparing operating efficiency of publicly traded companies in the solid
waste industry, and assist investors in measuring our ability to meet capital
expenditure and working capital requirements. For these reasons we utilize
these non- GAAP metrics to measure our performance at all levels. These
measures do not represent, and should not be considered as alternatives to cash
provided by operating activities as determined in accordance with GAAP. Moreover,
these measures do not necessarily indicate whether cash flow will be sufficient
for such items as working capital or capital expenditures, or to react to
changes in our industry or to the economy generally. Because these measures are
not calculated by all companies in the same fashion, they may not be comparable
to similarly titled measures reported by other companies.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-autospace:none;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">Safe Harbor Statement</font></b></p>

<p style="margin:0pt 0pt 12.0pt;text-autospace:none;text-indent:18.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Certain matters discussed in this press release are &#147;forward-looking
statements&#148; intended to qualify for the safe harbors from liability established
by the Private Securities Litigation Reform Act of 1995. These forward-looking
statements can generally be identified as such by the context of the
statements, including words such as the Company &#147;believes,&#148; &#147;anticipates,&#148; &#147;expects&#148;
or words of similar import. Similarly, statements that describe the Company&#146;s
future plans, objectives or goals are forward-looking statements. Such
forward-looking statements, and all phases of our operations, involve a number
of risks and uncertainties, any one or more of which could cause actual results
to differ materially from those described in our forward-looking statements.
Such risks and uncertainties include or relate to, among other things: our
financial results above are preliminary; we may be unable to make acquisitions
and otherwise develop additional disposal capacity; continuing weakness in
general economic conditions and weather conditions may affect our revenues; we
may be required to incur capital expenditures in excess of our estimates; and
fluctuations in the commodity pricing of our recyclables may make it more
difficult for us to predict our results of operations. Other factors which
could materially affect such forward-looking statements can be found in our
periodic reports filed with the Securities and Exchange Commission, including
the Risk Factors section in our Form 10-K for the fiscal year ended April 30,
2006.</font></p>
