CASELLA WASTE SYSTEMS, INC. ANNOUNCES CONVERSION AND REMARKETING

OF A PORTION OF FAME SOLID WASTE DISPOSAL REVENUE BONDS

RUTLAND, VERMONT (January 11, 2012) — Casella Waste Systems, Inc. (NASDAQ: CWST), a regional solid waste, recycling and resource management services company, announced today that it intends to convert the interest rate period on, and remarket, $21.4 million aggregate principal amount of Finance Authority of Maine Solid Waste Disposal Revenue Bonds (Casella Waste Systems, Inc. Project) Series 2005 (the “Bonds”).  The Bonds were originally issued on December 28, 2005 and have a final maturity of January 1, 2025.

Following a mandatory tender for $21.4 million of the $25.0 million aggregate principal amount of Bonds currently outstanding, and satisfaction of certain conditions, the tendered Bonds are expected to be converted from a weekly interest rate period to a 5 year fixed term interest rate period and will include additional covenants and credit support for the benefit of holders of those converted Bonds, including guarantees by certain subsidiaries of Casella.  Upon conversion to a 5 year fixed term interest rate period, the converted Bonds will not be secured by a letter of credit.  The converted Bonds will be remarketed on February 1, 2012.  The remaining $3.6 million of outstanding bonds, the proceeds of which were used to finance assets at Casella’s Maine Energy Recovery Company, will remain in a weekly interest rate period and will remain secured by a letter of credit issued by Bank of America, N.A.

The Bonds are being offered only to qualified institutional buyers as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”).

The Bonds have not been and will not be registered under the Securities Act and will be offered and sold pursuant to an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy the Bonds, nor shall there be any sale of the Bonds in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.  This notice is being issued pursuant to and in accordance with Rule 135c under the Securities Act.
