RUTLAND, VT -- (Marketwire) -- 08/03/12 -- Casella Waste Systems, Inc. (NASDAQ: CWST), a regional vertically-integrated solid waste, recycling and resource management services company, announced today that it signed a purchase and sale agreement to sell its Maine Energy Recovery facility ("MERC") to the City of Biddeford, ME ("Biddeford").

At a special meeting on Tuesday, July 31, 2012 Biddeford's nine-member council voted to enter into the purchase and sale agreement for MERC, and the agreement was subsequently executed by the company and Biddeford on Wednesday, August 1, 2012. As per the purchase and sale agreement, Biddeford will pay the company total consideration of $6.65 million over 20 years, enter into a new 10 year waste handling agreement, and enter into a new 10 year recycling collection agreement.

The sale of the facility is set to close by November 15, 2012, with the closing contingent upon certain conditions precedent for the buyer and the seller. These conditions precedent include the company successfully receiving a final permit modification at the Juniper Ridge Landfill in Old Town, ME to accept municipal solid waste (MSW). Currently, Juniper Ridge Landfill may only accept MSW as a by-pass stream from waste-to-energy facilities.

"With the signing of this purchase and sale agreement I believe that we have reached a win-win outcome for both the company and the City of Biddeford," said John W. Casella, chairman and CEO of Casella Waste Systems. "Biddeford had approached us several times over the past ten years to find a solution to shut down the 25-year old waste-to-energy facility to redevelop their downtown area. Given current low energy prices and our belief that a successful resource management strategy combines waste reduction, an effective recycling solution and waste disposal in a low-emission landfill, we have structured a transaction that is favorable for our shareholders, while helping the community to meet its long-term solid waste objectives through 10 year waste handling and Zero-Sort® Recycling contracts."
