Casella Waste Systems, Inc. Program to Divest Non-Strategic Operations Reaches $20 Million Mark in Divested Revenues With Buffalo Market Exit

Casella Waste Systems, Inc. (NASDAQ: CWST) announced today that the Company has sold its Buffalo, New York transfer station, hauling operation and related equipment to the principals of Modern Landfill, Inc. for approximately $5.5 million in net proceeds. With the sale, the Company substantially completed its targeted divestiture program with divested revenues of approximately $20.0 million from non-strategic assets.

"In March 2007, we laid out a plan to divest, swap, restructure, or close underperforming and non-strategic operations," said John W. Casella, chairman and chief executive officer of Casella Waste Systems. "With the sale of the Buffalo facilities and the Holliston facility in April 2007, we have divested approximately $20.0 million of annual revenues from low margin operations that do not fit our long-term strategic plan."

The Buffalo transfer station and hauling company reported third party revenues of $9.2 million for the twelve months ended April 30, 2007 and $2.4 million for the three months ended July 31, 2007.
