Two New Landfill Gas-to-Energy Facilities Commence Operation in Virginia

With More than 50 Existing Landfill Gas-to-Energy Projects, Allied Waste is a Leader in the Generation of Renewable Energy

Allied Waste Industries, Inc. (NYSE: AW), the second largest non-hazardous solid waste services company in the United States, today announced the commencement of operations of its two newest landfill gas-to-energy facilities, both located in Virginia.

The Brunswick County Landfill in Lawrenceville, Virginia is an 8-megawatt generating facility that has been developed with Richmond, Virginia-based Ingenco, which builds, owns and operates distributed generation facilities. The Brunswick County facility, which commenced operations in mid-October, will generate enough electricity to power over 5,000 homes.

The King & Queen County Landfill in Little Plymouth, Virginia is a 12-megawatt generating facility that also has been developed with Ingenco. The King & Queen County Landfill facility will generate enough electricity to power more than 7,500 homes. It is expected to commence operations by the end of the month.

Allied Waste currently has 52 landfill gas-to-energy projects underway, including 41 electric-generation plants, operating at facilities owned or operated by the company's subsidiaries across the country. The emission reduction achieved by Allied Waste's current projects nationwide is equal to removing approximately 2.6 million vehicles from the road each year, providing heat/power to approximately 240,000 homes, or receiving the benefits of planting 3.7 million acres of trees. In addition, the company has 17 projects in permitting or under construction.

"We are pleased to partner with Ingenco in two new Virginia gas-to-energy facilities," said Donald W. Slager, President and Chief Operating Officer for Allied Waste. "Allied Waste's current portfolio of more than 50 gas-to-energy facilities is performing well, and we are looking forward to bringing online several additional alternative-energy projects that are in various stages of approval and development. Innovative alternative energy projects such as these exemplify Allied Waste's commitment to our customers, our communities and to sound environmental stewardship, and thus are under consideration at dozens of our landfills nationwide."

Methane gas occurs naturally at landfills as a by-product of the decomposition of organic materials. Gas is collected, dried and used as a fuel source in a variety of projects from electrical generation to industrial boiler fuel to wastewater evaporation. Over 430 such projects have been registered with the U.S. Environmental Protection Agency's Landfill Methane Outreach Program.
