April 24th: Tour of Covanta Fairfax Incorporated’s Energy-from-Waste Facility, Lorton, Virginia

The I-95 Energy/Resource Recovery Facility, operating as Covanta Fairfax, Inc, began commercial operation in June 1990.  It is Covanta Energy's largest facility, processing more than 3,000 tons per day of municipal solid waste for a population of more than 900,000 in the Washington, D.C. suburbs of Fairfax County, Virginia. The facility sells over 80 megawatts of renewable energy to Dominion Virginia Power Company, enough energy to meet the needs of over 80,000 homes.  It is the first Covanta Energy facility to have a non-ferrous metal recovery system.  The facility incorporates four 750+ tons-per-day waterwall furnaces with Martin reverse-reciprocating grates and ash handling systems.  Air pollution control equipment includes semi-dry flue gas scrubbers injecting lime, fabric filter bag houses, nitrogen oxide control system, mercury control system, and a continuous emissions monitoring (CEM) system. During lunch, our host will describe the landfill's energy and environmental conservation initiatives.  The landfill incorporates a bank of generators fueled by landfill gas and provides additional landfill gas to the nearby waste plant on Route One.
