The SEMASS Resource Recovery Facility provides southeastern Massachusetts communities with an alternative to landfilling their municipal solid waste. Since opening in 1989, the facility has employed a shred-and-burn process developed by Energy Answers Corporation (EAC), the SEMASS facility?s developer, enabling the plant?s processing of approximately one million tons of solid waste each year. The resulting electricity meets the needs of more than 75,000 homes. The facility also recovers nearly 20,000 tons of recyclable metals from bottom ash annually.

American Ref-Fuel Company acquired controlling interest in SEMASS Partnership, the facility?s owner, in 1996. Energy Answers Corporation and ESI Energy, Inc. previously composed the SEMASS Partnership.

Among the numerous operational and environmental prizes awarded to the SEMASS facility is the American Academy of Environmental Engineers? Honor Award for EAC?s ash technology. The SEMASS Resource Recovery Facility received its OSHA Star facility designation in 2000 and was recertified as a VPP Star in 2003.
