The Hillsborough County Resource Recovery Facility, operating as Covanta Hillsborough, Inc., began commercial operation in October 1987. After a 2009 expansion that increased its processing capacity, the facility now processes up to 1,800 tons per day of solid waste. The facility, located near Tampa, FL, generates up to 46.5 megawatts of renewable energy and is owned by Hillsborough County, which supplies the waste processed at the facility. Covanta Hillsborough recycles secondary sewer treatment runoff from the adjacent wastewater treatment plant as part of its process water. It also maintains emissions control equipment in compliance with the United States Environmental Protection Agency's Clean Air Act.
