Energy-from-Waste Facility

Covanta Marion, Inc.
Brooks, Oregon

The Marion County Energy-from-Waste facility began commercial operation in March 1987, serving the solid waste management needs of the 300,000 people of Marion County, Oregon. The facility operates as Covanta Marion and processes 550 tons per day of municipal solid waste (MSW), which generates up to 13.1 megawatts of renewable energy sold to Portland General Electric. The facility was the first mass-burn waterwall resource recovery facility combusting MSW in the United States to use dry flue gas scrubbers and fabric filter baghouses to control acid gases and particulates. In addition to MSW, the facility processes about 250 tons-per-month of supplemental waste. It is located in Brooks, a small farming community about four miles north of Salem, the state capital, and 40 miles south of Portland.

Notably, the facility has been a member of Oregon's safety and health recognition program, the Safety and Health Achievement Recognition Program (SHARP) Alliance , since 2006 and an Occupational Health and Safety Association (OSHA) Voluntary Protection Program (VPP) Star member since 2008.
