Covanta Huntsville, Inc.
Huntsville, Alabama

The Huntsville Solid Waste to Energy Facility, operating as Covanta Huntsville, Inc., is located on 20.5 acres adjacent to Redstone Arsenal in Huntsville, AL. Covanta Huntsville began commercial operation in July 1990. The facility processes 690 tons per day of solid waste and sewage sludge from the Huntsville wastewater treatment plant. Covanta Huntsville produces nearly 180,000 pounds of steam per hour, which travels through a six-mile long export line for the arsenal's heating and air conditioning needs. The facility is equipped with four fossil-fuel package boilers which allow steam to be available 100 percent of the time. The facility is also equipped to burn biogas from a nearby landfill.
