The Huntsville Solid Waste to Energy Facility, located on 20.5 acres adjacent to Redstone Arsenal, 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. This facility has no electric generating capabilities, but it does produce nearly 180,000 pounds of steam per hour that travels through a six-mile long export line for the Arsenal's heating and air conditioning needs. Because the facility is equipped with four fossil-fuel package boilers, it provides complete redundancy and, as such, steam is available 100 percent of the time. The facility is also equipped to burn landfill gas from a nearby landfill.
