New Waste-to-Energy Projects Planned Throughout the United States
The ongoing installation of a fuel cell power plant at a Los Angeles wastewater treatment facility is just one of many projects underway in the United States to convert waste into energy. In Vermont, for instance, a wastewater treatment facility in Essex Junction is planning to make better use of its digester gas by installing microturbines, which will produce enough electricity to meet 41 percent of the facility's power needs. The microturbines will also generate enough heat to warm the facility's digester tanks. Currently, the facility burns more than half of its digester gas in a boiler to heat the digester tanks, and flares off the remainder of the gas. Northern Power Systems will engineer, build, and install the new microturbines and associated control systems. See the Northern Power Systems press release (PDF 72 KB). Download Acrobat Reader.
In the Midwest, Environmental Power Corporation is forming a strategic alliance with Dairyland Power Cooperative in an effort to convert animal waste from poultry and swine farms into electricity. Environmental Power uses an anaerobic digestion process to convert manure into biogas, which is then burned to generate electricity. The company plans to deploy systems totaling 25 megawatts in capacity throughout Dairyland's service area. Dairyland Power Cooperative sells wholesale power to electric power cooperatives and municipal utilities in 62 counties in the states of Wisconsin, Minnesota, Iowa, Illinois, and Michigan. See the Environmental Power press release.
In 2002, Environmental Power signed similar agreements for power facilities in Wisconsin, New York, and New England. The company expects the Wisconsin installations to be operating by August. See the Environmental Power press releases from July 11 and October 15, 2002.
