The City of Columbia Missouri Landfill has won approval from the state Department of Natural Resources to operate the state's first bioreactor, one of only ten in the country. Bioreactors inject water into the landfill and recirculate leachate to enhance waste decomposition. Research from other projects indicates that bioreactors increase available landfill space and accelerate the production of landfill gas which enhances its use in energy recovery. Columbia's project began in 2005 and is separate from its 2.1 megawatt landfill gas-to-energy operation which came online in June 2008. The bioreactor is expected to double its output.
