The company has a deal with the nearby Central Disposal landfill – located in Winnebago County in far northern Iowa – which converts its methane gas byproduct into usable energy. This energy heats the greenhouse during the winter which allows Perfect Circle to grow its signature organic tomatoes year-round.
Other parts of Iowa have embraced similar practices such as the Landfill Gas Project – a collaboration of the University of Iowa, the City of Iowa City, and Mid-American Energy – that aims to “transport landfill gas from the City of Iowa City landfill to the University of Iowa/Oakdale Research Park via an underground pipeline.” Maryland-based Fiberight has also announced plans for trash-to-energy centers in Blairstown and Marion. As far back as 1999 researchers at Iowa State University have experimented with extracting methane from manure which produces energy while also controlling odor.
