VALPARAISO, Ind. (AP) -- Valparaiso is looking at using food waste to increase the amount of methane now generated at the northwestern Indiana city's sewage treatment plant.
The Times of Munster reported Sunday that the Valparaiso Utilities Board voted last week to approve a contract with MWH Americas Inc. of Chicago for a feasibility study.
Assistant Utility Director Steve Poulos told the board the additional methane could be used to power a turbine that would generate electricity and offset the plant's $340,000 annual electric bill. He says methane created from the processing of sewage already is used to heat all the buildings on the treatment plant campus and the tanks used to break down sludge. It has helped the city save about $500,000 over the past decade.
