Digested Power

Project receives recovery funds
By | December 27, 2010
United Ethanol LLC has started work on installing an anaerobic digester at its 50 MMgy ethanol plant in Milton, Wis. A portion of the plant's thin stillage will be used to create methane, and reduce natural gas use by up to 25 percent. The $6.75 million project is being supported with $2.25 million in state energy program funds, funded through the American Recovery and Reinvestment Act. The anaerobic digester is expected to reduce the number of fermentation solids that have to be recycled, reduce fermentation inhibitors, reduce evaporator bottlenecks and eliminate syrup load-out. Technology provider Eisenmann Corp. will install the digester. The project should take about a year to complete.
