Tools And Expert Help At Every Turn

Homestead Green Energy Biomass Facility

Based in Plymouth, Indiana, Homestead Dairy has 1,800 milking cows and 1,700 cows come in from three nearby facilities for milking. Continued success increased cow manure and the odor was directly impacting the nearby residents. They decided to build a biomass waste-to-energy facility to convert the manure into electric power and Homestead Dairy partnered with local Cat dealer, Michigan Cat, to customize a green energy power generation system.
