Swine Waste-to-Energy System Operating at Capacity

Manure collected daily from nearly 30,000 hogs, formerly treated in open air lagoons, mixed with off-site agricultural wastes that were previously either land applied or destined for a landfill, is biologically decomposed in an oxygen-free, 1.2 million gallon reinforced concrete vessel. The bacteria in the digester metabolically break down the organic waste streams and generate energy-rich biogas, while destroying nearly all of the pathogens and odor. The biogas is combusted in an engine/generator, sending enough clean renewable electricity to the local utility to offset the electricity consumption of nearly 300 average size homes in the area.
