Great Lakes Region Food Industry Biogas Casebook

Posted on March 1, 2011, in Research

Food and beverage producers have been using anaerobic treatment of their production wastewaters for decades. These systems have become increasingly popular in recent years for both economic and environmental reasons. As energy costs have risen, the reduced energy intensity of anaerobic digester treatments over aerobic treatment options has presented a clear cost advantage for facilities […]

AURI and Minnesota corn and soybean grower groups are helping evaluate the idea’s technical and […]

A digestible idea

Posted on April 1, 2008, in Ag Innovation News

Anaerobic digestion could boost ethanol plant profits by millions of dollars — and make corn ethanol “greener.” That’s the finding of a new AURI-sponsored study that showed the feasibility of making methane and fertilizer from thin stillage, dissolved corn solids left over from ethanol production. “Ethanol plants could potentially become energy independent if all the […]
