Ethanol Production

Thin Stillage could serve as an excelent source for biogas and renewable energy. Ethanol plants in the U.S. produce millions of gallons of Ethanol every day. For every gallon of ethanol up to four gallons of stillage are produced.


Stillage contains solids and an energy rich liquid phase. After separation the solids (DDGS) serve as cattle feed. The liquid fraction - normally send to an evaporator - can serve as an energy rich feed to an anaerobic digester system. Anaerobic digestion can generate up to 30% of the daily energy demand. Besides that it reduces green house gas emissions and generates carbon credits.


For an estimate on the potential kWh/gallon of thin stillage possible please see the biogas calculator.
