American Process Waste-to-Cellulosic Ethanol Project Launches in Michigan

Green Car Congress

American Process Incorporated (API) recently launched a waste-to-cellulosic ethanol biorefinery project in Alpena, Michigan. The biorefinery will convert the process waste effluent from the plant into cellulosic ethanol, sodium acetate and clean, warm water. Dewatered solids are then returned to the biomass boiler.
