The advent of cellulosic ethanol production online has prompted the co-location of anaerobic digesters at the plants to recover biogas from soluble residues, naturally encountered in the ethanol production process. These soluble residues contain energy sources which can be recovered using the anaerobic digestion process. The biogas thus captured can be used to fill the energy requirements. Recently, DuPont unveiled the world’s largest cellulosic ethanol facility in Iowa. At its full capacity, the bioenergy plant will be able to produce 30 MG of cellulosic ethanol in a year. Prior to this, another ethanol facility was opened in 2014 by Poet-DSM with a capacity of producing 20 MG per year.
