Two Cellulosic Ethanol Plants at Commercial Scale Opened in Iowa in September 2014

In early September 2014, the United States’ first two commercial-scale cellulosic ethanol plants opened in Iowa.  Cellulosic ethanol is produced from cellulose in plant residues—such as corn stalks, leaves, and cobs—rather than from grain (the corn kernel), which is the source for the corn-based ethanol that for many years has been commercially produced and blended with gasoline.  The two plants, both in northwestern Iowa, are the Project Liberty plant near the town of Emmetsburg, operated by the DSM and Poet companies; and the Quad County Corn Processors plant near the town of Galva.
