On September 3, 2014, POET-DSM's Project LIBERTY in Emmetsburg, Iowa, celebrated its grand opening. This will be the first commercial-scale cellulosic ethanol plant to use corn waste as a feedstock, using biochemical conversion technologies (yeast and enzymes) to convert cellulosic biomass into transportation fuels. Project LIBERTY is the second of two DOE-funded cellulosic ethanol biorefineries to come on line within the past year. More information is available on the DOE Bioenergy Technologies Office (BETO) website. A documentary on the production of cellulosic ethanol at POET-DSM can be viewed online.
