In South Dakota, POET-DSM Advanced Biofuels has contracted with International Technology Group ANDRITZ, through its U.S. subsidiary ANDRITZ Inc., to supply a two-step biomass treatment process for the commercial-scale cellulosic bio-ethanol plant under construction in Emmetsburg, Iowa. The ANDRITZ technology is a two-stage process that includes a vertical reactor, an interstage washer and then the continuous steam explosion technology (Advanced SteamEx process) to draw out available sugars from the cellulose material. Project LIBERTY is expected to produce 20 million gallons per year of cellulosic bio-ethanol, growing to about 25 million gallons per year. The facility will use corn cobs, leaves, husk and some stalk to produce its renewable biofuel. Construction is scheduled to be complete in late 2013, and this fall farmers are increasing the amount of biomass delivered to the site in an effort to fine-tune storage efforts and get farmers used to the biomass collection process. POET-DSM officials confirmed that the plant will hit its goal of collecting about 85,000 tons of corn cobs and light stover in this harvest season.
