Press Release from Poet
SIOUX FALLS, S.D. (September 27, 2007)
Dr. Mark Stowers, the Vice President of Research & Development for POET, will give a presentation on POET's cellulosic project during an eductional event on cellulosic ethanol in Washington, D.C. The event will take place Tuesday, October 2 from 12:00-3:00 p.m. at the National Guard Building on the corner of Massachusetts Avenue and North Capitol. The event is organized by the Renewable Fuels Association and includes presenters from Abengoa Bioenergy, ADM and Verenium.

The cellulosic project that POET is jointly funding with the United States Department of Energy will convert an existing 50 million gallon per year (mgpy) dry-mill ethanol plant in Emmetsburg, Iowa into a commercial cellulosic biorefinery. Once complete, the facility will produce 125 million gallons of ethanol per year, 25 percent of which will be from cellulosic feedstock. By adding cellulosic production to an existing grain ethanol plant, POET will be able to produce 11 percent more ethanol from a bushel of corn, 27 percent more from an acre of corn, while almost completely eliminating fossil fuel consumption and decreasing water usage by 24 percent.
