Plans for DuPont’s First Commercial Cellulosic Ethanol Plant 27.5 million gallon/year plant planned to be built in Nevada, Iowa (on 57.75 acres of land recently purchased by DuPont) with startup by 4Q13/1Q14. Utilizes stover to fuel-grade ethanol technology developed in Rendering of biorefinery Wilmington, DE and demonstrated in Vonore, TN. Strategically positioned close to Pioneer HQ/R&D center (Johnston) as well as Genencor enzyme production plant (Cedar Rapids) 6
