Iowa to Feed One of the World’s Largest Cellulosic Biorefineries

Biomass Plant

Demonstration Plant: Unit at Vonore, Tenn., can produce 250,000 gallons/year of ethanol from agricultural residues.

After almost a decade of research, development and trials, advanced biofuels are moving toward commercialization. Five established companies intend to build large-scale biorefineries in the U.S. over the next 12 to 18 months. When operational, these facilities will generate nearly 110 million gallons of advanced biofuels annually.

DuPont is in the process of constructing one of these biorefineries — a facility in Nevada, Iowa, that the company broke ground on in November 2012. The plant will be one of the first and largest commercial biorefineries in the world making fuel from cellulose. The facility will take 18 months to complete and will produce 30 million gallons a year of cellulosic ethanol via conversion of corn stover from local farms. Specifically, to supply the corn stover for the plant, DuPont will contract with more than 500 local farmers to gather, store and deliver more than 375,000 dry tons of stover per year to the Nevada facility. The stover will be collected from an approximate 30-mile radius around the new facility and harvested off of 190,000 acres.
