"NEVADA, Iowa -- Science and engineering company DuPont has started construction of a large cellulosic ethanol biorefinery in Iowa, with completion expected in mid-2014."
"Once fully operational, the facility will produce 30 million gallons of cellulosic ethanol a year from corn stover residues, a feedstock composed of corn stalks and leaves. The stover will be collected from farms in a 30 mile radius around the new facility.
This US$200 million facility will be among the first and largest commercial-scale cellulosic biorefineries in the world. The company says this first commercial facility will require a capital investment of about $7 per gallon of annual capacity."
