While all cellulosic biomass contains fermentable sugars, some are more easily accessible for biochemical conversion than others. Feedstock choice is influenced by a number of factors, although gallons-per-acre yield and sustainability are the ultimate considerations.
We are working with crop producers in the US to establish a high-quality, cost-effective, and sustainable supply of corn stover. Our Feedstock Collection Program will set the standard for localized, sustainable biomass collection, transport and storage. It’s a key building block for biorefinery development, including our 30 million gallon (113 litres) per year commercial facility currently under construction in Nevada, Iowa.
Agricultural biomass is a general term applied to plant matter that contains significant amounts of lignin (as distinct from grain, fruits, vegetables, etc.). In addition to agricultural residues like corn stover, sugarcane bagasse, sugarcane straw, and energy crops like switchgrass, DuPont is interested in a range of biomass feedstocks to suit local conditions around the world.
We’re working with local growers throughout the Nevada, Iowa area to secure reliable non-food feedstock supplies.
