DuPont Danisco, United States

Dupont Danisco Cellulosic Ethanol LLC (called DDCE for short) is a 50/50 venture between chemical company DuPont and food processing company Danisco. The company focuses on the production of ethanol from non-food biomass and plans to license its technology to other companies. In 2011, DuPont purchased Danisco, bringing DDCE under the DuPont brand and renaming it DuPont Biofuel Solutions.


The company focuses on three areas of biofuel generation: feedstock, processing, and production. Feedstock technology focuses on the production of crops like sugarcane, corn, and switchgrass. The company genetically modifies these organisms to make them ore drought, weed, and insect resistant. GMO seeds from DuPont are manufacture under the Pioneer Seeds brand name.

Processing technology focuses on the development of enzymes for the conversion of starch to ethanol and biomass to ethanol to increase efficiency and yield. The product, called DuPont FermaSure is also designed to limit growth of bacteria that are harmful in the fermentation process, which can reduce the need for antibiotics.

Finally, production technology is under development to make second generation feedstock conversion more cost effective. The company is building a large-scale biofuel production plant in Iowa to produce “Butmax Advanced Biofuels.” The name reflects the focus on biobutanol production, which can be used in conventional vehicle engines without need for modification of engine components.
