How It Works: Second Generation Biofuel Conversion for the Production of Cellulosic Ethanol

Learn how DuPont converts renewable feedstock to second generation cellulosic ethanol.

Since 2008, we have been developing an integrated solution for the commercial scale conversion of biomass into second-generation ethanol. At our demonstration plant in Tennessee, DuPont combines long-standing expertise in biorefinery design with an optimized technology package of novel enzymes and fermentation organisms, with the following outcomes:

  • Demonstrated lower-capital integrated unit operations
  • Achieving economic and environmental targets
  • Produced stover-based ethanol used in many vehicles at the University of Tennessee

Converting Corn Stover to Second-Generation Cellulosic Ethanol at Commercial Scale

This optimized conversion process will be deployed at the DuPont Cellulosic Ethanol facility near Nevada, Iowa. Once fully operational, this corn stover-to-ethanol biorefinery will produce 30 million gallons of cellulosic ethanol annually, and be one of the largest cellulosic biorefineries in the world.
