DuPont Co. has joined a state initiative to build the first pilot-scale biorefinery in the U.S. that would take corncobs and switchgrass grown on Tennessee farms and convert the biomass into ethanol for fuel.
The announcement Wednesday by Gov. Phil Bredesen and DuPont officials marks a change in development partners for the University of Tennessee-managed cellulosic ethanol project.
The project has received a $40.7 million commitment from the state and a $26 million grant from the U.S. Department of Energy.
Mascoma Corp. of Boston was Tennessee's original technology and financing partner. Now Delaware-based DuPont will fill that role as part of a joint venture with Genencor, a division of Denmark-based Danisco AS.
