Official opening of the cellulosic ethanol biorefinery of Dupont in Iowa



DuPont will open its 30-million-gallon cellulosic ethanol biorefinery in Nevada (Iowa, USA) on October 30. The Bioenergy Technologies Office (BETO) Director, senior government officials, DuPont staff and local farmers will attend the grand opening ceremony and plant tour. The biorefinery will be fueled by corn stover biomass harvested from a 30-mile radius around the facility. According to DuPont, the plant has provided many job and financial opportunities for this rural area: 1,000 construction-related jobs, 85 permanent jobs at the plant, 500 local farmers to supply the corn stover and 150 people involved in collection, transportation and storage of seasonal feedstock.

The completion of this biorefinery is a key milestone in the emerging production of cellulosic ethanol. In fact, it is the largest of the four commercial-scale plants (based on enzymatic conversion pathways) currently in operation in the United States: ACE Project (Iowa, 2 Mgal/y), Project Liberty (Iowa, 20 Mgal/y), Hugoton Biorefinery (Kansas, 25 Mgal/y) and Nevada Biorefinery (Iowa, 30 Mgal/y).

Over the last years, DuPont has invested hundreds of millions of dollars to deliver on the potential of cellulosic ethanol. A demonstration facility in Vonore (TN, USA) has generated the data necessary for commercial production. This 250,000-gallon demo plant began operation in 2009 working in partnership with Genera Energy and The University of Tennessee Biofuels Initiative. Also, DoE has supported DuPont by funding key bioenergy conversion technologies and collaborating on research and development projects. In total, DoE has contributed more than $51 million dollars to make this project come true.
