NEW YORK, May 2, 2007 – Speaking at an investors’ conference here today, DuPont Biofuels Vice President & General Manager John Ranieri said the company’s strategy to bring biobutanol and cellulosic ethanol technologies to market will help address the global need for alternative and more sustainable transportation fuels.

"Oil remains the prime energy source for transportation fuels with increasing demand, particularly from China and India, placing additional pressure on current oil supplies. The need to diversify the fuel supply with more sustainable solutions is a large opportunity for agricultural-based alternatives," Ranieri said.

The Integrated Corn Based Biorefinery (ICBR) is a systems-based approach that is being developed to convert cellulosic feedstocks into biofuels and other renewable products.

"An integrated approach to convert cellulosic biomass to biofuels is necessary to achieve the economics needed to be competitive," Ranieri said. "Capital investment and operating costs must be comparable with incumbent grain ethanol technologies. We are focused on feedstock collection systems, cost-effective pre-treatment and optimized fermentation technology that assures high yields and lower costs for biofuels derived from cellulosic feedstocks."

Biobutanol is the first advanced biofuel being developed by DuPont in partnership with BP. Biobutanol addresses market demand for fuels that can be produced from domestic renewable resources in high volume and at reasonable cost; fuels that can be used in existing vehicles and existing infrastructure; fuels that offer good value to consumers; and fuels that meet the evolving demands of vehicles.

"Recent fuels testing has shown that biobutanol is an advanced biofuel because it is similar to gasoline, and performs exceptionally well in vehicles," Ranieri said.

DuPont has a three-part biofuels strategy: (1) improving existing ethanol production through differentiated agricultural seed products and crop protection chemicals; (2) developing and supplying new technologies to allow conversion of cellulose to biofuels; and (3) developing and supplying next generation biofuels with improved performance.

DuPont – one of the first companies to publicly establish environmental goals 16 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment like biofuels. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets, including products based on non-depletable resources, like biofuels.

DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries and regions, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.
