DuPont Bio-Based Polymer Platform Earns Green Chemistry Award

Green Chemistry Award
DuPont rises to the Green Chemistry Challenge


Creating a bio-based process that uses renewable resources instead of petrochemicals to produce a polymer platform for use in clothing, carpets and automobile interiors was an important achievement, supporting our company-wide commitment to sustainable growth. The U.S. Environmental Protection Agency (EPA) recognized this innovation by presenting its Presidential Green Chemistry award to DuPont in 2003. Since then we have brought our science to market, through DuPont™ Sorona® polymer. 

The Presidential Green Chemistry Challenge

Market-Based Science and Sustainable Growth

DuPont, with joint development partner Genencor International, developed a bio-based process using renewable resources – like corn – instead of typical petrochemicals. Through metabolic engineering of biochemical pathways, a microorganism was engineered to use sugars from corn in a fermentation-based process as the basis for production of 1,3 propanediol (PDO), the key building block for DuPont™ Sorona® polymer.

Sorona® polymer is one of the company's newest polymer platform that can be used in applications like textile apparel, carpeting and packaging. This bio-based method uses less energy, reduces emissions, and employs renewable resources compared to traditional petrochemical processes.

“As a science company whose mission is sustainable growth, DuPont is committed to research initiatives that provide shareholder and societal value while reducing our environmental footprint," said DuPont executive vice president and chief innovation officer Dr. Thomas M. Connelly. "The path to bio-based Sorona® polymer combines the emerging discipline of metabolic engineering with the leading polymer capabilities of DuPont."
