DuPont's First Biologically Derived Polymer Receives Global Recognition

11 February 2005

DuPont's newest polymer innovation, the first DuPont polymer derived from a biological source, has been recognized by the China State Intellectual Property Office and China Central Television (CCTV) as ""Most Visionary Innovation"" at a recent award ceremony.

Also, on Feb. 25, DuPont Sorona will receive the 2005 ""New Technologies in Renewable Materials and Processes"" award at the Global Plastics and Environmental Conference, sponsored by the Society of Plastics Engineers (SPE).

Conference Chairman Tim Kettering said, ""The story of Sorona is unique because it demonstrates that the use of renewable materials and processes can create new performance technologies and products.""

At the January 2005 Innovative Design Night, sponsored by the China State Intellectual Property Office and state-run CCTV, Sorona was selected as the ""Most Visionary Innovation"" in the sports and health category. Fabrics made with Sorona for active wear, apparel and sportswear are commercially available through Chinese fibre and fabric manufacturers. More than 1,000 products from multinational and local companies were considered for this recognition.

The judging panel commented, ""Chemical fibres can now be made with natural ingredients. This will reduce the dependency of traditional chemical fibre products on oil resources. It will be another bold attempt in the innovative use of renewable resources. Crops and plants are becoming the most reliable backup power for the resource consumption of humans and will serve to further protect the environment.""

DuPont scientists recently developed a way to make Bio-PDO, the key Sorona ingredient, from corn using a new biological process that requires over 40 percent less total energy than the traditional petrochemical feedstock. It will be commercially available in 2006. In 2003, the U.S. Environmental Protection Agency presented DuPont with its annual ""Presidential Green Chemistry Award"" for the company's research leading to the development of Bio-PDO.
