DuPont Sorona® Earns Awards For Sustainability

DuPont Sorona® - Wilmington, Del.-based DuPont's first polymer derived from a biological source - recently received two awards in recognition of its environmentally sustainable benefits.

In China, Sorona beat out more than 1,000 other products to win the Most Visionary Innovation in the sports and health category, presented by the China State Intellectual Property Office and China Central Television.

The Society of Plastics Engineers, Brookfield, Conn., presented Sorona with its 2005 New Technologies in Renewable Materials and Processes award at the Global Plastics and Environmental Conference, held last month in Atlanta.

DuPont scientists have developed a new process to derive 1,3 propanediol, DuPont Sorona® 's key ingredient, from corn. The key ingredient in Sorona, 1,3 propanediol (PDO), was derived originally from petrochemical sources. DuPont scientists recently developed a new process to derive PDO from corn. The new process consumes more than 40 percent less energy than conventional petrochemical feedstock. Bio-PDO will be available commercially in 2006.
