DuPont, Genencor International and Tate & Lyle Honored for Groundbreaking Work in Developing Bio-PDO(TM)

Date:8/28/2007

in chemistry and engineering with innovative biological processes. The result is a facility in Tennessee that is unique in many ways and is the product of a team with truly diverse backgrounds. This new process puts us on the front lines of the sustainability revolution that will forever change the way we design our products and facilities."

DuPont discovered a unique polymer in the 1940s that was known for its inherent stain resistance, UV resistance and other valued performance attributes. The polymer, now known as DuPont(TM) Sorona(R) renewably sourced polymer, required 1,3 propanediol, a costly chemical that continued to prohibit the polymer's introduction to the market. The Bio-PDO(TM) development program began with a partnership with Genencor to make propanediol from corn sugar. The success of the program resulted in a second partnership, this time with Tate & Lyle in 2000 to commercialize the new biological process to create Bio-PDO(TM). The first commercial shipment of Bio-PDO(TM) occurred in November 2006.

As interest in renewable products has grown, the market for Bio-PDO(TM) has grown. Today, Bio-PDO(TM) is not only the key ingredient in Sorona(R), it also is a versatile, biodegradable and high-performance ingredient that can be used in cosmetics, liquid detergents and industrial applications such as anti- freeze, as well as many other applications that currently use glycols. Demand for new uses of Bio-PDO(TM) continues to grow with nearly a dozen product applications to date.

The production of Bio-PDO(TM) at the world's only commercial facility in Loudon, Tenn., consumes 40 percent less energy and reduces greenhouse gas emissions by 56 percent compared to petroleum-based propanediol. Annual production of 100 million pounds of Bio-PDO(TM) will save the energy equivalent of over 13.5 million gallons of gasoline per year, or enough to fuel more than 27,000 cars.
