Wilmington, Del.-based DuPont and London-based Tate & Lyle Plc, looking to build upon a
proprietary fermentation and purification process they developed for 1,3 propanediol (PDO), have
established a joint venture company, DuPont Tate & Lyle BioProducts LLC. The new company, to be
based in Wilmington, will begin commercial production of PDO – the key building block in DuPont
Sorona® polymer – in 2006 at a new facility in Loudon, Tenn. A pilot facility has been in operation
in Decatur, Ill., for several years. Sorona is suitable for a variety of applications including
apparel, interiors, engineering resins and packaging.
