DuPont and Tate & Lyle form biopact

May 31, 2004 | APPEARED IN VOLUME 82, ISSUE 22

DuPont and corn and sugar refiner Tate & Lyle have formed a joint venture to create products from renewable resources. The equally owned venture, DuPont Tate & Lyle BioProducts, plans to build a plant by 2006 at Tate & Lyle's Loudon, Tenn., site. It will make up to 100 million lb per year of 1,3-propanediol (PDO) via a proprietary fermentation process the two have been developing since 2000. A pilot plant has been operating for several years at Tate & Lyle's Decatur, Ill., site. PDO is a key building block for polypropylene terephthalate, a polymer that DuPont sells as Sorona. The partners claim the new biobased PDO technology consumes less energy than the petrochemical route now in use while also employing renewable resources.
