DES MOINES, IA., November 27, 2006 -- Commercial production of Bio-PDO™ from corn sugar is a significant milestone for agriculture and for Pioneer Hi-Bred International, according to company officials. Pioneer is a subsidiary of DuPont which today announced DuPont Tate & Lyle Bio Products, LLC, an equally-owned joint venture of DuPont and Tate & Lyle, the first commercial shipments of Bio-PDO™, from its $100 million facility here in Eastern Tennessee.

According to Pioneer President Dean Oestreich (oos-trick), Bio-PDO™ is a totally new corn-based product that can be used to make a variety of consumer products replacing petroleum-based propanediol.

“Bio-PDO™ is a new product made from corn in a fermentation process and that product is used to make new consumer goods and in many cases we are replacing the use of petroleum products,” said Oestrich. “So, this is pretty exciting news to both farmers who are growing corn and consumers who are taking advantage of these new products made from the renewable resources of agriculture.”

Oestreich says Bio-PDO™ is a raw ingredient for a variety of goods.

“We’re using it in a new DuPont fiber called Sorona®, which is made into a carpet with great stain protection, mildew-resistance, durability. It’s also used in apparel. It has great softness, comfort and stretch-recovery.”

Oestreich says Bio-PDO™ is a perfect example of the commitment on the part of DuPont and Pioneer to develop new industrial markets for agricultural producers and more renewable products for consumers.

“Pioneer has really been focused on improving grower and farmer productivity for 80 years and we are an industry leader in connecting growers to downstream markets,” said Oestreich. “And for the DuPont side we are connecting that into the consumer world.”

Bio-PDO™ is also well suited for cosmetics, liquid detergents and industrial applications like anti-freeze. The production of Bio-PDO™ consumes 40 percent less energy and reduces greenhouse gas emissions by 20 percent verses petroleum-based propanediol. Production of 100 million pounds of Bio-PDO™ will save the equivalent of 10 million gallons of gasoline per year, or enough to fuel 22,000 cars annually.
