Propylene Glycol from waste Glycerine

Huntsman Corp. (Houston,Texas) plans to commercialize a process for making propylene
glycol (PG) from glycerin, a byproduct of biodiesel production, and will make the product available for customer trials within the next month.

Using proprietary technology, the company will initially make the bio-based PG at its process-development center in Conroe, Texas. The bio-based PG is expected to be commercially available by 2008. Meanwhile, Ashland, Inc. and Cargill are forming a joint venture to develop and produce bio-based chemicals.

Initial plans include a 65,000- m.t./yr PG plant, located in Europe, that will also market refined glycerol.
