Research yields pricey chemicals from biodiesel waste
Date: 15.7.2008
In a move that promises to change the economics of **biodiesel refining**, chemical engineers at Rice University have unveiled a set of techniques for cleanly converting **problematic biofuels waste** into chemicals that fetch a profit.
The latest research is available online in the journal Metabolic Engineering. The new paper and others published earlier this year describe a new fermentation process that allows E. coli and other enteric bacteria to convert **glycerin** - the major waste byproduct of biodiesel production - **into formate**, **succinate** and other valuable organic acids.
