Glycerin CHP

Or here's another idea on what to do with the excess glycerin...just burn it! This seems a much better option frankly.

One-tenth of every gallon of biodiesel that is produced is crude glycerin. The biodiesel byproduct is a colorless, odorless, viscous liquid that has traditionally been used in the manufacturing of a wide variety of products in the food, cosmetic and pharmaceutical industries. The supply of crude glycerin entering the U.S. marketplace remained relatively stable until 2003, when biodiesel production began to increase. Since then, the supply of crude glycerin has nearly doubled, while demand for the product has remained largely unchanged. This excess supply and limited demand has caused glycerin prices to remain depressed.

Possible experimental applications for glycerin at the moment:

Zhiyou Wen, an assistant professor of biological systems engineering with Virginia Tech’s College of Agriculture and Life Sciences, is developing a technology that will use glycerin to aid in the production of algae that produce omega-3 fatty acids.

A newly developed technology in the U.K. allows glycerin to be burned in off-the-shelf diesel generators that are used in combined-heat-and-power applications.

Transform glycerin into alcohol using e coli.
