From RenewableEnergyAccess.com: Development Yields Antifreeze from Biodiesel.
In addition to topping off your gas tank with biodiesel, a new advance could let you fill your vehicle's cooling system with a biomass-derived antifreeze.
A new process developed at the University of Missouri-Columbia (MU) creates a valuable secondary product from the biodiesel manufacturing process that makes the production cycle both profitable and affordable.
Galen Suppes, chief science officer of the MU-based Renewable Alternatives, developed a process for converting glycerin, a byproduct of the biodiesel production process, into propylene glycol, which can be used as nontoxic antifreeze for automobiles. Suppes said the new propylene glycol product will meet every performance standard, is made from domestic soybeans and is nontoxic. [continue]
