Lansing-area state vehicle drivers can obtain B20 at VTS at the State Secondary Complex.  A list of public biodiesel fueling stations in Michigan is available on the National Biodiesel Board website.

According to the US Department of Energy's Alternative Fuels Data Center:

"Biodiesel fuel can be made from new or used vegetable oils and animal fats, which are nontoxic, biodegradable, renewable resources. Fats and oils are chemically reacted with an alcohol (methanol is the usual choice) to produce chemical compounds known as fatty acid methyl esters. Biodiesel is the name given to these esters when they're intended for use as fuel. Glycerol (used in pharmaceuticals and cosmetics, among other markets) is produced as a byproduct."

Production of biodiesel is increasing rapidly.  The grand opening of Michigan's first biodiesel plant was held on July 13, 2006 in Bangor, a small community west of Kalamazoo.  The new plant is part of a 12 acre Agricultural Processing Renaissance Zone established in cooperation with the Michigan Economic Development Corporation and Michigan Biodiesel LLC, a partnership of 50-plus independent investors who raised funds to build the plant for production of fuel from soybean oil.  Another plant is currently under construction in Gladstone in the Upper Peninsula.
