The Democratic National Convention in Denver will be fueled with ethanol made from beer waste, thanks to a donation from Molson Coors Brewing Company.

The Denver 2008 Convention Host Committee has announced that the leading global brewer and its U.S. subsidiary, Coors Brewing Company, will be the “Official E85 Ethanol Producer for the 2008 Democratic National Convention.”

Molson Coors is donating all the ethanol fuel for the fleet of General Motors flex-fuel vehicles to be used for Convention transportation needs. Coors’ ethanol is made from waste beer generated at their brewery in Golden, Colo.

Coors is the nation’s first major brewer to convert its waste beer into ethanol. The company began recycling waste beer and converting it to ethanol in 1996 and today the Golden ethanol facility produces about three million gallons of ethanol per year.
