A French farm co-op is putting animal fat to new use by converting a tractor and two vehicles to run on duck fat biofuel. "We also have frying oil and fat from pigs and calves," said Jules Charmoy, an organic farmer in the cooperative. "There's a little bit of everything in there, but the dominant thing is duck because we're in the Dordogne.
Last year, the French cooperative, which contains over 50 farms, produced over 5,200 gallons of duck fat biodiesel. In the Dordogne area, over two million ducks are raised per year.
