Food for the Road

Fill ’er up with rotten vegetables: A prototype for a Swiss sports car called the Rinspeed R One gets its power from a biogas made of methane fermented from kitchen and garden waste. It can run for about 60 miles (100 kilometers) on 220 pounds (100 kilograms) of waste while producing less carbon dioxide than gasoline.

These biogas cars aren’t on the road yet, but thousands of other food-recycling vehicles are. In the U.S. more than 200 fleets of vehicles are running on biodiesel made from vegetable oil. Any diesel engine can burn it with less soot than regular diesel. Twenty million gallons (76 million liters) of biodiesel fuel are sold annually in the U.S. Nearly 10 percent is made from recycled restaurant grease. “The number of restaurants has grown so much,” says K. Shaine Tyson of the National Renewable Energy Lab, “there’s excess cooking oil available to make more than 400 million gallons (two billion liters) of biodiesel.” An added attraction (or not): Biodiesel-burning cars can smell a bit like french fries.
