Chocolate Biofuel

I have a friend who drives a biofuel car run on waste restaurant fry oil—and it’s true, she leaves a faint trail of French fry aroma everywhere she drives. Next up: a possibly better smelling option, chocolate. A U.K.-based company Ecotec has developed a method of turning chocolate processing waste products, usually dumped in landfills, into biofuel. (The firm first turns the waste into bio-ethanol, and then mixes it with vegetable oil to produce biodiesel.) This past November, two British men took a journey fueled by chocolate waste from England's southern coast to Timbuktu, Mali in West Africa, aiming to raise awareness of biofuels—a new meaning to a sweet road trip. -Denise Shoukas
