In this video from Earth Island Institute's New Leaders Initiative, meet Andrew Azman, a college student at the University of Colorado. When Azman suggested running the university's buses on biodiesel, people were skeptical. But he persevered. He built a processor to convert used french fry grease into biodiesel, and convinced the university to run a campus bus off the fuel. Eventually, this led to all 13 campus buses converting to biodiesel, a commitment from the city of Boulder to use biodiesel in its fleet, and the opening of the first public biodiesel pump in Colorado.
