CHATTANOOGA, TN – In the next few months all of Chattanooga city’s 300-plus diesel vehicles will run on a B-20 blend, according to the Web site www.wdef.com. Biodiesel is a renewable fuel made from vegetable oil or animal fat. Most of the biodiesel in the U.S. comes from soybean oil.
Fleet Manager Brian Kiesche twisted a few arms to get the program going, but the idea finally caught on, the report said. Aside from saving money, the city of Chattanooga wants to improve air quality.
