Biodiesel
|
Biodiesel is a renewable, biodegradable fuel derived from agricultural plant oils or animal fats. It can be used alone or blended with petroleum diesel fuel in diesel engines. Biodiesel blends must be at least 2% biodiesel and are identified by the percentage of biodiesel in the blend. B2, B5, B10 and B99 are the principal biodiesel blends used in the U.S. today.
