Biodiesel is a clean burning liquid fuel produced from domestic, renewable resources like soybeans, peanuts and even recycled cooking oils or animal fats. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modification. Biodiesel is simple to use, biodegradable, non-toxic, and essentially free of sulfur and aromatics. Biodiesel reduces serious air pollutants such as particulates, carbon monoxide, hydrocarbons, and other air toxins. Biodiesel can be made simply and has been for over a hundred years. Biodiesel can be used as a cleaner-burning vehicle fuel and a source for residential or commercial heating.

Technical Definition for Biodiesel (ASTM D 6751) and Biodiesel Blend:

Biodiesel, n—a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM D 6751.

Biodiesel Blend, n—a blend of biodiesel fuel meeting ASTM D 6751 with petroleum-based diesel fuel, designated BXX, where XX represents the volume percentage of biodiesel fuel in the blend.

B20 - 20% biodiesel mixed with 80% petroleum diesel.
B100 - 100% biodiesel
BD - Short for biodiesel
