What is Biodiesel?
Biodiesel is the name of a clean burning alternative fuel, produced
from domestic, renewable resources. 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 modifications. Biodiesel is simple to use,
biodegradable, nontoxic, and essentially free of sulfur and aromatics.
How is Biodiesel made?
Biodiesel is made through a chemical process called transesterification
whereby the glycerin is separated from the fat or vegetable oil. The
process leaves behind two products -- methyl esters (the chemical
name for Biodiesel) and glycerin (a valuable byproduct usually sold
to be used in soaps and other products).
Biodiesel is defined as mono-alkyl esters of long
chain fatty acids derived from vegetable oils or animal fats which
conform to ASTM D6751 specifications for use in diesel engines. Biodiesel
refers to the pure fuel before blending with diesel fuel. Biodiesel
blends are denoted as, "BXX" with "XX" representing
the percentage of Biodiesel contained in the blend (ie: B20 is 20%
Biodiesel, 80% petroleum diesel).

Why should I use Biodiesel?
Biodiesel is better for the environment because it is made from renewable
resources and has lower emissions compared to petroleum diesel. It
is less toxic than table salt and biodegrades as fast as sugar. Since
it is made in the USA from renewable resources such as soybeans, its
use decreases our dependence on foreign oil and contributes to our
