What is Biodiesel?

Biodiesel refers to a diesel-equivalent, processed fuel derived from biological sources such as vegetable oils, which can be used in unmodified diesel-engine vehicles.  In order to use this oil in a diesel-engine, the oil must be modified in a chemical process called transesterification, in which the glycerine is removed from the oil, thus making  it an alkyl ester.  The result of this process is thinner than vegetable oil, and can power a diesel engine as a fuel without making any modifications to the engine.  Biodiesel can be blended with petroleum diesel in different proportions, and this is designated by a number, for instance, "B20" is 20% biodiesel and 80% petroleum diesel, and "B5" is 5% biodiesel, and "B100" of course is pure biodiesel, or what is known as "neat" biodiesel.

Environmental Benefits

• Biodiesel reduces emissions of carbon monoxide by 50%

• Biodiesel contains fewer aromatic hydrocarbons

• Biodiesel can reduce by as much as 20% the direct emissions of paticulates, small paticles of solid combustion products on vehicles

• Biodiesel is biodegradable and non-toxic
