Biodiesel

Biodiesel as a biofuel
Biodiesel is a truly amazing substance that is probably the future of diesel. This biofuel is obtained when the glycerin is removed from fat or Vegetable Oil. The glycerin can then be put into soap and the rest, methyl ester, is biodiesel. Biodiesel is flammable.

How can we use biodiesel as a biofuel?
Biodiesel can replace diesel in a diesel engine or be mixed with petroleum diesel to form a biodiesel blend.

How it's used today
Biodiesel is currently fixing the USA's problem of depending on foreign oil by making biodiesel from native products. It can be purchased directly from the producers and marketers of biodiesel and are available at several public pumps throughout the country. Biodiesel produces less emissions than normal diesel and can biodegrade in case of leaks.

Disadvantages
Though biodiesel pollutes less than diesel, it pollutes nonetheless.
