In a world where Green Technology is creating awareness among people, bio-diesel can be considered a modern invent to cope with a problem arisen with urbanization and gas-powered vehicles, however this fuel was first tested by Dr. Rudolf Diesel experimenting with peanut oil to run a diesel engine, but it was until August 31, 1937 when Belgian researcher G. Chavanne of the University of Brussels was granted with the patent number 422,877 accrediting to him invention rights on bio-diesel described in the document as \\\\\\\"a procedure for the transformation of vegetable oils for their uses as fuels.\\\\\\\"

Perhaps this description has triggered a common misconception around bio-diesel that makes people believe this fuel can only be obtained from raw vegetable oil without further processing. Nonetheless, to obtain bio-diesel it is necessary take vegetable oil, or any other biodegradable fat, through a chemical process to aisle glycerin. This procedure is called transesterification and produces two reusable bio-products; pure glycerin that is used in cosmetic and health care industry and bio-diesel, which chemical name is methyl esters.

Actually there are numerous bio-diesel fueling stations across Europe and their number is increasing every day in other countries, but especially yin the United States and Canada. Because this fuel can be used in its pure form or combined with petroleum diesel, the engines of many transport fleets are \\\\\\\"bio-diesel ready,\\\\\\\" condition that boosts improved performance on the road.

Making your own homemade bio-diesel is not that hard. As noted, it can be obtained from vegetable oil, animal or biodegradable fat after separating glycerin from methyl esters in a purification process derived from a chemical reaction. To make your own bio-diesel at home you simply need 75% vegetable oil, 22% methanol, and 3% lye or another catalyst such as soda caustic or soap.

As a note of precaution protect your skin and eyes while preparing the fuel. Pour oil into a crystal bottle and combine it with methanol and the catalist. Stir slow and carefully, then allow a settling period after which bio-diesel is ready but needing further filtration and drying. This process consists of removing waste oil and water content from your fuel. Set aside for a second settling period, and again removing this time the glycerin layer resulted from the chemical reaction.

Finally, wash your bio-diesel fuel thoroughly by removing waste oil again and let it dry for a second time. The result is a variant of bio-fuel that is know as either Straight Vegetable Oil (SVO) fuel or Pure Plant Oil (PPO) fuel that you can try in your engine with confidence.
