Fuel from Cooking Oil, Are you Serious?!

Yes really, more than and beyond the definition of the word ‘serious’. Used cooking oil from your everyday frying of chicken, fries and pork can now be used as fuel for your cars through recycling. These are called Biodiesel and it has started a revolution as an alternative to expensive fossil or mineral oil.

The first known and recorded use of vegetable oil as fuel in an engine was a demonstration of a diesel engine built by the Otto Company and was designed to burn mineral oil, which was then run on pure peanut oil at the 1900 World's Fair. After several years of research, Rudolf Diesel, inventor of the diesel engine, investigated using vegetable oil to fuel the engines he designed.

He presented this idea in 1912 to the British Institute of Mechanical Engineers and successfully cited a number of efforts in this area and he envisioned that though regular cooking oil or vegetable oil sources may seem insignificant back then, the fact that such oils would perhaps have the same importance as natural mineral oils and the tar products in due course of time.

From then on, numerous groups had started an obsession on the research into cooking oil as a diesel substitute. The use of vegetable oil in the mainstream had enjoyed its success during the early 1980s at the height of the spiraling prices and shortages of petroleum and other mineral oil.

How is it made to work with automobiles? Inventors and developers would say it simply as recycling the oil and applying the same concept in refining petroleum oil. They commonly joke as if it’s just like making coffee. The mixture is just simple: a used cooking oil of typically vegetable or coconut sources, a methanol and a catalyst which is composed of potassium and sodium.

The said mixture of three (cooking oil, methanol and catalyst) doesn’t require heating from expensive pumping stations and can be made easily, even at home provided one has the proper knowledge, tools and storage. A generally accepted mixture of 100 liters of cooking oil (costs around $0.50 per liter) plus 20 liters of methanol (usually at $1) plus one kilo of catalyst (costs around $3.5) can create 100 liters of biodiesel as well as an excess of 20 liters of glycerin (which can be used as main ingredient for everyday bath and laundry soap).

What’s more surprising is that it was tested in an unmodified older Mercedes Benz and ran for hundreds of miles during a 2006 University of Idaho invention exhibit.

Today, countries like Russia, Azerbaizan, India, Bulgaria, Paraguay and the Philippines have implemented extensive development of used cooking oil or vegetable oil to power up vehicles as well as other machineries. Major automobile manufacturers like Honda, Toyota, Ford and General Motors have slowly introduced newly designed automobile engines that support the use of Biodiesel fuel especially with the rising prices of petroleum and the collapse of the US and other European economy.
