Bio Diesel fuel is a diesel equivalent, processed fuel derived from biological sources, such as vegetable oils, which can be used in unmodified diesel engine vehicles.

It can also be used as a heating fuel in domestic and commercial boilers. There are a number of naturally occurring and renewable resources it can be refined from including algae, vegetable oils, animal fats or recycled restaurant greases. It can also be processed where ever the raw materials to make it exist.

Bio diesel fuel is nearly completely free of sulfur and aromatics and is a naturally oxygenated fuel because it is composed of almost 10 percent oxygen. Because of this biodiesel provides a significant reduction in particulate and carbon monoxide emissions then petroleum based diesel fuel.

It is also safe to handle and transport because it is has the biodegradability of table sugar, is 10 tens less toxic then plain salt, and has a high flashpoint, the temperature at which it catches fire, of 300 degrees Fahrenheit as compared to regular diesel fuel which flashes ate 125 degrees Fahrenheit. Bio diesel can also be blended with petroleum diesel to create a biodiesel blend as well as its ability to be used in almost any diesel engine without any modifications.

Many gas stations are beginning to make biodiesel available to consumers and a growing number of transport fleets are using it as an additive to their fuel. It is important that fuel grade bio diesel be refined to tight industry specifications in order to ensure proper performance. One of the benefits of this fuel is it lower engine wear. In fact some vehicle manufacturers are beginning to make engines specifically for bio diesel for this reason.

Because it is a better solvent then regular diesel it tends to clean the engine when first used and removes deposits from the fuel lines which can clog fuel injectors. After switching to biodiesel most car manufacturers recommend changing the fuel filter to help prevent this. Use of this fuel leads to lower engine emissions while improving engine lubrication. Many government fleets on the federal and state level as well as utility fleets are now required to purchase 75 to 90 percent alternative fuel vehicles these days. Since biodiesel is the lowest cost alternative fuel option many of these fleets are converting to its use.

Diesel forms nearly 40% of the energy consumed in the form of hydrocarbon fuels, and its demand is estimated at 40 million tons per year. In the coming years as concerns about rising fuel prices and the lack of renewable energy sources rises the value of bio diesel fuel as a cheap renewable energy source will continue to rise.
