Biodiesel is defined as the mono-alkyl esters of fatty acids derived from vegetable oils or animal fats. We'll talk more about what that means later. In simple terms, biodiesel is the product you get when a vegetable oil or animal fat is chemically reacted with an alcohol to produce a new compound that is known as a fatty acid alkyl ester. A catalyst such as sodium or potassium hydroxide is required. Glycerol is produced as a byproduct. The approximate proportions of the reaction are:
100 lbs of oil + 10 lbs of methanol 100 lbs of biodiesel + 10 lbs of glycerol
Soybean oil and methanol are the most popular feedstocks in the United States. Soybeans are a major U.S. crop and government subsidies are available to make the fuel economically attractive to consumers who need or want to use a nonpetroleum-based fuel. Biodiesel from soybeans is sometimes called soydiesel, methyl soyate, or soy methyl esters (SME). In Europe, most biodiesel is made from rapeseed oil and methanol and it is known as rapeseed methyl esters (RME). The University of Idaho has done considerable work with rapeseed esters using ethanol, which produces rapeseed ethyl esters (REE).

It definitely has to be beneficial, as we are all aware, fossil fuels woudnt last for ever, It is imperative that we find alternative methods to facilitate locomotion, it could be in form of fuel or non conventional resources like solar energy, wind, whatever.
In this scenario, if there is a resource which can be cultivated then it becomes a perennial source of energy. It might be crude at first but with continuing research the efficacy and efficiency of this fuel could improve thereby helping mankind to go slow on natural resources.

It's a boon for now...but will soon become a bane as the price of used cooking oil surpasses light sweet crude.
