Biodiesel is a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. Biodiesel is typically made by chemically reacting lipids with an alcohol producing fatty acid esters. Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products-methyl esters and glycerin. Biodiesel has many ecofriendly properties which are beneficial to us. The main benefit of biodiesel is that it can be described as carbon neutral. This means that the fuel produces no net output of carbon in the form of carbon dioxide. This effect occurs because when the oil crop grows it absorbs the same amount of CO2 as is released when the fuel is combusted.
