The Biodiesel is an alternative fuel which can be used in place of fossil fuels. It is manufactured from vegetable oils, recycled grease, algae, and animal fat. It is produced through a chemical process called transesterification, in which glycerine is separated from the vegetable oil or fat. It can be seen as alternative to conventional fossil fuels.
Benefits of Biodiesel :-
Biodiesel is a renewable fuel. It can be used in diesel engines with little or no modification. It can be produced locally. It is biodegradable, sustainable, non-toxic environment friendly fuel. On burning, it emits 60% less carbon dioxide (CO2). The energy produced by biodiesel on combustion is approximately 90% of that of energy produced by petroleum diesel. It is also used in non-engine applications such as to remove paint etc. Byproducts–methyl esters and glycerine obtained during production of biodiesel can be used preparation of soaps and other products
