The technical definition of biodiesel is a fuel suitable for use in compression ignition (diesel) engines that is comprised of fatty acid monoalkyl esters derived from biologically produced oils or fats including vegetable oils, animal fats and microalgal oils.
Biodiesel is an alternative fuel which can be made using a simple chemical process from waste vegetable oil. It can be used directly in any diesel engine, either neat or mixed in any ratio with petroleum diesel.
It is a green fuel, does not contribute to the carbon dioxide (CO2) burden and produces drastically reduced engine emissions. It is non-toxic and biodegradable.
Biodiesel has a much higher lubricity than petroleum diesel and its use can prolong engine life
