In the present world of increasing population, pollution and price of fuel requires an alternate fuel which is environment friendly. Since last century many researches have been conducted on the production processes of an alternate fuel that is Biodiesel, whose cost is less and the best substituent for non-renewable fossil fuels. This study compares the different biodiesel production processes from Phase 1 to Phase 5. Tran’s esterification process is the best method for the production of biodiesel which is widely used. And hence all the methods in this study are respect to Tran’s esterification.

Trans’ esterification, Biodiesel, catalyst, Carbon neutral, Greenhouse gases.
