The possibility of obtaining oil from plant resources has aroused a great interest and in several countries, vegetable oil after esterification being used as ‘Biodiesel’. The biodiesel can be used as 20% blend with petrodiesel in existing engines without any modification. Both the edible and non edible vegetable oils can be used as the raw materials for the biodiesel.
