ABSTRACT
Produced from oleaginous plants, animal fats, used vegetable oils or algae, biod-iesel is a renewable transport fuel used in diesel-run cars. In Europe, biodiesel can be marketed in 5-7 per cent blends in diesel in normal cars, while in captive fl eets for public transportation, biodiesel can be blended from 30-100 per cent with some engine and fi lter modifi cations.
