Pure bio diesel fuel is available in some gas stations in Germany. And some manufactures are supporting the use of bio diesel in their car. Yet there are many manufacturers who do not accept bio diesel as fuel. They encourage mixing 30 % bio diesel to ordinary diesel that can be used to run the car.

Bio diesel can be produced from algae, vegetable oils; animal fats etc and it can be manufactured locally in any country. You can use pure bio diesel or use it along with petrol or diesel to run the vehicles. It is proved that bio diesel reduces engine's wear and tear. It is mostly used in European countries.

for extracting fuel and the remaining parts like leaf, barks etc for industrial and pharmaceutical purposes.
