Biodiesel is used to refine automatic vegetable oil and is widely used in tractors, trucks and ships. It refers to oil crops such as soybean, rapeseed, cotton, palm, wild oil plant and engineering micro algae and other aquatic plant oils and animal fats, food waste oil as raw oil by ester exchange and thermal chemical process can replace petroleum diesel made of renewable diesel fuel.
                    Excellent performance of biodiesel made by biological diesel engine exhaust emission index not only meet the current standard of euro II, meet will be enacted in Europe even more stringent European Ⅲ emissions standards. And because biodiesel combustion emissions of carbon dioxide is much lower than when the carbon dioxide absorbed by the plant growth process, thus improving due to carbon dioxide emissions of global warming harmful to human's major environmental problems. So biodiesel is a real green diesel.
