Today world is facing many environmental problems, which had adverse effects on the mankind. Global warming and coming crisis of natural energy sources are most important indications. If these problems are not solved at right time then it can be harmful for both developed and developing nations. Several companies with high consumption of petroleum products are now looking for alternatives to petroleum products.

Bio Diesel has several advantages due to which it is considered better than regular fuel. It increases transportation energy crisis mainly in farming and transportation sectors. Bio diesel has high lubricity but lower energy content than regular diesel. It is renewable, domestic, clean and can be based on a variety of vegetable feedstock, and indicated long-term maintenance reductions. Bio diesel is also environment friendly made from carbon dioxide neutral, low sculpture, non-toxic, biodegradable and vegetable products. It helps to decrease NOx emissions.

Biodiesel runs in any conventional unmodified diesel engine. Pure biodiesel increases engine's life, since it does not leave any deposits. The use of biodiesel can extend the life of diesel engines because it is more lubricating than petroleum diesel fuel while fuel consumption, ignition, power output and engine torque are unaffected.

Biodiesel can be made from renewable oilseed crops such as soybeans, rapeseed, and cottonseed and mustard seed. Biodiesel can also be made from imported feedstock such as palm oil. It provides whole range of new materials as by products that can easily replace many non-friendly materials, and leaving coal as a commodity that could be used for other optional safe and useful manufacturing processes that do not pollute atmosphere. Biodiesel is 11% oxygen by weight and contains no sulphur.

Bio diesel reduces the particle pollution and the amount of hazardous materials in vehicles exhaust fumes. Bio Diesel has good greenhouse effect on the environment. Combustion of biodiesel alone provides over a 90% reduction in total unburned hydrocarbons and a 75-90% reduction in aromatic hydrocarbons. Biodiesel is safe to handle and transport because it is as biodegradable as sugar, 10 times less toxic than table salt and has a high flashpoint.

Above described reasons are just a few benefits of bio diesel. Due to the benefits and advantages over other conventional fuels, bio-diesel is becoming a favorite alternative source of energy.
