Using Non -Edible Vegetable Oils for Fuel can Reduce Toxic Emmision Resulting from Use of Fossil Fuel

YELLOW OLEANDER SEEDS

 

Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. Recently, there are researches designed to harness oil of non-edible nature for the production of the biodiesel. However, large amount of non-edible oils and fats are available. The term biodiesel, was first introduced in the United States in 1992 by the National Soy Development Board presently National Biodiesel Board (NBB), which has pioneered the commercialization of biodiesel in the USA (Ramadhas, et al., 2004).

The growing concern due to environmental pollution caused by the conventional fossil fuels and the realization that they are non-renewable have led to search for more environment friendly and renewable fuels. (Balusamy and Marappan, 2007). Among various options investigated for diesel fuel, biodiesel obtained from vegetable oils has been recognized world over as one of the strong contenders for reduction in exhaust emissions.

Worldwide, biodiesel production is mainly from edible oils such as Soyabean,

Sunflower and Canola oils that compete with the demand for human consumption. However, there are abundance of forest and plant based non-edible oils available in Nigeria such as Pongamia pinnata (karanja), Jatropha curcas (jatropha), Madhuca indica(mahua), Shorea robusta (Sal), Azadirachta indica (neem) and Heveabraziliensis (rubber). This has stimulated recent interest in alternative sources to replace petroleum based fuels.
