Bio Diesel from Waste Vegetable Oil

The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The indiscriminate extraction and consumption of fossil fuels have led to a reduction in petroleum reserves. Alternative fuels, energy conservation and management, energy efficiency and environmental protection have become important in recent years. The increasing import bill has necessitated the search for liquid fuels as an alternative to diesel, which is being used in large quantities in transport, agriculture, industrial, commercial and domestic sectors. Biodiesel obtained from vegetable oils has been considered a promising option. In this paper, an attempt has been made to produce biodiesel from waste vegetable oils and the properties of the produced biodiesel have been studied including its emission characteristics. A four stroke, single cylinder is used to study the emission and performance characteristics.The large scale production of Biodiesel and its economic aspects have also been discussed in brief.
