The world is confronted with the twin crisis 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 because of its environmental benefits and the fact that it is mad from renewable resources. The cost of biodiesel however is the main hurdle to commercialization of the product. The used-frying oils are used as raw material for the production of biodiesel, thus helping to reduce the cost of water treatment in the sewerage system and generally assisting in the recycling of resources. The main objectives of the present study were to produce biodiesel from waste vegetable oil collected from sweet shops using Base-catalyzed Transesterification so as to reduce the overall cost of biodiesel. The physico-chemical properties of prepared biodiesel were found to be comparable to those of diesel and conforming to international standards. The transesterification reaction is affected by reaction temperature.
