Biodiesel (Greek, bio = life + diesel = from Rudolf Diesel) refers to diesel equivalent, processed from biological sources. Biodiesel is otherwise referred as “neat” fuel. It is a fuel derived from a chemical reaction of alcohol (methyl, ethyl, butyl, propyl, isopropyl) and vegetable or animal oils, fats, or greases. These oils or fats are chemically altered in order to use in any diesel engine, with little or no modification. A process called transesterification removes the glycerin component of the oil (which is a triglyceride molecule), resulting in a much thinner, or less viscous product, which stays down to much lower temperatures. It significantly reduces harmful pollutants, as well as carbon dioxide gas and reduces our vehicles contribution to climate change. Current oil and gas reserves are sufficing to last only a few more decades. The scarcity of known petroleum reserves will make renewable energy sources more attractive. To meet the rising energy demand and replace petroleum reserves, fuels, natural gas etc., Biodiesel is in the forefront of alternative technologies. The first record of Biodiesel usage was in 31st August 1937, by the University of Brussels, Belgium who conducted transesterification of vegetable oil using ethanol in order to separate the fatty acids from glycerol by replacing the glycerol with short liner alcohols. More recently Renault and Peugeot have approved the use of biodiesel in some of their own truck engines. In 1991, the European Community (EC) proposed a 90% tax deduction for the use of biofuels, including biodiesel. Now a days each of the plant are producing up to >1.5 billion gallons of fuel per year. The European Union accounted for nearly 89% of all biodiesel production worldwide in 2005. The present study is aimed at Synthesis of Biodiesel from Chicken Waste using Egg Shell as Catalyst.
