Biodiesel is simple to use, biodegradable, and non-toxic in nature and, most importantly, it is free of aromatics, and sulfur compounds. It emits lower greenhouse gases and air pollutants, reduces toxic carbon-based emissions and can be used in most diesel engines. The increasing concern regarding greenhouse gas emissions through the use of fossil fuels is driving the growth of the biodiesel market. Biodiesel reduces the emission of greenhouse gases by up to 50% as compared to petroleum diesel; and also has low toxic and carcinogenic aromatic carbon content. The production of biodiesel by several countries has helped them in reducing their dependence on foreign oil reserves, as it is domestically produced, and can be used in any diesel engine with little or no modifications to the engine or the fuel system.
