Biodiesels early growth was careful and deliberate, with a focus on sustainability for the industry. It is made from an increasingly diverse mix of resources including agricultural oils, recycled cooking oil and animal fats and meets the strict specifications of ASTM D6751. This involves vegetable or animal fats and oils being reacted with short-chain alcohols (typically methanol or ethanol).The alcohols used should be of low molecular weight. Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. It is a simple choice and a smart solution that results in a better fuel for your home and the environment. See also renewable energy. Biodiesel is America's first Advanced Biofuel. The process of preparing biodiesel is termed as transesterification. Key words: Biodiesel, used vegetable oil, transesterification, alcohol.
