Biodiesel FAQ 2. What is biodiesel?
Biodiesel is an efficient and cleaner burning alternative fuel. It is produced by chemically removing glycerin from vegetable oil and replacing it with alcohol from (usually) Methanol in the presence of a catalyst. The catalytic agent used for the chemical reaction – called transesterification, is either lye (sodium hydroxide – NaOH, also known as caustic soda) or potassium hydroxide (KOH). The reaction also produces Glycerin – a by-product that can be used for making soap and other useful products. Biodiesel FAQ 3.
