What is Biodiesel?

Biodiesel is typically produced by a reaction of oil or fat with a short chain alcohol such as methanol or ethanol in presence of a catalyst (potassium hydroxide) to yield mono-alkylesters of long chain fatty acids (fatty acid methyl ester, or FAME). This reaction is a transesterification and yields glycerol as a valuable coproduct.
