Manufacturing BiodieselThere are a variety of products that biodiesel can be made from; although they are all very different they all produce the same end product.
![]() ![]() The process used to make biodiesel is a chemical process called transesterification, where glycerin is separated from fat or vegetable oil. The process of transesterification leaves biodiesel and one by product, the byproduct of this process is glycerin. The glycerin is not used in biodiesel but is used in cosmetics and wet cat and dog foods. Methyl-esters make up the biodiesel. Although biodiesel can be produced from vegetable oil, biodiesel and raw vegetable oil is not the same thing.
