During the bio-diesel transesterification process the polyhydroxyalcohol glycerol is generated in large amounts as the major waste product. For every tonne (= metric ton) of bio-diesel generated by this process, about 100 kilograms (100 kg) of glycerol waste is produced. The glycerol produced is traditionally used in pharmaceuticals, cosmetics, soaps, toothpaste, paints and other commercial products. The amount of glycerol in the U.S. market has increased because of bio-diesel production.
