Abstract: Biodiesel consists monoalkyl esters of long chain fatty acids. It is produced from vegetable oils or fats either by chemi-cal transesterification or by lipase-catalyzed transesterification with methanol or ethanol. Biodiesel is a green fuel and can be used as a blend with diesel or alone. Either way, it does not require any modification in engine design or storage facilities. The enzymatic process offers several advantages over the chemical routes. The handicap of increase in process cost because of the cost of the enzyme can be overcome by using efficient production process for enzyme and using reusable derivatives of enzymes, such as immobilized enzyme. Numerous strategies available in the area of non-aqueous enzymology can be ex-ploited during the enzymatic alcoholysis for biodiesel production. Some of the technical challenges and their possible solu-tions are also discussed.
