It is well documented in the literature that enzymatic processing of oils and fats for biodiesel is technically

feasible. However, with very few exceptions, enzyme technology is not currently used in commercial-scale

biodiesel production. This is mainly due to non-optimized process design and a lack of available costeffective

enzymes. The technology to re-use enzymes has typically proven insufficient for the processes to

be competitive. However, literature data documenting the productivity of enzymatic biodiesel together

with the development of new immobilization technology indicates that enzyme catalysts can become cost

effective compared to chemical processing. This work reviews the enzymatic processing of oils and fats

into biodiesel with focus on process design and economy.
