Enzymatic Production of Biodiesel and Fatty Acid Alkyl Esters    

The process combines immobilized lipase, inert solvent and technical innovation to produce biodiesel and other high value-added products. This enzymatic approach is efficient, low-cost and fast.


Unlike the chemical approach, this process can accept both triglyceride and fatty acid as feedstocks. In so doing, it eliminates the need for a costly refining process. The reaction is carried out in an inert solvent environment to protect the lipase from deactivation due to methanol/ethanol or glycerol. Normally, the reaction is done at room temperature. Pure biodiesel and pure glycerol can be obtained directly from the reactor after removal of inert solvent.

The main advantages include:
-no wastewater, no chemical waste, no toxic compounds involved
-safe, simple-to-operate and cost-effective
-degummed crude is all that is needed. The oil can be virgin, used, vegetable or animal sourced
-can produce biodiesel at a cost lower than diesel
