Process Simulation of enzymatic biodiesel production -at what cost can biodiesel be made with enzymes?

The industrial production of biodiesel has had a very turbulent lifetime due to drastic changes in prices of raw materials and fossil fuels as well as regulatory changes and produced amounts of biodiesel.

Biodiesel production is carried out by various forms of catalysts, but industrially only chemical homogenous catalysts are used on large scale.

Smaller pilot plants with enzymatic catalyzed production are reported, but not to a very large extent. In order to evaluate the potential and remaining obstacles of introducing enzymes as the preferred industrial catalyst, analysis of economical as well as environmental impacts of the alternative process must be evaluated towards the conventional process.
With process simulation tools, an evaluation will be carried out looking at what it will cost to produce biodiesel with enzymes. Different scenarios will be taken into account with variations in raw material prices, process designs and enzyme cost and performance.
