Innovation - Biodiesel, the methyl ester of fatty acid, has been accepted as a renewablesourced alternative to fossil-derived diesel fuel. Today, in many parts of the world, biodiesel is already blended with diesel fuel upwards of 5%. As demand for this fuel increases, so do raw material prices. Since the raw material prices account for approximately 90% of the manufactured biodiesel cost, manufacturers are constantly looking for ways to reduce their raw material cost burden.
