However, the high price of this alternative fuel poses major barriers toward its widespread commercialization.1,2 As a consequence, biodiesel in the US has been restricted to specific industries such as refining, gas processing, petrochemical and chemical industries, where environmental and energy security concerns, which are subject to legislation, supersede economic aspects.
