The transport sector and the replacement of fossil gasoline and fossil diesel oil is the main object of ethanol as well as of FAME production.
So far, the total amounts of ethanol and biodiesel are minor as compared to the total amounts of fuel used in the transport sector but as volumes grow, there may be good reason to consider the feedstock for both fuels from an ethical point of view.
