Peter, Roughly, bank of ~95% yield upward, depending upon the method used.
Ethanol in the production of ethyl esters (biodiesel) requires much attention to keeping the alcohol anhydrous. Other than that, the process is similar to when using methanoll. Yes, it is more environmentally friendly in comparison to methanol. But it also has that greater propensity to absorb water, which is one of the last things you would want in the manfacture of biodiesel. It can be done, and by all accounts done easily with the appropriate equipment and precautions in place. Keith has a pretty tight rein on ethanol data and resources. He would best be able to direct you on a path down that road.
