I note that the Coco diesel doesn't claim to be methyl esters. Digestion by micro-organisms is an obvious step in Oil extraction if the product doesn't need to be edible. It is quite likely that some yeast like bugs would target the glycerol part of an oil molecule, releasing FFAs. In fact any bug that causes rancidity would be expected to do just that. Many of the countries that produce excess coconut require stationary desiels that can easily be converted to SVO and coconut has the advantage of requiring next to no refining compared to other vegy oils that contain gums etc.. Hanns has worked for some time on practical alternatives for direct oil extraction from fresh coconuts-When he returns fron New Guinea I will refer this thread. Regards from Harry
