Wani abu da Brazil ma yana da a copous yawa amma underuses ne glycerol, a byproduct na mai da kitsen saponification a cikin sabulu da wanka masana'antu, da kuma transesterification halayen a cikin biodiesel masana'antu.A wannan yanayin yanayin ya fi muni saboda glycerol sau da yawa ana watsar da shi azaman sharar gida, kuma zubar da manyan kundin yana da rikitarwa.
