摘要

The present disclosure relates to a method for obtaining fuels from vegetable and/or animal fat waste which contain, in addition to fat and/or oils, free fatty acids. The free fatty acids contained in the fat waste are reacted at reaction temperatures of above 220° C. with at least one polyvalent alcohol in the absence of enzymatic and solid neutral catalysts so as to produce the esterification of the free fatty acids.
