The invention relates to a method for obtaining fuels from vegetal 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.
L'invention concerne un procédé de production de combustibles à partir de déchets gras végétaux et/ou animaux contenant non seulement les graisses et/ou huiles mais aussi des acides gras libres. Les acides gras libres contenus dans les déchets gras peuvent réagir avec au moins un alcool polyvalent en présence de catalyseurs enzymatiques et neutres solides à des températures de réaction supérieures à 220 °C de manière à entraîner une estérification des acides gras libres.
