Different possibilities of extracting biodiesel from fat residues generated on farm livestock: chicken, pork, and bovine fat, were studied. To do this, the variables molar ratio alcohol/animal fat and amount of catalyst are analyzed, since those are the ones which most affect the quality of biodiesel when assessing the characteristics and efficiency of the transesterification reaction. The efficiency in the poultry waste material extraction process is 70.5%, and in pork fat is 90%, reason why they are proposed as feasible alternatives from the technical standpoint, allowing the recovery of this organic waste, thus alleviating the pollution generated by this type of industry. From the characterization performed on chicken and pork fat, it has been established that this raw material has low acidity which ensures a high degree of transesterification, taking into account that it had 96% efficiency from chicken fat and 91.2% from pork fat. From the synthesized biodiesel Chromatographic analysis it was found that the most common fatty acid was oleic acid.
