Biodiesel and bioethanol are currently the only fuel replacer. Its high cost opposed to crude oil should be compensated by other advantages in production mainly from waste materials that are searched for. Therefore, we discuss the blend of biobutanol with biodiesel produced from animal fat and other waste biomass as a fuel for use in diesel engines from the point of view of density, kinematic viscosity, CFPP and oxidation stability improving the properties of FAME in this article. Also the blend of bioethanol and biobutanol can be produced from waste products. Biobutanol and bioethanol are compared. The properties of biodiesel from waste fats are influenced by this raw material, but they are available in large quantities. Therefore, the ability of biobutanol to improve the parameters of biodiesel is tested and described in the experimental part of the article. Animal byproducts from processing of pork were subject to thermal pressure sterilization and further processed. The next step is then followed by a classical method for producing fatty acid methyl ester and adding biobutanol. The standard EN 590 for diesel and EN 14 214 for FAME were used for evaluation of the fuel parameters. Limited quantity of biobutanol in biofuel improves its parameters minimizing the negative effects of methyl esters from waste animal fats.
