Due to high quantities of animal fat resulted from leather industry, the necessity of a solution in order to neutralize the negative effects that appear by their discharge into the nature has led to continuous research in order to obtain the most suitable one for solving the environmental issue with energy recovery. Between combustion and chemical treatment, the combustion has been chosen in this study as being the most effective one, by technical and economical criteria. Before this combustion, there were perform...
