Evaluación de la eficiencia de biochar obtenido mediante pirólisis de residuos avícolas, y lodos de depuradora.

Abstract

The transformation of natural resources generates waste that, due to uncontrolled accumulation and dumping, contributes to the appearance of vectors and diseases, as well as negative environmental impacts. In this project it is proposed to evaluate the efficiency of biochar obtained by thermal pyrolysis of poultry residues and sewage sludge. For this, the biochar of poultry residues (MBG1, MBG2 and MBG3) and biochar of sewage sludge (MBLD1, MBLD2, MBLD3) was obtained in a BAUJAHR batch reactor, under optimal operating conditions determined by a pilot test. Each sample was operated at a temperature of 300 ° C10 ° with a residence time of 30 minutes and in an inert atmosphere. Subsequently, a physical-chemical characterization of the biochar samples of poultry residues and biochar samples of sewage sludge was carried out. With the statistical software IBM SPSS 19, the characterization values of the biochar samples of each residue were compared with the parameters of a commercial biochar, each one pivoting to determine its efficiency. It was established that the samples of both types of biochar are efficient to be used as agricultural amendments, due to their nutrient content. It is recommended to apply these two types of biochar in crops, to evaluate their behavior in the soil and in the growth of the plants.
