- Abstract
The objective of this study was to analyze the performance of agroindustrial residues from a food cooperative in the Taquari Valley (Rio Grande do Sul), submitted to the anaerobic biodigestion process to obtain biogas for energy purposes. The experiment was focused on the variation of the percentage of swine manure in a mixture of sludge from effluent treatment plants, allowing the evaluation of its interference or contribution in the quantity and quality of the biogas generated, since this residue is produced in greater volume and has great applicability in anaerobic digestion processes. The results indicated that the synergy between the combined substrates was positive. The best biogas production efficiency was obtained in the mixture with 60% swine manure and 40% of the sludge and blood mixture. It was found that, even requiring different hydraulic holding times, the higher biogas volumes in the blends were produced in the first days of the process. It is concluded that the codigestion of residual biomass is able to promote better yields in the production of biogas for its use as a renewable source of energy, when compared to the performance of the digestion of swine manure, which is a biomass typically used as a substrate for generation of biogas.
