The objective of this work for evaluating the potential of biogas and methane productions and still and reductions in levels of total solids (TS), volatile solids (VS) and neutral detergent fiber (NDF) of the co-digestion anaerobic digestion in digesters fed with swine manure plus disposal of oil and lyophilized microorganisms. For assay development substrates were prepared containing 4% TS, consisting of swine manure, disposal oil (the proportions 8, 10 and 12% oil content in relation to the substrate TS), lyophilized microorganisms (Biol-2000 ® - concentrations of 10 g/m3 and 15 g/m3 ), water for dilution of this waste and inoculum for batch digesters supply. There was no significant difference with respect to reductions in TS, VS and NDF constituents, providing very significant reductions in average 54.14; 62.79 and 49.16% respectively. Regarding the potential of biogas production, the highest yields occurred in digesters supplied with 10% oil and 15 g/m3 of Biol®, being 0.43 and 0.54 L of biogas per kg of TS and VS added, respectively, similar results were found when assessed the potential for methane production, with higher values (0.22 and 0.27 L of methane per kg of TS added and VS, respectively) obitidos the same treatment. The inclusion of 15 g/m3 in Biol® substrate composition containing swine manure and 10% of oil improves the yields of biogas and methane.
