Abstract

Accelerated population growth has led to an increase in the production of agricultural, industrial and agroindustrial waste, with the aggravating factor being incorrect disposal, causing a public health problem. In this sense, the objective was to evaluate the anaerobic digestion (AD) between bovine manure (BM), sewage sludge (SS) and water (W) in the proportions of 100:0 BM:SS, 0:100 BM:SS, 50:50 BM:SS and 50:50 BM:A to propose a solution to these environmental liabilities. The substrate was characterized for its physicochemical properties. The biogas generated due to the AD of substrates under MoAD and CoAD was analyzed for its weekly and cumulative production potential. In general, the mean values of the substrate characterization parameters were in the ideal range for biogas production. However, it was verified that with the CoAD between BM and SS, average values of the physical-chemical parameters were obtained, which favored a higher production of biogas with a shorter start-up time. Thus, it is concluded that the sewage sludge used as a codigestant of bovine manure stabilizes the organic matter and provides a liquid medium and microbial load for greater biogas production, in addition to being an excellent substitute for water.
