This study assessed the feasibility of the anaerobic codigestion of hog and poultry waste. Anaerobic batch tests were performed using hog and poultry wastes in various proportions. Treatments that received both wastes produced higher yields of biogas, up to 200±30 mL/g volatile solids (VS) destroyed, and . methane, up to 130±20 mL/g VS destroyed, compared to either waste alone. The apparent complementation of the two wastes may reflect the absence of an added inoculum during the test. Keywords: agricultural waste, animal waste, anaerobic digestion, methanogenesis, waste treatment.
