Abstract

—Co-digestion of different mixtures of poultry manure, swine manure, and sawdust for biogas production was investigated. The substrate mixtures varying in their contents of carbon/nitrogen ratios (20:1, 25:1, and 30:1) were subjected to anaerobic digestion at ambient temperature for 42 days in a batch-type digestion experiment. The results showed that anaerobic digestion of the mixture of poultry manure and swine manure adjusted with sawdust and water to attain carbon-to-nitrogen ratio of 20:1 and 8% total solids at an average ambient temperature (30.4±1.52oC), average digester temperature (39.9±5.90 oC), and average digester pH (6.75±0.180) yielded optimum biogas (266.9±294.26 cm3/day). It was concluded that codigestion of poultry manure and swine manure for biogas production provides a sustainable route for alleviating the environmental nuisance otherwise caused by non-disposal of the livestock waste.
