Anaerobic digestion and co-digestion processes of vegetable and fruit residues: Process and microbial ecology

► Methane production under the specific conditions in Mexico City was demonstrated. ► Enhanced performance was achieved with pH control and nitrogen addition. ► Co-digestion of FVW with meat residues allows high and stable performance (30L). ► The microbial population in the AD system during optimal performance was determined. ► Bacterial and Archaea populations were correlated with its function in the AD system.
