Anaerobic digestion of the Korean aged cow manure in anaerobic digester treating food waste and pig manure

Cow manure produced in Korea is usually mixed with plant-based bedding materials and left for several months on the floors of pens before being collected. It is not an attractive feedstock for anaerobic digestion in Korea. An attempt to co-digest the aged cow manure with food waste and pig manure using the spare capacity of the existing anaerobic digestion plant was investigated in this study.
