In this study the production of methane gas and the removal efficiency of nutrients in the anaerobic co-digestion facilitieswith food waste/food waste leachate (FWL), animal manure and food waste leachate (A-MIX), and sewage sludge andfood waste leachate (S-MIX) were investigated. The average amount of the theoretical methane production was 578.4CH4·L/kg·VSin from the anaerobic digestion facilities with FWL, 606.0CH4·L/kg·VSin from those with A-MIX and 570.0CH4·L/kg·VSin from those with S-MIX, respectively. The amount of the practical methane production was 350.7CH4·L/kg·VSin from the anaerobic digestion facilities with FWL, 379.5CH4·L/kg·VSin from those with A-MIX and 348.8CH4·L/kg·VSin from those with S-MIX, respectively. The nutrient compositions of FWL were 3.2g/100g for carbohydrates, 1.8g/100g for proteins and 1.9g/100g for lipids. The nutrient compositions of A-MIX were 0.4g/100g for carbohydrates,2.55g/100g for proteins 0.4g/100g and 0.7g/100g for lipids, respectively. The nutrient compositions of S-MIX were0.4g/100g for carbohydrates, 2.4g/100g for proteins 1.6g/100g and 0.4g/100g for lipids, respectively. The removalratio of carbohydrate was very high over 75% in all facilities and that of lipid was very low below 25%.
