This study compares the environmental impacts of present PM and FW management strategies with an alternative co-digestion scenario. The co-digestion scenario performs better in most environmental impacts, and the N availability of the digestate is superior as well. Hotspots greatly influencing the environmental impacts are identified and mitigation methods are proposed. A low FW proportion in the co-digestion scenario cannot offset the negative impacts caused by the introduction of FW. For a farm with a PM production of 16,000 t/yr, at least 2000 t/yr FW is needed to ensure a negative GWP. These results can provide practical references to pig farmers, the gas industry and policy makers.
