The effectsof waste composition,C/ N,inoculums,temperature,pHlevel,total solids,organic loading rate and mixing on anaerobic digestion were discussed in detail. The current classic anaerobic digestion processeswere introduced and illustrated by the case study. The advantage and disadvantage of processes were compared. The current drawback of anaerobic digestion of BOFMSW and integrative management of MSW were directed and the research direc鄄 tions of anaerobic digestion of BOFMSW in Chinawere
