Biological conversion of biomass to methane has received increasing attention in recent
years. Hand-and mechanically-sorted municipal solid waste and nearly 100 genera of fruit
and vegetable solid wastes, leaves, grasses, woods, weeds, marine and freshwater biomass
have been explored for their anaerobic digestion potential to methane. In this review, the
extensive literature data have been tabulated and ranked under various categories and the
influence of several parameters on the methane potential of the feedstocks are presented.
