In Belgium a novel high rate anaerobic composting process with biogas has been developed as an alternative to aerobic systems, producing a commercial dry compost and 60 to 95 cubic metres methane per ton of municipal solid waste. This is a high value energy source simultaneously yielding a stabilized end product. The process was developed so that digestion could take place at 25 to 35% total solids, thus reducing the amount of water needed to dilute the waste, decreasing the digestor volume and cutting transportation costs. The end product is odorless and stable. High rate anaerobic composting of MSW can be combined with sewage sludge stabilization. Manure, vegetable or fruit wastes can be co-treated in certain proportions as required. About 15 to 20% of the energy produced is transformed into electricity and heat and consumed as the waste disposal plant itself. 120 to 140 US $ worth of methane gas and compost can be produced per cubic metre of reactor per year, making anaerobic composting economically attractive.
