Anaerobic Digestion as an Effective Biofuel Production Technology

摘要: The methane produced from the anaerobic digestion of organic wastes and energy crops represents an elegant economical mean generating renewable biofuel. Anaerobic is a mature technology already used for conversion fraction municipal solid primary secondary sludge wastewater treatment plant. High yield up to 0.45 Nm3 CH4/kg volatile solids (VS) or 12,390 CH4/ha can be achieved with sugar starch crops, although these cultures are competing high quality land food feed crops. cultivation lignocellulosic on marginal set-aside lands more environmentally sound sustainable option production. obtained lower, 0.17–0.39 VS 5,400 CH4/ha, as its into facing same initial barrier production ethanol, e.g., hydrolysis Intensive research development efficient pretreatments ongoing optimize net production, which potentially greater than liquid biofuels, since whole substrate excepted lignin convertible methane. Algal biomass another alternative Their relatively potential (up fed) combined their higher areal productivity make them particularly attractive feedstock digestion-based biorefinery concept.
