Abstract In order to utilize the sludge landfill gas effectively, production rate and production content of sludge landfill gas were predicted. The approximate formula of sludge organics for Bailonggang wastewater treatment plant in Shanghai was C28H52O16N4 using the normalized molar methods of elements. The potential of methane production predicted using chemometrics method and IPCC model were 60.6, 61.7kg/t (dry weight), respectively. The production rate of methane predicted using dynamics model method and IPCC model method were 13.3, 11.1kg/(t×a) (dry weight), respectively. The difference for the methane production rate of these two methods lies in the differences for the values of parameters. The methane production content predicted using chemometrics method and methane production rate predicted using dynamics model method was suit to reflect the actual situation. IPCC model was suitable for estimate the gas production content of a region or country as a whole from a macro perspective.
