The aim of the present study was to evaluate the effects of fuel recovery parameters as well as to determine the optimum conversion conditions. Municipal solid and liquid waste (MSLW) production and accumulation are global environmental issues. The waste products of a home include paper, containers, tin cans, aluminum cans, and food scraps, as well as sewage. Solid wastes can be utilized by direct combustion or converted to useful fuels and chemicals by pyrolysis and/or steam gasification processes. Sewage sludge can be converted to fuel briquette and organic fertilizer by the composting and briquetting processes. MSLW can also be evaluated in landfill gas production by anaerobic microbial decomposition. The yields of liquid and gaseous products from the municipal solid waste pyrolysis increase from 23.8 to 49.7% with increasing temperature from 584 to 683 K.
