Gasification is a promising alternative technology in solid waste management for megacities. It can reduce the volume of solid waste and recover heat and value-added products from this process. The feasibility test on co-gasification of different solid wastes with woody biomass has been conducted in this work using a 10 kW down-draft gasifier. Food waste, horse manure, chicken manure and sewage sludge mixed with wood chips in different ratios were fed to the reactor continuously at the rate of 10 kg/h. The temperature in combustion and reduction zone was 900 °C and 850 °C respectively. In-situ analyses of the produced syngas were conducted using a gas analyser before the gases were burned in the chimney. The syngas composition varied with the type and ratio of solid waste due to difference in ash content, elemental composition and solid structure.
