[Abstract]

State and control methods of CH₄ and N₂O emission from solid waste disposal facilities were studied by means of in situ observation, laboratory experiments, published data and mathematical analysis. Firstly, the importance of the complete combustion in mechanical batch combustion type incineration facilities for the CH₄ emission control is confirmed by a in situ observation. Secondary, in night soil treatment plants with high loading dinitrification processes, it is suggested that some operation manners, such as the quality of substrate and duration of aerobic/anaerobic condition in reactor(s), would mainly control N_{2O emission. Thirdly, at MSW landfill sites, the control of air filled porosity of cover soil is important for the CH4 emission control by means of regulating the CH4 consumption of soil.}
