Research on the Influence of Kitchen Waste Separation on MSW Incineration

With the acceleration of urbanization and industrialization, the amount of MSW in China generated is growing fast, while the pollutants generated in the disposal process of MSW has gradually attracted people’s attention. This paper presents the generation and composition status of MSW in China, summarizing the problems during MSW incineration disposal, providing an assumption of kitchen waste separation and using heat balance calculation to analysis the impact of kitchen waste separation on MSW incineration. Results shows that after kitchen waste separated from MSW, the amount of MSW reduced obviously, moisture content dropped, calorific value improved, auxiliary fuel is not need to ensure the proper incineration process and combustion efficiency improved; meanwhile, the generation of greenhouse gases and air pollutants is reduced significantly. Overall, the separation of kitchen waste not only reduced the difficulty and handling stress of MSW incineration, but also improved the incineration efficiency, reduced the generation of pollutants during incineration process.
