As the end-of-pipe control for sustainable consumption and production, it is necessary to develop more sustainable options for solid waste management to reduce the risk of secondary pollution. This chapter presents a system dynamics (SD) approach to model the variation of the economic return of a municipal incineration plant in different scenarios, to investigate the maximum potential of evaporating waste leachate while using landfill gas as a combustion improver, and thus promote the sustainable waste disposal. Since the public may have different perceptions of waste disposal, ‘Not in My Backyard’ (NIMBY) conflicts may arise due to their individual rationalism. The Chapter further shows an evolutionary game theoretical analysis to mitigate the conflicts of interest among the local government, the operational enterprise and the  residents. To support the process safety management of hazardous materials, the Chapter demonstrates a decision support system (DSS) to aid the emergency management of sudden environmental pollution incidents, to minimize casualties and property losses.
