Abstract: Incineration is the main treatment method for domestic waste, and a amount of greenhouse gases will be emitted during the incineration process. Taking a domestic waste incineration plant in Beijing as an example, greenhouse gas emission (GGE) accounting was carried out based on the entire process of domestic waste incineration. The results indicated that the CO2 equivalent intensity of GGE from domestic waste incineration was approximately 0.55 t/t. The domestic waste incineration had good potential for carbon reduction with 0.32 t/t of carbon storage capacity. From the perspective of production process, GGE from the treatment and utilization stages accounted for 99.00% of the total emissions. The contribution of CH4 and N2O was 10.81% in the processing stage. This study estimated that using domestic waste incineration to generate electricity was expected to reduce GGE by 99.842 1 million tons per year nationwide, with significant pollution and carbon reduction effects. This is of great significance for achieving the goal of carbon peak and carbon neutrality.

Key words: the entire process, domestic waste incineration, greenhouse gas, carbon emission, carbon storage
