Abstract: The entire life cycle of a municipal solid waste (MSW) oxy-fuel incineration power plant was evaluated using the method of life cycle assessment (LCA) to identify and quantify the fossil energy requirements and environmental impacts. The functional unit was 1000kg (1t) MSW. During the life cycle, the saving standard coal by electricity generation was more than diesel consumption, and the effect of soot and ashes was the greatest among all calculated categorization impacts. The total weighted resource consumption and total weighted environment potential of MSW oxy-fuel incineration were −0.37 mPR90 (milli person equivalent) and −0.27 PET2010 (person equivalent), better than MSW incineration with CO2 capture via monoethanolamine (MEA) absorption. The sensitivity analysis showed that the electric power consumption of air separation unit (ASU) was the primary influencing parameter, and the influence of electric power consumption of CO2 compressor was secondary, while transport distance had small influence. Overall, MSW oxy-fuel incineration technology has certain development potential with the increment of MSW power supply efficiency and development of ASU in the future.
