Feasibility Study on Installing Carbon Capture Systems at Waste-to-Energy Plants for 2050

Abstract

This paper examines the feasibility of implementing CO₂ capture facilities in municipal solid waste incineration plants to achieve carbon neutrality by 2050. Analysis showed that facilities processing more than 375 tons of waste per day can be energy self-sufficient when equipped with CO₂ capture systems. Calculations indicated that CO₂ capture facilities need to be installed in at least 33 facilities to achieve carbon neutrality. Three scenarios for facility consolidation through regional integration were examined. The results demonstrated that carbon neutrality could be achieved through regional integration in metropolitan areas and within prefectures. Furthermore, economic evaluation of CO₂ capture facility implementation confirmed that investment recovery is possible given certain CO₂ emission credit prices.
