This study conducts an environmental and economic evaluation of the use of CO2 from Japan’s waste incineration facilities in Carbon Capture Utilization and Storage (CCUS) facilities. Our analysis shows that introducing CCUS to manage CO2 from a 300 t/D waste incineration facility can reduce CO2 emissions. However, even under a cleaner energy vision, the CO2 emissions of the whole system are still positive, making it difficult to achieve the carbon neutrality target. On the economic side, introducing CCUS increases expenses, resulting in greater losses for the overall waste incineration business than if it exclusively operates incineration only.

摘要

This study conducts an environmental and economic evaluation of the use of CO2 from Japan’s waste incineration facilities in Carbon Capture Utilization and Storage (CCUS) facilities. Our analysis shows that introducing CCUS to manage CO2 from a 300 t/D waste incineration facility can reduce CO2 emissions. However, even under a cleaner energy vision, the CO2 emissions of the whole system are still positive, making it difficult to achieve the carbon neutrality target. On the economic side, introducing CCUS increases expenses, resulting in greater losses for the overall waste incineration business than if it exclusively operates incineration only.
