Abstract
Municipal solidwaste incineration (MSWI) is a net contributor to climate change due to fossilcarbon dioxide (CO2) emissions to air from combustion of the waste.Fossil CO2 emissions are not offset when the energy recovered fromMSWI substitutes energy production from non-fossil energy sources. Carboncapture and storage (CCS) via monoethanolammine (MEA) can reduce the climatechange impacts of MSWI by capturing and storing the CO2 in the fluegas. However, CCS requires steam and can considerably reduce energy recoveryfrom MSWI. This paper summarizes the potential climate change impacts ofintroducing MSWI in a range of MSWI configurations with different energyrecovery, under different waste composition and energy system scenarios. Introducing CCS in MSWI lowers the climate change impacts of MSWI by700 kg CO2-eq per tonne of waste incinerated. Electricity recoverylowers between 30 to 50%, but post-capture flue gas condensation allows furtherheat recovery in MSWI plants connected to district heating. MSWI with CCSprovides net climate change savings for all MSWI configurations assessed, forall waste composition and energy systems assessed in the study.
