Municipal solid wastes incineration (MSWI) has been recognized as an effective treatment to reduce the volume of the MSW, while generating energy. However, disposal of the incineration residues becomes challenge, especially for countries with limited landfilling space. In this study, the feasibility of developing a green concrete product from MSWI residues and eventually reaching a waste-free incineration was investigated. The green concrete was composed of coarse bottom ash as aggregates and eco-cement as binder, the latter of which was exclusively derived from incineration residues clinkered at incineration temperature (1100 °C). The major reactive phases in eco-cement were chloro-ellestadite and belite, which possessed both carbonation property and hydration behavior. The green concrete was activated by carbonation curing to accelerate strength gain and facilitate carbon dioxide sequestration. Comprehensive environmental assessment tests validated the safe use of eco-cement and green concrete. This work had demonstrated the potential of reaching a waste-free incineration through green concrete production, where all the residues including incineration heat and flue gas carbon dioxide were used to their best advantages.
