This research project focuses on the utilization of Municipal Solid Waste Incineration (MSWI) Residues. About 90% of the municipal solid waste is incinerated in Taiwan, producing a huge amount of MSWI residues each year. However, Taiwan is highly urbanized and industrialized, and its disposal landfill area is scarcity. Therefore, the waste minimization is an urgent target for sustainable waste management.
The reuse of MSWI residues, including bottom ash and fly ash, should be developed to solve the problems of waste disposal. In this research, MSWI bottom ash was used as a resource again, and its utilization was categorized into three promising ways: sub-base layer, bituminous concrete and controlled low strength materials (CLSM). On the other hand, MSWI fly ash formed a melted-solidified slag under the melting process at the temperatures of 1100oC~ 1400oC, which was reused as a replacement for the fine aggregate in construction engineering.
Furthermore, since the demand of reused MSWI residues is much more than the supply, the marketability of the reused MSWI residues may not be a problem in the future. This research project also concluded a ‘ reused materials protocol’, as a recommendation for the future legislation.
