摘要

The aim of this work was to evaluate the amount of CO_2 that could be sequestered with a view to decrease greenhouse gas emissions and investigate the feasibility of modernizing some specific properties of the municipal solid waste incineration bottom ash with accelerated carbonation. Municipal solid waste incineration (MSWI) fly ash and bottom ashes are the byproducts of the incineration combustion process. We collected the different samples from four incineration plants located in Seoul. Some of the Korean MSWI byproducts contain heavy metals. Here, we reported encapsulation effect of some heavy metals such as arsenic (As), chromium (Cr), cadmium (Cd), lead (Pb), and nickel (Ni) in MSWI ashes by accelerated carbonation process. The carbonation reaction would promote CO_2 sequestration. In this paper, we reported the simultaneous CO_2 sequestration of municipal solid waste incineration byproducts and encapsulation studies of heavy metals. The investigations were carried out at the bench scale. Finally, an efficient removal of heavy metals (90-95%) was achieved.
