Weathering of MSWI bottom ash with emphasis on the glassy constituents

Mineralogical characterization of municipal solid waste incineration bottom ash with an emphasis on heavy metal-bearing phases

“…However, the simulation is only based on the pH variation without considering the evolutionary process of the bottom ash constituents. MSWI bottom ash has been reported as being a complex inorganic assemblage mainly composed of fine materials, melt components, small quantities of metallic components, synthetic ceramics and stones, as well as unburned organic matter [1,[6][7][8][9][10][11][12]. Several complex silicates and oxides exist as primary melt components in bottom ash products, the characterization of which remain undetermined [13].…”

Characterization study of heavy metal-bearing phases in MSW slag

“…Through literature survey, we understand that a great deal of attention has been given to the investigation on leaching potential of toxic metals in ash and slag [3][4][5][6][7][8]. However, fewer studies have focused on the identification and characterization of metal-rich phases with respect to their spatial distribution, morphology and chemical compositions.…”

Chemical activation in view of MSWI bottom ash recycling in cement-based systems

“…The intrinsic reactivity of fresh incinerator bottom ash (BA) is well established (see, e.g., [1][2][3]). It originates from the fact that the bottom ash minerals formed under high-temperature combustion conditions are typically subjected to rapid cooling down to ambient temperatures during quenching downstream of the combustion unit.…”
