WebFeb 21, 2012 · This work investigated the possibilities of immobilizing incineration fly ash by applying different processing methods. Direct sintering of fly ash at 1050 °C produced material with increased resistance to leaching; however, the high content of halides prevented the achievement of appropriate strength. WebMunicipal solid waste incineration (MSWI) fly ash (FA) is classified as hazardous waste and requires special treatment prior to landfilling due to its high levels of alkali chlorides and heavy metals. In this paper we presented and discussed a novel method of converting FA into an inert and non-haza …
