The Utilization of Mswi Fly Ashes in Cement Production and Its Impact on Heavy Metal Contents in Cement
SUMMARY: The disposal of fly ashes from municipal solid waste incineration (MSWI) is becoming a growing environmental issue in Europe. In order to avoid landfilling and recycle MSWI fly ashes, initiatives aim to recycle them in cement production. While numerous studies have analyzed the impact of MSWI ashes application on the concrete quality and the leaching of potentially hazardous heavy meta...
متن کاملFormation of Humic Substances in Weathered MSWI Bottom Ash
The study aimed at evaluating the humic substances (HSs) content from municipal solid waste incinerator (MSWI) bottom ash and its variation with time and the effect of temperature on HSs formation. The process suggested by IHSS was applied to extract HSs from two different bottom ash samples, and the extracted efficiency with NaOH and Na4P2O7 was compared. MSWI bottom ash samples were incubated...
متن کاملProperties of Concrete with Municipal Solid Waste Incinerator Bottom Ash
The appropriate utilization of Municipal Solid Waste Incineration (MSWI) residues is a worldwide studied topic over the last decades. One of the possibilities is to use MSWI ashes in concrete production, as it is done with coal combustion products. The bottom ash features the most convenient composition for this purpose, and it is available in highest amounts among the MSWI ashes. Untreated bot...
متن کاملEffect of carbonation on the leaching of organic carbon and of copper from MSWI bottom ash.
In Flanders, the northern part of Belgium, about 31% of the produced amount of MSWI bottom ash is recycled as secondary raw material. In view of recycling a higher percentage of bottom ash, a particular bottom ash fraction (Ø 0.1-2mm) was studied. As the leaching of this bottom ash fraction exceeds some of the Flemish limit values for heavy metals (with Cu being the most critical), treatment is...
متن کاملLeaching Behaviour of a Glass Produced from a MSWI Bottom Ash
This paper is mainly focused on the characterisation of a glass material (GM) obtained from the thermal treatment of a bottom ash (BA) produced at the Municipal Solid Waste (MSW) incineration plant of Valorsul. By melting the BA at 1400oC during 2 hours, and without using any chemical additives, a homogeneous black-coloured glass was obtained. The thermal and mechanical properties of this glass...
