| Description | Introduction Municipal solid waste incineration (MSWI) fly ash and heavy metals-bearing sludge are hazardous wastes that must be solidified and/or stabilized (S/S) before landfill disposal. Most metal-bearing sludges are high in Al2O3 and SO3 chemical composition and when combined with MSWI fly ash will result in the formation of Friedel’s salt and ettringite hydrate in the S/S matrix [1] which provides a better fixing effectiveness for heavy metals. The objective of this study was to use MSWI fly ash as a binding material for codisposing heavy metal-bearing sludges. The co-disposal effectiveness of the mix was evaluated by analyzing its physical and leaching properties as well as hydrate composition.
