Over recent years, increased environmental awareness and stringent regulatory codes have significantly influenced the way we manage municipal solid waste (MSW). Incineration has become a widely accepted alternative to conventional landfilling. However, this method generates unstable bottom and fly ash residues. Fly ash is regarded more hazardous on account of its fine size and highly toxic constituents, and, therefore, requires further inertisation treatment prior to disposal. Vitrification is very effective in the containment of fly ash. This rather costly, energy-intensive method converts...
