Abstract: Increasing public concern regarding potential health problems due to improper waste disposal practices and the introduction of landfill taxes have induced the practice of incineration. Presently, all UK incinerators have to meet very strict emission levels. The municipal solid waste (MSW) fly ash generated has to be managed very carefully as it is enriched with toxic organic micro pollutants and heavy metals. The aim of the present work is to describe briefly a novel thermal technology, known as the ash detoxification process, that has been successful not only in the destruction of the toxic organic components, but also in the fixation of the heavy metal content to form an unleachable material.

Keywords: thermal technologies; heat regeneration; incineration; fly ash residues; the ash detoxification process.
