Disposal, uses and treatments of combustion ashes: a review

L. Reijnders

Resources, Conservation & Recycling, 2005, vol. 43, issue 3, 313-336

Abstract: Ashes resulting from the combustion of fuels can contain mobile compounds that may give rise to significant pollution on disposal or during use. Source reduction has limited potential in reducing such pollution. Thus for polluting elements immobilization and forced extraction may be considered and regarding organic pollutants: destruction. Thermal destruction of hazardous organics in the presence of a catalyst is practised. In case of immobilization permanent sequestration of once mobile elements in quartz-type silica lattices is an attractive option to prevent future pollution by such compounds. So far full sequestration of hazardous compounds in quartz-type silica lattices has not been demonstrated. Partial sequestration has been shown and is widely applied.
