Abstract:
Waste incineration has nowadays become more common, so the new kind of slags and ashes are to be managed in Finland. Treatment and disposal of these residues affect significantly the operating costs of a waste incineration plant, and when disposed without utilisation the slags and ashes will also burden landfills. Meanwhile there are also a number of national and EU-level development initiatives ongoing in Finland to enhance the reuse of waste materials. The reuse of bottom ash requires suitable upgrading processes, as it is not as such, without upgrading suitable for material reuse. The aim of this ongoing co-operation project of VTT and GTK is to process a novel reuse material suitable for earth construction purposes from MSWI bottom ash, and to develop innovative waste material upgrading technologies based on current ore enrichment processes. The development work has shown some promising results, most of metal elements can be enriched by using mineral processing technology.
