DEVELOPMENT OF NEW PRE-TREATMENT METHOD TO RECOVER RARE METALS IN MSW MELTING FURNACE FLY ASH: LEACHING CHARACTERISTICS OF RARE METAL ELEMENTS
© IWWG International Waste Working Group (10/2007)
Melting plants that treat municipal solid waste (MSW) and/or MSW incineration residues at high temperature (approx. 1,400°C) are preferred by many municipalities in Japan due to volume reduction of residues to landfill, decomposition of dioxins, reuse of molten slag, and reduction of hazardous metal leachability. The present number of operating plants is around 140, which corresponds to about 10% of the total incineration facilities (Jung et al., 2006). The primary products in melting plants are molten slag and fly ash, which are generated at about 0.5 million tons and 0.2 million tons per year, respectively.

Rio de Janeiro – Kyoto – Johannesburg – Stockholm - Basel – are focusing on the reduction of Greenhhouse gases. As a party to the UNFCCC South Africa has committed itself to report on and to reduce its production of greenhouse gases. In its Polokwane Declaration of 2001, South Africa committed itself to a waste free South Africa by 2022. South Africa has adopted the Waste Hierarchy as the foundation for waste management and is currently completing national legislation with this as a centre piece.
