Increasing amounts of municipal solid waste incineration (MSWI) residues are treated prior to landfilling or reuse. This study assesses the effectiveness of electric arc melting as a pretreatment technique for bottom ash vitrification, focusing on its impact on the mobility and fate of metals. Both bottom ash and the resulting slag were analyzed for total solids, fixed solids, particle density, specific surface area, particle size distribution, and metal content. A six-step sequential extraction procedure was employed to evaluate metal mobility, validated through availability and leaching tests, complemented by electron microscopy. The findings revealed that the electric vitrification process distinctly affected the availability of various metals, leading to their solidification, stabilization, or removal. Notably, the mobility of metals such as chromium, copper, zinc, lead, and calcium was significantly reduced in the slag. High concentrations of lead and zinc were likely removed from the ash through evaporation, while increases in aluminum, chromium, nickel, and cadmium content were attributed to the wear of furnace refractories. Overall, this research offers insights into the environmental implications of electric arc vitrification in treating MSWI residues.
