Leaching behaviour of a glassy slag and derived glass-ceramics from arc-plasma vitrification of hospital wastes

The arc-plasma vitrification of a hospital wastes containing metals and inorganic oxides yields to a leach-resistant glassy or vitreous slag, which can be environmentally safe for landfill disposal or could be transformed in glass-ceramic tiles with physical and mechanical properties similar to thos...
