Incineration is a major treatment process for municipal solid waste in Taiwan. It is estimated that over 1.5Mt of incinerator ash are produced annually. This study proposes using thermal plasma technology to treat incinerator ash. Sintered glass–ceramics were produced using quenched vitrified slag with colouring agents added. The experimental results showed that the major crystalline phases developed in the sintered glass–ceramics were gehlenite and wollastonite, but many other secondary phases also appeared depending on the colouring agents added. The physical/mechanical properties, chemical resistance and toxicity characteristic leaching procedure of the coloured glass–ceramics were satisfactory. The glass–ceramic products obtained from incinerator ash treated with thermal plasma technology have great potential for building applications. [Copyright &y& Elsevier]
