为了形成资源循环型社会，延长垃圾填埋场的使用寿命，城市垃圾焚烧炉残渣的熔融处理被认为是产品资源化回收的最佳方式。本文介绍了电弧熔炼系统的最新应用及其产品的利用情况。目前，五个工厂的运作情况令人满意，两个工厂正在建设中。这些设施的总容量相当于世界上最大的。这些工厂的炉渣和金属正在试验利用中。开发了从冷凝液中回收铅和锌的方法。对粉煤灰与底灰混合电弧熔炼工艺进行了验证，发现粉煤灰混合渣的力学性能和化学稳定性与底灰渣相当，均满足规范要求。
To form a resource recycling society and to extend the life of landfill sites, the melting process of municipal waste incinerator residue is estimated to be the best way of recycling products as resources. This paper presents a recent application of an arc melting system and utilization of its products. Five plants are now operating satisfactorily and two are under construction. Total capacity of these corresponds to the largest in the world. The slag and metal from these plants are under trial utilization. Pb and Zn recovery methods from the condensate have been developed. The arc melting process of fly ash mixed with bottom ash has been certified and the mechanical properties and chemical stability of fly ash mixed slag was found to be equivalent to bottom ash slag, both fulfilling the regulations.
