NKK Electric-resistance Furnace for Residues from Municipal Solid Waste Incineration Plants

摘要

Landfill capacity is decreasing rapidly. The remaining landfill sites in Japan will be used up in about 8 years because of ever-increasing residues from municipal solid waste (MSW). New sites difficult to fine and create for the residues to be landfilled. In addition, the residues contain toxic heavy metals as well as dioxins and requires special detoxification treatment before disposal. The vitrification pro- cess can solve these problems by 1) reducing volume of residues and recycling the vitrified products, which can help to reduce the landfill shortage problem, and 2) detoxifying the residues.
