摘要： PROBLEM TO BE SOLVED: To provide an effectively treating method of solid-state waste for immobilizing a metal in solid-state waste with a complex forming compound such as a metal capturing agent so that labor, time and expenses for hardening the treated waste with cement are saved and there is no fear that the treated waste becomes fragile and fragmented to easily elute the metal even when exposed under severe natural environment. SOLUTION: This treating method comprises adding the compound having complex forming capacity with the metal to the solid-state waste and kneading them in the presence of a calcium compound and an aluminum compound of 5 wt.% or more based on the weight of the calcium compound to immobilize the metal in the solid-state waste.
