Abstract: [Problem] To provide a method for producing useful substances, which converts organic waste containing heavy metals into harmless substances such as fertilizers and soil conditioners by carbonizing organic matter while detoxifying heavy metals.
[Solution] The present invention is a method for producing a useful material, said method comprising treating an organic waste in which heavy metals are mixed to produce a carbonized material containing weighed material. The organic waste in which the heavy metals are mixed is treated by dry carbonization of an organic waste to which a Ca component starting material and a SiO2 component starting material, which are topalmorite starting materials, are added in amounts sufficient to contain the mixed heavy metals in topalmorite crystals; a charcoal-forming step of dry carbonizing the waste, carbonizing the organic waste to form a carbide; the carbide formed in this carbide forming step and the topamolite raw material are charged into a reaction vessel while maintaining the high temperature state in the previous step, and slowly cooled in the presence of water with stirring to form the organic material; a heavy metal confinement step of forming a topamolite crystal mineral in which heavy metals mixed in the organic waste are confined, and forming a slurry in which the carbide and the topamolite crystal mineral are dispersed; and drying or dehydrating the slurry formed in the previous step to produce a useful substance containing a carbide containing the topamolite crystal mineral.
