PROBLEM TO BE SOLVED: To effectively decompose dioxins in soil by reacting a halogenated organic compound with one or more of amino acid compounds selected from a group consisting of amino acids, polyamino acids, salts of amino acids and polyamino acids by heating. SOLUTION: When the soil around an incinerator, e.g. a garbage incinerator and the like is contaminated by halogenated organic compounds, e.g. polychlorodibenzo-p-dioxins, polychlorodibenzofuran and the like, the dioxins in soil should be decomposed. In such a case, the halogenated organic compound is decomposed and disposed by reaction the compound with one or more of amino acid compounds selected from group consisting of amino acids, polyamino acids, salts of amino acids and polyamino acids by heating. It is recommended that the amount of the amino of the amino acid compounds to be added is 0.1-10 wt.% to the materials to be disposed, e.g. soils and the like at the dried state, in view of the dioxin's decomposing efficiency and disposal cost.
