Abstract: Disclosed is an organic material disposal method comprising a step for thermally decomposing a raw organic material and a gas treatment step for treating a gas generated in the preceding step, wherein the thermal decomposition step comprises a substep of decomposing the raw organic material into a carbide and a gaseous component, and the gas treatment step comprises the following substeps (1) to (5): (1) catalytically oxidizing the gaseous component produced in the thermal decomposition step; (2) neutralizing/washing the oxidized gas; (3) subjecting a waste water produced in the neutralization/washing step to the solid-liquid separation; (4) further thermally decomposing a solid component separated in the solid-liquid separation step together with the raw organic material in the thermal decomposition step; and (5) re-using a liquid component separated in the solid-liquid separation step in the solid-liquid separation step and/or the neutralization/washing step.
