PROBLEM TO BE SOLVED: To provide a method for simple, easy, and efficient combustion of plastic by using an existing combustor, and the like. SOLUTION: As a medium for carrying plastics, 1.0-5.0 wt.% of a total air amount to be blown into the combustion furnace is blown together with plastics from a nozzle into the combustion furnace, and 10-30 wt.% of the total air amount is directly blown into a zone for thermal decomposition of plastics, and the air in the furnace and the plastic thermal-decomposition gas are diffusively mixed with each other.
