PROBLEM TO BE SOLVED: To provide a treatment method and a treatment device of waste capable of solving a problem arising from the control of a filling time into a furnace and the upper end surface position of the waste. SOLUTION: A waste treatment furnace has a furnace body; a gas discharge port arranged at the upper part of the furnace body; a discharge port for molten slag and/or a molten metal arranged at the lower part of the furnace body; a waste charging port arranged between the discharge port for the molten slag and/or the molten metal and the gas discharge port; a furnace center lance arranged on the upper part of the furnace body along the furnace axis, for blowing combustion supporting gas downward into the furnace; one or more upper tuyeres arranged on the furnace wall between the waste charging port and the gas discharge port; and one or more tuyeres arranged on the furnace wall between the waste charging port and the discharge port for the molten slag and/or the molten metal. When raising the temperature of the waste treatment furnace, a charcoal material wherein the total concentration of included halogen is 0.1 mass% or less is charged into the waste treatment furnace, and the height level of the upper end surface of the charged material inside the waste treatment furnace is adjusted from a temperature raising stage.
