PROBLEM TO BE SOLVED: To provide a waste disposal method and waste disposal facilities capable of producing slag as a by-product which can be utilized as the concrete aggregate in the waste disposal method and waste disposal facilities which partially oxidize/liquefy and melt wastes. SOLUTION: In the waste disposal method using waste disposal facilities having a high temperature reaction column 5 for partially oxidizing/liquefying and melting wastes and/or a carbonization product of the wastes, a melt heating/heat retaining furnace 16 for heating and heat retaining a melt formed in the high temperature reaction tower 5 which is connected to the side wall of the high temperature reaction tower 5, and a melt discharge opening 14H attached to the melt heating/heat retaining furnace 16, an oxygen-containing gas is supplied to the melt heating/heat retaining furnace 16, and the oxygen concentration in the gas in the neighborhood of the surface of the melt opposite the oxygen-containing gas feed opening within the melt heating/heat retaining furnace 16 is preferably rendered >=0.1 vol.%, and the waste disposal facilities to be suitably used in this waste disposal method are disclosed.
