PROBLEM TO BE SOLVED: To provide a waste disposal method solving a delay in the measurement of the composition of waste, estimating the composition and the lower calorific value of the charged waste from the gas composition obtained by the gasification of the waste and the composition of recovered matter and permitting the smoother treatment than conventionally by using the estimated value. SOLUTION: In a waste disposal method pyrolyzing, gasifying and melting waste to recover even a gas in addition to a metal and slag, the component element of the recovered gas is measured, and the composition of the charged waste is set by using the measured value, the quantity of recovered gas, the quantity of charged waste and the component and charge quantity of other charged matter to find the lower calorific value of the waste from the composition. In this case, respective 3 to 24-hour moving averages are desirably used for the measured value, the quantity of recovered gas and the quantity of charged waste.
