In order to obtain fundamental data for thermal decomposition process of waste containing water, a disposal diaper with water-absorbent polymer was decomposed in an image furnace. Mass reduction during thermal decomposition was measured by an electric micro-balance. The gas components produced by thermal decomposition were analyzed with FT-IR gas analyzer (MEXA-4000FT, Horiba Ltd.). The oxygen concentration in the furnace was set to 0% or 21%, and the water which was contained in a diaper was changed from 0 to 30 times of the initial mass of sample. It was found that thermal decomposition period became long with increasing water. In the 0% oxygen concentration, peak emission of HC was increased with increasing the water content. However, peak emission of CO was constant regardless of water content.
