PROBLEM TO BE SOLVED: To obtain a thermoplastic resin molding being advantageous in respect that the constituent aluminum hydroxide does not cause foaming during mixing and molding, reduced in the CO concentration of a waste gas produced when incinerated, and having improved impact strength by mixing a thermoplastic resin with aluminum hydroxide and a moisture-absorbing agent and molding the mixture. SOLUTION: A mixture obtained by kneading a thermoplastic resin with 0.1-5 wt.%, desirably, 0.5-2 wt.% moisture-absorbing agent having a content of 30μm or larger particles of 1 wt.% or above and a moisture-absorbing rate of at least 3 wt.%/hr at 130-200 deg.C for 5-30 min is cut and cooled to obtain pellets. The pellets are mixed with 0.1-15 wt.%, desirably, 1-10 wt.% aluminum hydroxide having a 90% cumulative diameter of at most 30μm, or desirably, at most 10μm, and the mixture is molded to obtain a molding. When the molding is incinerated together with miscellaneous refuses, the aluminum hydroxide releases its water of crystallization under high-temperature conditions in the incinerator to form high-specific-surface area active alumina which inhibits dioxins from escaping from the incinerator.
