Provided is a method for producing a resin composition of polyvinyl chloride by removing lead in a resin molded article containing polyvinyl chloride as a main component and a lead-based stabilizer. The method includes: pulverizing the resin molded article to form a pulverized material; melting the pulverized material to obtain a melt; stirring the melt to which a solid adsorbent that adsorbs a lead ion is added to cause the lead ion in the melt to be absorbed onto the adsorbent; and separating the adsorbent having the adsorbed lead ion from the melt.

Provided is a method for recovering a plastic film from a laminate. The laminate includes a plastic film (I), an inorganic layer (II) including at least one selected from the group consisting of silicon oxide, aluminum, and aluminum oxide, and a cured resin layer (III). The cured resin layer (III) is a cured product of an epoxy resin composition containing an epoxy resin and an epoxy resin curing agent, which contains an amine-based curing agent. The method includes bringing the laminate into contact with an acid aqueous solution or an alkaline aqueous solution.
