<p>The synthetic resin having ester bond in the composition structure is subjected to the hydrolysis treatment to reclaim the raw material component before polymerization. Provided is a method for decomposing and reclaiming a synthetic resin having ester bond in the composition structure thereof, executing the hydrolysis treatment and the separation collection treatment in this order. The hydrolysis treatment is a treatment in which an article to be treated containing a synthetic resin to be decomposed and reclaimed is exposed to a water vapor atmosphere filled at or below the saturation water vapor pressure at a treatment temperature specified by the condition of treatment temperature of at or below the melting point of the synthetic resin, and the synthetic resin in the article to be treated is hydrolyzed by the water vapor generated at the treatment temperature, thus a decomposition product before polymerizing to the synthetic resin containing ester bond in the composition structure thereof is generated. The separation collection treatment is a treatment in which the decomposition product generated by the hydrolysis treatment is separated into liquid component and solid component to be collected individually.</p> |
