<p>A method of recycling a laminate shaped product, including the steps of: breaking a shaped product having a laminate structure including at least one layer of aliphatic polyester resin in addition to a principal resin layer, storing resultant broken pieces in a moisturizing environment to adjust a moisture content of the aliphatic polyester resin (layer) to at least 0.5 wt.%, and then washing the broken pieces with alkaline water to remove the aliphatic polyester resin layer, thereby recovering the principal resin. As a result, it becomes possible to shorten an induction period in the alkaline water washing step that is a principal process step, thereby rationalizing the entire process.</p> |
