<p>PROBLEM TO BE SOLVED: To achieve post utilization of thermoplastic resin as waste by a method wherein a bulk material of heat treated thermoplastic resin is crushed to a specific particle size, and the crushed small lump is used as aggregate. SOLUTION: Thermoplastic resin-made destruction rubbish of foamed styrol or the like is reduced in volume by heating treatment, and a bulk material is obtained. As a heating method for reducing the volume, for example, the thermoplastic resin-made waste is melted utilizing heat of water vapour. Further, when cooled after melting, the bulk material is obtained. Then, while the lump material is crushed to about 5 to 30mm with a crusher, the obtained small lump is used as aggregate A.</p> |
