Method for recycling foamed polystyrol resin |
| abstract |
A method for recycling a foamed polystyrol resin, which comprises a volume reduction step (110) of reducing the volume of the foamed polystyrol resin, a resolution step (130) of dissolving the foamed polystyrol resin reduced in its volume in a solvent, and a step (160) of subjecting the dissolved foamed polystyrol resin to an extrusion process; and an apparatus for separating a polystyrene solution followed by recovering which is used in the step of subjecting the dissolved foamed polystyrol resin to an extrusion process. The above method allows the minimization of the difficulty of removal of a foreign matter and the decrease of molecular weight due to the heating during an extrusion step in a conventional heat melting method and the discharge of a vaporized solvent accompanied by a gas discharged in a volume reduction step and the loss of the solvent due to the discharge appearing in a conventional method of dissolution into a solvent. |
