Recycling method of disc-shaped information recording medium |
| abstract |
(57) [Problem] To provide a method for recovering a polycarbonate resin having sufficient physical properties for a molding material from disc-shaped information recording medium waste. A method of separating and removing a thin film from a disc-shaped information recording medium having a laminated thin film provided on a polycarbonate resin substrate and recovering the polycarbonate resin, wherein the disc-shaped information recording medium is pulverized to remove a halogen-free solvent Alternatively, the laminated thin film is separated and removed by bringing it into contact with a supercritical medium, and then solid phase polymerization is carried out using the obtained polycarbonate resin powder as a raw material. A method for recycling disc-shaped information recording media using a polycarbonate resin of 00 or more. |
