The production and consumption of so many optical discs is bound to generate a large number of obsolete optical discs every year. More than 99.97% of the base material of waste CD discs and defective discs eliminated from the manufacturing process is polycarbonate (PC). Polycarbonate is an engineering plastic with high toughness and high transparency. It has excellent properties such as heat resistance, impact resistance and stability. It is widely used in optics, electronics, machinery, automobiles, medical treatment, building materials and other fields. It has high recycling value.

The core of recycling waste optical discs is to remove the metal coating on the surface of the optical discs to obtain polycarbonate substrates. The current treatment methods are mainly divided into dry method and wet method. The wet method is a chemical method, which uses an appropriate solvent such as chloroform, methanesulfonic acid or alkali to remove the surface coating of the disc. The product quality of this kind of process is good, but it will bring the secondary pollution problem of cleaning wastewater treatment discharge. The dry method is a physical method. At present, a cutter is mainly used to remove the surface layer of the optical disc.
