Waste compact disks are identified to be hazardous waste in Taiwan. If we recycle the waste compact disks, their impact will be reduced Up to now commercial technology can used to recycle single layer CD only. Although many researches have interested in the treatment of waste DVD, there is no any appropriate technology to be addressed yet. Our team has accomplished the method to recycle all forms of Compact Disks through our efforts for ten months. The waste compact disks recycle method is follow to the principle of cleaner production. The method does not use toxic raw materials and discharge hazardous materials. The steps are shred the waste Compact Disks, soak them into NaCl,H2SO,liquid alkali reactor and aerate to approximately strip off the printing layer, the reflective layer and the dye layer. After clearing them completely in cleaning tank, waste CD were dehydrated and air-dried to be polycarbonate plastics. The of recycled rate polycarbonate plastics is 95% and the physicochemical properties is nearly the test norms for DVD gradation. It is perceived that the method to recycle compact disks influenced on physicochemical properties of polycarbonate plastics is low
Now, pilot planet operating step is completed. In the future, our team will consider to establish a factory or to sell the technology. We hope the producing procedure of the reclaiming waste Compact Disks is conforms to the principle of cleaner production. We also like to establish the industry in harmony with our environment.
