|a Recycling of useful materials such as metals and plastics are evaluated important from the viewpoint of resource conservation and environmental protection. In this respect, the application of pulsed power technology to the recycling field has attracted considerable attention. We used a compact disc-read only memory (CD-ROM) as a separation processing target in this study. A magnetic pulse compression pulsed power generator (MPC-PPG) was designed and constructed to provide a positive pulse voltage. By applying an electric discharge, the protective layer containing the metal layer was separated from the plastic substrate in the atmospheric air. Here, to clarify the mechanism of the metal separation, shock waves and their induced fluid flow generation and propagation were observed by schlieren and shadowgraph visualization methods. Initially, the Mach number of the shock wave was 5.6, soon afterward the shock wave velocity decreased gradually. The fragments of the metal and the protective layers were removed from the plastic substrate with the shock wave propagation. The proposed method and process is applicable to the recycling of electronic wastes on an industrial scale for efficient recovery of valuable materials
