Abstract
A recovery method of a compact disc includes the steps of: crushing a compact disc; b) placing the crushed compact disc into a stripping solution, so that the metallic layer is separated from the plastic base plates of the crushed compact disc; c) filtering the plastic base plates from the stripping solution; d) recovering the metal; and e) recovering the plastic base plates. Thus, the waste compact disc may be recovered and reused, thereby preventing incurring an environmental pollution.
