Abstract

Abstract: In this paper, the recovery of reflecting layer metal, recording layer dye, and the base polycarbonate of compact disks (CDs) were studied via chemical dissolving. The solvent concentration, temperature, and stirring were found important factors in recovery. The reflecting layer metal was collected in forms of AlCl3 or AgCl. The recording layer dye was extracted using alcohol. Besides, back-deposit method was also found effective in the recovery of reflecting layer metal.

Key words: discard CD-R, recycling, recording layer dye, polycarbonate
