A system and method for recycling a workpiece comprises an electrolytic etching assembly for etching a metal layer of the workpiece. The electrolytic etching assembly has an electroetching unit, a working stage, a power supply and an electrolyte source supply. The electroetching unit has an anode, a cathode next to the anode and an insulting covering, wherein the cathode and the anode are separated by the insulting covering which covers the anode. The working stage is provided for carrying the workpiece so as to allow the metal layer to face the anode and the cathode. The power supply has a positive electrode connected with the anode of the electroetching unit, and a negative electrode connected with the cathode. In addition, the electrolyte source supply is communicated with the insulting covering of the electroetching unit, and pours an electrolyte solution onto the anode and thereafter impinging upon the workpiece and passing through a passage defined by the workpiece and the anode.
