The new technology uses electrolytic recovery with a PVC-based membrane which allows the passage of hydrogen and chloride ions but not the copper. The copper is transferred to the cathode and recovered as pure flakes. The quality of the printed circuit boards is improved. Disposal costs for copper are virtually eliminated. The etching solution is maintained at its optimum composition.
Copper is recovered in a high value form, and there are no hazardous chemicals to be handled.
