Abstract

A two step electrochemical delacquering and de-tinning process has been developed to recycle post consumer tin cans. Lacquer coatings are removed using cathodic polarization in a basic electrolyte. The action of hydrogen evolution together with the wetting action of the electrolyte facilitates lacquer removal. Tin dissolution does not occur since the fragments are cathodically protected. This prevents the organic material waste from being contaminated with metal ions. The tin is selectively removed in the second bath by anodically dissolving the tin in a basic solution. Since the tin is selectively removed, the fate of other potentially hazardous materials such as chrome, nickel, copper and lead can be controlled. Tin that is removed from the tin can fragments is plated onto a cathode, reducing any sludge that may be formed from tin oxide precipitation.
