This paper describes efforts on waste minimization in the electroplating facility at Lawrence Livermore National Laboratory (LLNL). Issues that are covered include: elimination of cadmium plating, copper cyanide plating, hexavalent chromium plating and vapor degreasing, segregation of cyanide solutions, changing rinsing practices, recycling of rinse water, changing cleaning of aluminum parts and rejuvenation of gold plating solutions. Discussion is also presented on other issues currently being worked and these include: combining electroplating and physical vapor deposition, elimination of all cyanide plating processes, and recycling of electroless nickel and spent acid solutions.
