ENVIRONMENTAL RESEARCH BRIEF: WASTE REDUCTION ACTIVITIES AND OPTIONS FOR A MANUFACTURER OF ELECTROPLATING CHEMICAL PRODUCTS.
Ulbrecht, A. AND D. J. Watts. ENVIRONMENTAL RESEARCH BRIEF: WASTE REDUCTION ACTIVITIES AND OPTIONS FOR A MANUFACTURER OF ELECTROPLATING CHEMICAL PRODUCTS. U.S. Environmental Protection Agency, Washington, DC, EPA/600/S-92/059 (NTIS 93-126258), 1992.
The U.S. Environmental Protection Agency (EPA) funded a project with the New Jersey Department of Environmental Protection and Energy (NJDEPE) to assist in conducting waste minimization assessments at thirty small- to medium-sized businesses in the state of New Jersey. One of the sites selected was facility that produces chemicals for use in electroplating baths. The process formulates and blends concentrates of metal salts and additives which are used in electroplating and other metal finishing operations. The resulting solutions are clarified and tested for quality and consistency. Site visit was made in 1990 during which several opportunities for waste minimization were identified. Options identified include a spill prevention plan, expanded-use of ion exchange, and electrowinning to recover metal from concentrated waste streams. Implementation of the identified waste minimization opportunities was not part of the program. Percent waste reduction, net annual savings, implementation costs and payback periods were estimated.
