Description:
For metal finishing operations to remain competitive and in compliance with environmental requirements, companies must focus their efforts on pollution prevention to reduce waste generation and disposal costs, limit liability and restore maximum profits. By applying the pollution prevention concept, metal finishers can reduce the generation of metal-bearing wastes at the source. When waste cannot be reduced in the process, the preferred alternative is the recovery/recycle of metals and the maintenance of process solutions used. Metals recovery/recycle is an important aspect to consider when the risk to human health and ecological consequences is involved. To maximize pollution prevention, water use must be minimized, metals must be recycled "in process" or recovered, and contaminants must be removed from the process bath to extend bath life. This review covers source reduction, current and competing technologies, bath life extension and the most efficient pollution prevention measures for nickel electroplating processes.
