Metal wastes are generated in a number of industrial processes including foundry operations, metal surface cleaning and stripping, surface treatment, electro- and electroless plating, and coating operations. Disposal of metal wastes is increasingly subject to federal and state restrictions, making waste management more costly. As a result, there is heightened interest in preventing metal waste generation, in recycling the wastes once they are produced, and in developing treatment alternatives that reduce the amount of waste requiring disposal.
The California Department of Health Services, which is the California agency responsible for regulating the disposal of hazardous wastes, has an active program supporting the development of improved waste management practices, including waste minimization, among the state's industries. This symposium on metal waste management alternatives is one of DHS' efforts to encourage industry in developing strategies for reducing metal waste generation and to make this information available as widely as possible.
