Description:
This guide provides an overview of the major waste generating process of metal casting and heat treating operations and presents options for reducing this waste through source reduction and recycling. ost waste generated by the metal casting, or foundry, industry is from melting operations, metal pouring, and disposal of spent molding materials. ost waste generated by the heat treating industry is from spent baths (e.g. cyanide solutions), spent quenchants, wastewater from parts cleaning, spent abrasive media, refractory material, and masking processes. o help companies in the metal casting and heat treating industry determine waste reduction opportunities, the guide provides a set of worksheets which take the user step by step through an analysis of the on-site waste generating operations and the possibilities for minimizing each waste. he guide is also intended to be instructive to consultants who serve the industry and government agencies who regulate it.
