Description:
The U.S.Environmental Protection Agency (EPA) has funded a pilot project to assist small and medium-size manufacturers who want to minimize their generation of waste but who lack the expertise to do so. In an effort to assist these manufacturers Waste Minimization Assessment Centers (WMACs) were established at selected universities and procedures were adapted from the EPA Waste Minimization Opportunity Assessment Manual (EPA/625/7-88/003, July 1988). That document has been superseded by the Facility Pollution Prevention Guide (EPA/600/R-92/088, May 1992). The WMAC team at the University of Tennessee performed an assessment at a plant that manufactures ceramic mountings for electronic circuit components. Several types of mountings, varying in size and number of ceramic layers and connectors, are manufactured by the plant. Ceramic sheets are manufactured onsite and coated with tungsten paste. The sheets are scored or cut, cured, inspected, and nickel-plated, gold-plated, and brazed as required. The team's report, detailing findings and recommendations, indicated that the waste stream generated in the greatest quantity is wastewater from the plating lines and that significant cost savings could be achieved by purifying and reusing the effluent from the onsite wastewater treatment plant.
