Pollution prevention assessment for a printed circuit board plant

Description: The US 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. The WMAC team at Colorado State University performed an assessment at a plant that manufacturers printed circuit boards. Templates for the circuit design are generated from customer-supplied circuit information. Copper/epoxy laminates and copper foil are cut into blank boards and layers. Circuit patterns are generated through a series of photolithographic and plating processes. The team`s report, detailing findings and recommendations, indicated that the onsite ion-exchange treatment of metal-containing rinse water generates regenerant solutions that could be further treated by electrowinning to recover metals and to achieve significant cost savings. This Research Brief was developed by the principal investigators and EPA`s National Risk Management Research Laboratory, Cincinnati, OH, to announce key findings of an ongoing research project that is fully documented in a separate report of the same title available from University City Science Center.

Environmental research brief: Pollution prevention assessment for a manufacturer of metal fasteners

Description: The US 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 That document has been superseded by the Facility Pollution Prevention Guide (EPA/600/R-92/088, May 1992).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 various types of metal fasteners for automobiles, furniture, and appliances. Products are manufactured from steel, brass, copper, and aluminum wire and rod stock in two production lines-large part production and small part production. In large part production, header machines press wire stock into specific product shapes which are washed, machined, and in some cases heat-treated and polished. Small parts are manufactured from wire and rod stock in a series of machining operations, then washed, heat treated and polished, before shipment to an outside firm for surface finishing. The team`s report, detailing findings and recommendations indicated that a large amount of plant oil waste is shipped off-site for fuels blending and a significant quantity of oily sludge waste is shipped offsite for disposal as non-hazardous waste. Large cost savings can be achieved by the plant through the use of alternative methods of removing metal chips from parts, thereby reducing intermediate washings.
