Jendrucko, R. J., T. M. Thomas, AND G. P. Looby. POLLUTION PREVENTION ASSESSMENT FOR A MANUFACTURER OF COMBUSTION ENGINE PISTON RINGS (EPA/600/S-95/015). U.S. Environmental Protection Agency, Washington, D.C., 1995.
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. 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 That document has been superseded by the Facility Pollution Prevention (EPA/600/R-92/088, May 1992). The WMAC team at the University of Tennessee performed an assessment at a plant that manufactures piston rings. Steel and iron rings are machined, chrome-plated or coated, machined again, cleaned, and shipped to customers. The assessment team's report, detailing findings and recommendations, indicated that wastewater and wastewater treatment sludge are the waste streams generated in greatest quantity and that the greatest cost savings could be achieved by modifying the method of masking the rings prior to chrome plating.
