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 That document has been superseded by the Facility Pollution Prevention Guide (EPA/600/R-92/088, May 1992).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 several varieties of electrical rotating devices. Metal stock is machined, cleaned, and surface-treated if required. Laminations, which are used in rotor, stator, and stepper assemblies, are manufactured in-house from strip stock. Rotors, stators, and steppers are manufactured through a series of operations and are then assembled into the finished devices. The team's report, detailing findings and recommendations, indicated that spent solutions from the four-stage aqueous cleaner are the waste streams generated in the greatest quantity and that significant cost savings could be achieved by discontinuing the use of Freon vapor degreasing for precision parts cleaning.
