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 bin who lack the expertise to do so. aste Minimization Assessment Centers (WMACs) were established at selected universities and procedures were adapted from the EPA Wart Minimization Opportunity Assessment Manual (EPA/625/7-88/003, July 1988). The WMAC tea at Colorado State University performed an assessment at a plant manufacturing machine parts -- approximately 500,000 units/yr, This facility performs precision machine-shop work on a job shop basis. he process begins with cutting the stock to size, machining and hand deburring the parts. ext, the parts are machine deburred in a large tumbler washed, degreased, shipped offsite for chromating, and returned, assembled, inspected packaged, and shipped. he team's report, detailing findings and recommendations indicated that the majority of waste was generated by the deburrer rinse but that the greatest savings could be obtained by replacing the cutting fluid concentrate, thereby eliminating the need for degreasing with 1,1,1-trichloroethane. his Research Brief was developed by the principal investigators and EPA's Risk Reduction Engineering 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.
