WASTE MINIMIZATION ASSESSMENT FOR A METAL PARTS COATING PLANT

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 hazardous 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). The WMAC team at University of Tennessee inspected a plant where automotive parts are coated with epoxy, vinyl, or polyestr powders; with liquid plastisol; or with paint. After the WMAC team analyzed five process lines (for applying coatings) and the reworking operation (where unacceptably finished parts are stripped), a report was prepared detailing their findings and recommendations. They found three waays to reduce the evapotration of methylethyl ketone (MEK), the largestsource of waste on the process lines: reduce the open susrface area of the MEK container, cool the MEK, or meter the MEK. They also found ways to reduce wastes from the rework process by installing controls, repairing defective drive components, or using alternative methods to remove defective coatings. The 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 documentd in a separate report of the same title from the authors.
