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. aste 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). he WMAC team at Colorado State University performed an assessment at a plant manufacturing finished metal components -- approximately 260,000 sq ft/yr, Customer-specified coatings and surface treatments are applied to prefabricated aluminum and stainless steel parts. Aluminum parts may be finished by hard-coat or soft-coat anodizing, and chromate conversion coating. tainless steel parts are finished by surface passivation. arts are also processed for surface Inspection using a fluorescent dye. and ultraviolet light. he team's report, detailing findings and recommendations, indicated that most waste was generated in the aluminum anodizing process, and that the greatest savings could be obtained by using hot deionized water instead of nickel acetate solution to seal pores in the aluminum oxide coating applied by anodizing. 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.
