Waste Minimization Assessment for a Manufacturer of Water Analysis Instrumentation.

摘要

The U.S. Environmental Protection Agency (EPA) has funded a pilot project to assist small-and medium-sized 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 (PB92-216985, July 1988). The WMAC team at Colorado State University performed an assessment at a plant manufacturing instruments for water analysis -- approximately 50,000 units/yr. Primary operations include production of cabinets and assembly of instruments. The team's report, detailing findings and recommendations, indicated that most waste is generated as spent reagents and rinse water from metal surface finishing, but greatest savings could be obtained by filtering and pasteurizing metal cutting fluid for recycle and separating its organic and aqueous phases when disposal becomes necessary.
