Waste Minimization Assessment for a Manufacturer of Pliers and Wrenches

摘要

The Waste Minimization Assessment Centers (WMACs) team at Colorado StateUniversity performed an assessment at a plant that manufactures pliers and wrenches. The products are manufactured from metal blanks that have been forged in another plant. The team's report, detailing findings and recommendations, indicated that the greatest quantity of waste in this plant came from the machining and plating operations. The greatest cost-saving opportunity recommended to the plant involved the replacement of 1,1,1-trichloroethane vapor degreasing with nonhazardous aqueous cleaning.
