Waste Minimization Assessment for a Manufacturer of Cutting and Welding Equipment.

摘要

The WMAC team at Colorado State University performed an assessment at a plant that produces custom-built cutting and welding equipment. Components are fabricated from steel and other raw materials that are cleaned, machined, welded, and painted. Machines are then assembled, tested, and calibrated. The hazardous wastes generated by the plant include tramp oil, spent cutting fluid, spent lacquer thinner, and chromium-contaminated paint dust and filters. The team's report, detailing findings and recommendations, indicated that the plant could achieve the greatest dollar savings by replacing chromium-containing solvent-based paints with chromium-free water-based paints.
