Overall, the assessment identified 18 pollution prevention pollution opportunities at this facility. Recommendations for pollution prevention include replacing the solvent degreaser with an alkaline cleaner, improving process solution monitoring, and capturing and returning 100 percent of chromium dragout to the process solution. This facility is an electroplater that performs zinc, nickel, brass, and chrome plating. Seventy percent of production is comprised of brass articles. Approximately 15 m2 of metal surface is finished per day.
Parts are first polished.
Polishing paste is applied to stationary belt sanders to provide the necessary abrasion. The parts are then polished with the sanders. Dust generated by the polishing process is collected by vacuums connected to each machine. EPA is sponsored by the U.S. Agency for International Development. The assessment identified 18 pollution prevention opportunities that could address the problems identified above, with significant environmental and economic benefits to the facility.
