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. These deposits cannot be removed by scraping or wiping. To alleviate this problem, the facility can take several steps. Reducing the amount of polishing compounds used will reduce the amount of debris.
