Environmental Guidelines for Aluminum Manufacturing
production of secondary aluminum include particulates, pot lining refractory material, and salt slag. Particulate emissions, possibly containing heavy metals, are also associated with secondary aluminum production. Pollution Prevention and Control Pollution prevention is always preferred to the use of endofpipe pollution control facilities.
