Assessment Topic

Two hundred seventy-one plants employing approximately 31, 200 people comprise this category. Of the 271 plants, 59 discharge directly to rivers, lakes, or streams; 72 discharge to publicly owned treatment works (POTW); and 140 do not discharge process wastewater. Most of the zero discharge plants employ a combination of forming and ancillary operations which do not generate process wastewater. Aluminum forming processes are those manufacturing operations in which aluminum or aluminum alloys are shaped into semi-finished or mill products by hot and cold working. These operations, called core operations, include rolling, extruding, forging, and drawing of aluminum. Associated processes, called ancillary operations, are practiced to achieve desired aluminum product characteristics or finishes, and include the casting of aluminum alloys for subsequent forming, heat treatment, and all suface treatment operations performed as an integral part of aluminum forming (called cleaning or etching).
