WE can make Steel and Aluminum but under Obama's policies American steel mill started laying off workers in 2015 and continued until early 2017, we have the mills but dumped the workers from Obama's trade deals, refusal to add import tariffs and his EPA "green" regulations.
Because making one to of Aluminum generates 2 tons of waste , much of which is processed into other items but one by product is called Red Mud which is caustic,. The U.S. EPA in 2014 did not approve any secondary use of the waste. The radioactivity content is only one of several concerns that pose a risk to the environment, as red muds also have a high salinity and pH. In some red mud samples, the EPA has identified elevated arsenic and chromium concentrations; in some cases, arsenic levels were as high as 16,000 parts per billion , and chromium up to 374,000 parts per billion. In the United States, wastes are required by the EPA to be disposed in large impoundments that are lined with clay and /or synthetic liners at a cost to manufacturers of approximately 18,000 dollar per ton for transport, containment, site monitoring and testing of the soil and air around the sites. The Bauxite mining is even more EPA restricted since 2010.
You need to free up and restore the ability to produce and compete before you start a needed trade war.
