The aluminum industry in the United States in 2023 produced 860 thousand metric tons of aluminum from refined metal ore (primary production), at six smelters. In addition, US industry recycled 3.4 million tons of aluminum (so-called secondary production aluminum). [ 1 ]
The metal recycling industry encompasses a wide range of metals. The more frequently recycled metals are scrap steel, iron (ISS), lead, aluminum, copper, stainless steel, and zinc. Steel [10] is the most recycled due to its sustainable properties. There are two main categories of metals: ferrous and non-ferrous.

Goal 12, Responsible Consumption and Production, specifies 11 targets "to ensure sustainable consumption and production patterns". [31] The fifth target, Target 12.5, is defined as substantially reducing waste generation by 2030, indicated by the National Recycling Rate. In 2018, changes in the recycling industry have sparked a global "crisis".
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
Alcoa is well known for being one of the world's largest aluminum producers, not to mention the unofficial opener of every earnings season. However, like most materials companies, Alcoa has ...
Aluminium production became a source of concern due to its effect on the environment, and aluminium recycling gained ground. The metal became an exchange commodity in the 1970s. Production began to shift from developed countries to developing ones; by 2010, China had accumulated an especially large share in both production and consumption of ...
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
