Sustainability – Recycling | Aluminum Association
Aluminum production in the U.S. is increasingly a story of scrap recovery and recycling. While primary aluminum production remains a vital part of the American aluminum supply chain, more than 80% of U.S. production today is in making recycled (or secondary) aluminum. This compares to 20% to 30% recycled production in the 1980s.
