How are Aluminum Cans Recycled?

Step 1: Collection * Aluminum cans are collected from recycling bins, landfills, and curbside pickup programs.

Step 2: Sorting and Baling * Cans are sorted by type (e.g., soda, beer) and then compressed into bales for efficient transportation.

Step 3: Shredding * Bales of cans are shredded into small pieces to facilitate processing.

Step 4: Demagnetization * Shredded cans are passed through a magnetic separator to remove any steel or other ferrous materials.

Step 5: Cleaning * The remaining aluminum fragments are washed to remove dirt, paint, and other contaminants.

Step 6: Melting * Cleaned aluminum is melted in a furnace at high temperatures to form a molten alloy.

Step 7: Casting * Molten aluminum is poured into molds to create new aluminum products, such as sheets, bars, and ingots.

Step 8: Extrusion or Rolling * Cast aluminum is either extruded (pushed through a die) or rolled to desired shapes and sizes for various applications.

Step 9: Fabrication * Extruded or rolled aluminum is used to manufacture new products, including aluminum cans, automotive parts, and construction materials.
