Aluminum producers and recyclers in the aluminum industry work with individuals, businesses, and communities to enable both curbside and industrial recycling programs.

Aluminium recycling Wikipedia

Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply remelting the metal, which is far less expensive and energyintensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
