What are they?
Aluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull grey, depending on the surface roughness. Aluminum finds extensive use in air, road and sea transport; food and medicine; packaging; construction; electronics and electrical power transmission.
Why do they need to be sorted?
Aluminum is theoretically 100% recyclable without any loss of its natural qualities. Secondary aluminum is produced in a wide range of formats and is employed in 80% of alloy injections. Another important use is an extrusion.
How is it recycled?
Aluminum recycling is the process by which scrap aluminum can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminum.
