How is Aluminum Recycled?
Abridged and adapted from a Norsk Hydro video voiceover
TEXT
1 - Aluminum recycling is a crucial component in the pursuit of a perfect circular flow economy.
2 - It enables the transformation of used beverage cans into new beverage cans, and discarded window frames into fresh window frames.
3 - Each year, approximately 36 000 tons of old aluminum window frames contribute to the growing mountain of discarded material.
4 - This waste arises not only from building renovations but also from the increased use of lightweight aluminum in the automotive and electronics industries.
5 - Consequently, there is an urgent need to find effective methods to recycle aluminum efficiently.
6 - The recycling process begins with the use of shears and a conventional shredder to cut up the frames.
7 - Magnetic separators and an eddy current separator are then employed to extract metal screws and hinges as well as any rubber, wood and plastic components.
8 - The resulting waste contains old aluminum window handles and rivets that are unsuitable for window frame alloys.
9 - To address this issue, those unsuitable materials are sorted out by a special x-ray machine.
10 - A second phase involves re-shredding and sieving the material, optimizing it for the subsequent x-ray machine.
11 - The coarse aluminum parts are meticulously cut into chips measuring four to six centimeters using steel blades that are specially hardened to withstand aluminum’s abrasive nature.
12 - The two shredders have a combined capacity of over 100 tons of aluminum chips per day.
13 - Subsequenly, a screening unit filters out smaller particles, resulting in a homogeneous material flow that facilitates the detection of individual fragments in the subsequent x-ray machine.
14 - The individual parts are examined by powerful x-ray sources with an energy of 160 kiloelectron volts.
15 - To ensure the protection of workers from radiation exposure, the unit is covered with a robust lead shield.
16 - The aluminum chips are spread evenly on a wide conveyor belt with x-ray lamps inspecting them from above.
17 - Simultaneously, an x-ray detector beneath the belt measures the incoming radiation.
18 - This data is used by a computer to differentiate between various alloys and operate a strip fitted with nearly 400 pressurized air jets.
19 - These air jets blow off the unsuitable material at a rate of 100 parts per second.
20 - The grounbreaking technology enables the separation of unsuitable heavy metal alloys which typically constitute about two to four percent of the material, redirecting them to other material cycles.
21 - The majority of the recycled material consists of highly valuable aluminum alloys such as 6060 and 6063 which have been extensively used for window frame production for several decades.
22 - The innovative shredding and sorting technologies allow for the annual recycling of 30 000 tons of this high-quality material which is then easily transported to customers like the Hydro Aluminum Company.
23 - Hydro Aluminum produces approximately 3 000 tons of aluminum billets per year.
24 - These billets serve as a vital primary material for pressing plants where they are used to manufacture aluminum profiles including those for window frames.
25 - The recycled material in the form of aluminum billets is melted down at Hydro’s plant in cockpits through a specialized process.
26 - Extrusion billets measuring approximately 25 centimeters in length are produced.
27 - These billets composed of recycled aluminum and with minimal primary aluminum content are crucial for reducing the environmental impact of the entire production process.
