The diagram illustrates the cyclical process by which aluminium cans are recycled in the UK.
Overall, aluminium can recycling is a multi-stage, closed-loop procedure that begins with consumer disposal of used cans and ends with new reusable cans being produced, with 74% of aluminium cans in the UK being recycled through this system.
To begin with, used aluminium cans are discarded by members of the public into dedicated recycling bins reserved for aluminium cans only. Next, these collected cans are picked up by specialised recycling collection trucks, which transport them to processing facilities. At the facilities, the cans first undergo four sequential treatments: they are cleaned thoroughly, sorted to separate suitable aluminium material, then shredded into smaller pieces, and finally compressed into compact blocks. Following this preparation, the compressed aluminium is heated and melted down into a raw molten state. This melted aluminium is then rolled into flat sheets with a thickness ranging from 2.5mm to 6mm. These rolled sheets are subsequently manufactured into new, empty aluminium cans, which are then ready to be filled with beverages and reused by consumers, completing the full recycling cycle.
