The diagram describes the recycling process of aluminium cans.
Overall, the process contains seven individual steps, which begins from the collection of cans to the reuse of cans.
First of all, the used cans are collected from disposal bins and transported to the factory by trucks. In the factory, these cans are cleaned and sorted initially; then shred and compressed in a special machine. Subsequently, in order to produce new aluminium materials, compressed cans are heated to a desired temperature until they melt and turn into liquid form. After this, the liquid aluminium is set free in the room temperature to transform itself to solid form. This solid aluminium is rolled flat at a thickness of 2.55 mm to 6 mm depending on it’s use. Now the aluminium is ready to be recycled into new cans. The recycled cans are then sent to factories such as soft drink factories, where it is filled and sold to the public.
The used cans can be recycled again. In the UK, around 74% of all cans that are sold are recycled.
