The following diagram illustrates how aluminium cans are recycled. The process basically starts from properly eliminating the used cans to returning the recycled version of them to the market. To start with, after the used cans are disposed of in a specific type of trash bin, they are collected and transferred to the next station, where a special machine is required. At this stage, the collected metal containers are cleaned and sorted. Right after being categorised, they are to be shredded and crushed before being heated to melt. Subsequently, after melting into hot liquid, the metal is now flattened into a thickness of 2.5 to 6 mm, depending on different purposes. The roll of aluminium can now be turned into different types of containers, such as cans of drinks. These pieces of recycled packaging are then distributed to factories, such as a soft drink factory, where they are filled and sold. In the UK, 74% of the containers used in the market are recycled ones.
