The diagram shows the process of recycling aluminium cans. The process is a cycle and has several stages, from throwing away used cans to using new cans again.
Overall, the used cans are collected, cleaned and melted, and then they are made into new cans. This process happens again and again, and in the UK, 74% of aluminium cans are recycled.
First, people put their used aluminium cans into special recycling bins which are only for aluminium cans. Then, a truck comes to collect the cans from the bins and takes them to a recycling factory.
At the factory, the cans are cleaned, sorted, shredded and compressed by a machine. After that, they are heated and melted into liquid aluminium. The melted metal is then rolled into thin sheets, which are between 2.5mm and 6mm thick. These sheets are used to make new aluminium cans in the recycling stage. Finally, the new cans are filled with drinks and sold to people again, so they can be reused, and the whole process starts again.
