Write at least 150 words.
The diagram illustrates how aluminium cans are recycled. First, the cans need to be taken to special collection centres instead of being thrown away with the normal refuse. The cans are collected from here and taken to a factory where they are first sorted and then cleaned. Next, the cans are shredded and crushed in a special machine.
The metal is then heated to a high enough temperature to allow the aluminium to melt. It is then rolled out flat to a thickness of between 2.5mm and 6 mm, depending on what it is going to be used for. The aluminium is now ready to be recycled into new packaging, such as drink containers. Finally, the new cans are delivered to a soft drinks factory where they are filled. The cans can now be sold to the public and reused. In the UK, 74 per cent of all aluminium cans that are sold are recycled.
