The flowchart illustrates the recycling process of aluminium cans after being used.

Overall, the process includes multiple stages, starting from the collection of aluminium cans from members of the public, through various steps involving specialized equipment, and ending with the use of cans made from recycled aluminium.

Looking at the first stage, aluminium cans are gathered up at some certain collection centres, in which people can deposit used cans in recycling bins. After that, they are taken to the recycling plant for cleaning, sorting, shredding and compression to make blocks of aluminium. These are then loaded by manually into an industrial furnace to melt the metal. In the next step, the molten aluminium is then poured into a rolling machine which produces aluminium sheets to a thickness of 2.5 mm to 6 mm. These sheets are used for various purposes including the production of cans for the soft drink industry. Subsequently, the recycled aluminium cans are reused by being sold at retail establishments. In the UK, about three-quarters of all sold cans are later recycled.

Sample answer 2

The flowchart shows how aluminium cans are recycled. In general, the recycling process has several stages from the collection of used cans to the reuse of recycled aluminium cans. 

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 until they form solid blocks. These blocks of metal are then heated to a high enough temperature to allow the aluminium to melt. It is then rolled out flat to a thickness of between 2.5 mm and 6 mm, depending on what it is going to be used for. The aluminium is now ready to be recycled into new packagings, such as drink containers. Finally, the new cans are delivered to a soft drink factory where they are filled. The cans now can be sold to the public and reused. In the UK, 74% of all aluminium cans sold are recycled.
