Sample answer 1 :
The diagram depicts the process of recycling aluminum cans. Overall, this process involves multiple steps, including collection, transportation, processing materials, shaping and selling final products.
To begin with, used aluminum cans are collected in recycling bins before being transported to a recycling facility where they are cleaned thoroughly to remove any impurities, such as dirt, grease, and other contaminants. Next, the cleaned cans are sorted in order to ensure that the chosen cans are suitable for recycling and to separate them from other waste materials. Once sorted, the cans are shredded into smaller pieces and then crushed in a special machine to reduce their size and make them easier to handle.
After that, the resulting products are melted down at a high temperature, which turns them into a molten liquid. The liquid aluminum is then poured into molds to shape it into sheets. These thin sheets can be used to manufacture beverage cans, three-quarters of which can be recycled after use.

Sample answer 2 :
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.
