The given diagram demonstrates the steps involved in the process of recycling aluminium cans.
Overall, this is a man-made linear process, which consists of 11 stages and takes six weeks to complete. The sequence starts with the transportation of the used aluminium, is followed by cleaning with chemicals, and ends with the production of new cans.
Regarding the first six steps, the waste metal scraps are transported by a garbage truck and deposited at the recycling factory. Here, they undergo the initial cleaning step, including being sprayed with water, before being crushed by a machine. In the following step, the aluminium is processed, after which chemicals are applied to remove unwanted ink.
The subsequent steps produce new cans made from aluminium. The resulting aluminium then undergoes a heating process, allowing it to be moulded into the desired shape. After that, the weights of the shaped cans are measured, before the label is inserted by rolling. Finally, new cans are produced.
