The diagram illustrates the process of recycling aluminium cans. Overall, it is a circular process that begins with the disposal of used cans and ends with their reuse as new cans. According to the diagram, about 74% of aluminium cans are recycled in the UK.
First, people place their used aluminium cans into special recycling bins. After that, the cans are collected by a recycling truck and transported to a recycling centre. At the facility, the cans go through several preparation stages. They are cleaned to remove any remaining liquids or dirt. Next, they are sorted and then shredded into small pieces. After shredding, the pieces are compressed to make them easier to process.
In the next stage, the compressed aluminium is heated in a furnace until it melts. Once melted, the aluminium is processed and rolled into large sheets that are between 2.5 mm and 6 mm thick. These sheets are then used to manufacture new aluminium cans.
Finally, the newly produced cans are reused by consumers. After use, they can once again be placed in recycling bins, continuing the cycle. This recycling system helps reduce waste and saves natural resources.
