The diagram illustrates the process of recycling aluminum drink cans.
Overall, there are five main stages in this man-made process, beginning with the collection of used aluminum cans and ending with their reuse in drinks machines.
The process starts when used aluminum cans are collected from recycling bins and taken by truck to a recycling center. There, the cans are sorted and sent to an aluminum recycling plant. In this plant, the old aluminum is melted down and then molded into new shapes. After that, the new aluminum is rolled into thin sheets, which are used to manufacture new cans.
In the final stage, these newly made aluminum cans are filled with drinks and placed in vending machines to be sold to consumers, completing the recycling cycle.
