The illustration below outlines the process of recycling used aluminum cans. Overall, the process consists of seven distinct steps, beginning with the collection of used cans and culminating in the reuse of these recycled cans, thus conserving aluminum resources.
Initially, used aluminum cans are collected from recycling bins and transported to a recycling plant. Upon arrival at the plant, the cans undergo sorting based on size and other characteristics. Following this, the sorted cans are meticulously cleaned to remove any contaminants, ensuring they are safe for subsequent use. The clean cans are then compressed and shredded into small aluminum pieces.
Next, these shredded pieces are fed into a large furnace where they are melted down to form liquid aluminum. Once the aluminum has been melted and subsequently cooled to a semi-solid state, it is passed through roller mills to achieve the desired thickness, typically between 2 and 6 mm.
In the subsequent stage, these aluminum sheets are purchased by various companies and organizations for the manufacturing of new products. A portion of these sheets is specifically recycled to produce new aluminum cans. Finally, these newly manufactured cans are distributed to grocery stores and supermarkets where consumers can purchase them. This entire recycling process not only reduces the need for raw aluminum but also significantly contributes to the preservation of natural resources and reduction of waste.
