The diagram delineates the sequential stages involved in the recycling process of aluminium cans.
In summary, the recycling procedure encompasses two principal phases: the preparatory stages and the processing stages. Notably, the entire operation is completed over a six-week period, utilizing minimal equipment and primarily one raw material to manufacture new cans.
The preparatory stages initiate with the collection of discarded aluminium cans by a dedicated truck, followed by their deposit at a recycling facility. Subsequently, water is applied to the cans, ensuring that they are properly cleansed. This is succeeded by the crushing process, wherein the cans are compacted into manageable pieces, thereby facilitating easier handling and processing.
After the initial preparation, the core processing stages commence. The crushed aluminium is subject to a chemical treatment to eliminate impurities before being subjected to high-temperature heating in an industrial oven, which effectively melts the material. The molten aluminium is then poured into molds to achieve the desired shapes. Following the molding, the aluminium is weighed to ensure that it meets precise specifications. The final stage involves rolling the aluminium sheets using specialized machinery, culminating in the production of new aluminium cans, which are then ready for distribution.
