The diagram provide data on the multi-stage in which aluminium can is reuse.
Overall, it is clear from the diagram that the process consist various key stages, taking total 6 weeks to complete, beginning with waste is gathered and finishing with the products are ready for use.
At the first stage of the process, used aluminium cans are collected by garbage car during waste collection and delivered to a factory for consolidation. Following that, the collected items undergo an advance sorting steps, where a magnet is used to separate iron impurities form aluminium. Next, the can are transferred to a shredding maschine to be breakdown in small species before compressing into a cube through a stage called baling.
In the next step, the aluminium are fed to a introduction melting process before they pass through thermal de-coating to remove the remain paint. The molten metal is then casted into ingot by using molts, and these blocks experience purification and weighing. In the final phrase, the indgots are pass thought some rollers to be flatten into thin sheet in order to serve for material to forming and sharping can. The final stage of the recycle in when new cans is available for commercial use.
