The given diagram is a process chart which depicts how aluminium cans are recycled after they have been used.
At the onset, it is explicitly observed that, aluminium cans are discarded into dedicated bins by the public and then collected to be transported to a recycling facility. Subsequently, the cans undergo thorough cleaning to eliminate any impurities, such as dirt, grease, and other contaminants. Next, the cleaned cans are sorted in order to ensure that the chosen cans are suitable for recycling and to separate them from other waste materials.
Further, these sorted cans are shredded into smaller pieces and then crushed in a special machine to reduce their size and make them easier to handle.
Finally, the metal is then heated to a high enough temperature to allow the aluminium to melt. It is then rolled out flat to a thickness of between 2.5mm and 6 mm, depending on what it is going to be used for. The aluminium is now utilized for manufacturing new packaging, such as beverage containers. The new cans are delivered to a soft drinks factory where they are filled. The cans can now be sold to the public and reused. Almost the third quartile of the population of the United Kingdom uses recycled cans.
To give an overview, the overall trend makes it abundantly clear that there are six primary stages :reusing, collection, cleaning, sorting, shredding and compressing, heating and melting, and rolling for a specific thickness. As can be seen from the key feature, that recycling aluminium cans involves a meticulous series of steps and culminates in the production of new cans for public use. The main comparison is observed in that is the crucial role of heat in the melting phase of the recycling process.
