Aluminium is one of the most commonly used metals in the world, but did you know that it can be recycled over and over again without losing its quality? Recycling aluminium not only helps to conserve natural resources but also saves energy and reduces greenhouse gas emissions. In this article, we will walk you through the step-by-step process of how aluminium is recycled.

1. Collection.

The first step in recycling aluminium is the collection of used aluminium products. These can include beverage cans, foil trays, window frames, and even car parts. The aluminium is then sorted and separated from other materials like plastic and glass.

2. Shredding.

After collection, the aluminium is shredded into small pieces using a machine called a shredder. This process helps to increase the surface area of the metal, making it easier to melt down later on.

3. Melting.

Once the aluminium has been shredded, it is then melted in a furnace at high temperatures of around 700 degrees Celsius. This melting process removes any coatings or impurities from the metal.

4. Refining.

After melting, the aluminium is refined to remove any residual impurities. This is done by adding various chemicals to the molten metal and stirring it to trap the impurities, which can then be skimmed off the surface.

5. Casting.

Once the aluminium has been refined, it is poured into molds to create new products. These molds can range from simple shapes like ingots to more complex shapes like car parts or window frames.

6. Rolling.

After casting, the aluminium can be further processed by rolling it into thin sheets or coils. This process involves passing the metal through a series of rollers to reduce its thickness and improve its strength and flexibility.

7. Finishing.

The final step in the recycling process is finishing the aluminium products. This can include painting, anodizing, or coating the metal to improve its appearance and durability.

Overall, recycling aluminium is a fairly straightforward process that can be repeated multiple times without compromising the quality of the metal. By choosing to recycle aluminium products, you are not only helping to protect the environment but also contributing to the circular economy.
