It's time to recycle...
ALUMINUM RECYCLING
A.Aluminum recycling is, of course, a process completed through certain stages. If we look at the recycling stages, each stage of which is carried out meticulously:
1- Aluminum Scrap Collection
As in all recycling activities, products containing aluminum are collected in the first stage. Although very large products are already purchased with certain agreements or for some considerable fees, there are also aluminum foil trays, tin beverage cans, etc. that we use in our homes and daily lives. Products are also collected by garbage collectors and therefore garbage collection centres.
2- Classification
The classification stage is also an important stage of the aluminum recycling process. Because not every product containing aluminum is subject to the same recycling process. This would be wrong practice. Therefore, in order to carry out this classification and cleaning of the incoming products, all products are taken to recycling facilities and undergo detailed separation and cleaning stages. The products classified and cleaned here are compressed and turned into bales.
3- Shredding
Aluminum products formed into bales enter the grinder within the facilities and are ground until they are broken into tiny pieces. The reason for this disintegration is to ensure that the paints, coatings and adhesives on the aluminum that has previously been turned into a product easily lose and become pure aluminum. Additionally, it will be easier to melt the shredded product since these parts will be melted for recycling.
4- Separation with Magnet
Magnet separation is a precautionary step. With the help of a magnet that stays on the shattered aluminum for a long time, if there is still a piece of steel left inside, it is aimed to collect it and leave the aluminum pure and unadulterated. Although separation is done initially, this process is done to take extra precautions.
5- Removing the CoatingI
After all these stages, the remaining aluminum is not ready to be melted yet. Because the painting and coating etc. left over from previous uses also need to be separated. For this reason, hot air is blown onto the grated particles and all paint and coatings are evaporated and made ready for melting.
6- Melting Stage
Pure aluminum pieces, now free of everything else, are melted by throwing them into 7000 degree furnaces. During this process, special chemicals are used to float the slag and similar layers that will emerge after melting, making it easier to separate them after melting.
7- Transfer to the Holding Furnace
The melted aluminum is transferred to the holding furnace and kept there until it is ready to be poured into ingots. After the molten aluminum in this furnace is ready, it is regularly poured into molds and turns into blocks or ingots.
8- Transportation of Ingots
In this final stage, the ingots are removed from the pits and transported to the necessary facilities. These ingots are then rolled to form thin aluminum sheets. This process allows the aluminum sheets to become more flexible and durable. After this process, it becomes ready for reuse.
Aluminum recycling goes through all the processes you have seen and is re-used. The good thing is that all these processes can be completed at a much lower cost than the initial production of aluminum metal.
