The use of cans in daily life is very common, and of course, they have become an important component of waste recycling materials. Based on the current recycling situation of cans, the recycling rate of aluminum cans in China is estimated to be around 82%, making it the country with the highest recycling rate of cans in the world. At least 160000 tons of cans are recycled annually, and the recycled cans are downgraded for use.

The application of recycling cans

The recycling and reuse of cans can not only save bauxite but also 92% of the energy consumed in aluminum smelting, making a huge contribution to protecting and beautifying the Earth's environment. 1/4 of the recovered amount is used as easy to pull can material for manufacturing, while the rest is used as raw materials for castings and die castings, used for producing automotive parts, motor parts, etc., and a portion is used as a deoxidizer for steelmaking. Making recycled aluminum ingots from cans and then making cans from recycled aluminum ingots can be reused multiple times. No matter how many times a can is recycled, its quality will not be reduced.

The recycling of cans involves producing alloy aluminum ingots and remelting to produce substandard aluminum ingots, which can be used in industries such as ferroalloys and steelmaking. It seems that this model is more in line with your current situation. For the production of substandard aluminum ingots by remelting method, under strict operation (whether reverberatory furnace or crucible furnace is used), the maximum direct yield of aluminum can only reach about 83%, including the inferior aluminum recovered from aluminum slag through refining.

Recycling process of waste cans

The collected waste cans are first subjected to simple flattening and compression treatment, followed by sorting and washing. The flattened and packaged cans are then crushed and shredded using a metal shredder or can crusher, and the materials are accurately sorted and removed by a sorting machine to obtain clean waste aluminum particles, which are then concentrated and "melted". At high temperatures, they become liquid aluminum and then transformed into large aluminum ingots. Finally, the cans will be melted into recycled aluminum ingots.
