Aluminum Recycling

Is aluminum infinitely recyclable?

Yes, aluminum is infinitely recyclable, and this means that it can be recycled repeatedly without losing any of its qualities.

Recycling aluminum

Recycling aluminum is extremely efficient, and only 5% of the energy invested in creating new aluminum must recycle the same amount. Because aluminum is infinitely reusable, there is no loss of quality once the recycling process is completed.

The following is the step by step aluminum recycling process:

Collection of scrap aluminum - Drinks cans, aluminum foil trays, and aerosol cans are collected from homes, streets, and garbage collection centers. Aluminum scrap can be mixed with steel scrap, and the scrap is gathered together and is transported to the aluminum recycling plant.

Sorting - The mixed scrap metal (aluminum and steel) is taken to a materials recovery facility, cleaned, and sorted into different metal streams. Magnets are used to separate metals, which leaves aluminum behind since it is non-magnetic. This step is crucial in ensuring that the aluminum is separated from other metals.

Shredding - After being taken to reprocessing plants, the aluminum is cut or shredded into small pieces. This is done to make it easier to get rid of all the paintings and coatings. Also, shredding is done to promote the melting process.

Cleaning - Using mechanical and chemical processes, the aluminum pieces are scrubbed clean to prepare them for melting.

Melting - Scrap aluminum is loaded into high-temperature, high-capacity furnaces and melted down at temperatures exceeding 700 degrees Celsius. A considerable amount of energy is used in this step. Still, the energy required to melt and recycle metals is much less than the energy needed to produce metals using virgin raw materials.

Purification - To purify the molten metal, various waste products created in the melting process are removed, either mechanically or through the use of chlorine and nitrogen gas.

Aluminum alloys are created by adding metals like copper, zinc, magnesium, or silicon to the molten mixture. Alloy formulas are chosen based on the planned particular uses for recycled aluminum.

Compounding - The molten metal is poured out and formed into ingots transported to aluminum processing or manufacturing plants to be made into new products.

Aluminum is recycled again and again. Nearly 75 percent of all aluminum is recycled globally.

Advantages recycled aluminum

Aluminum recycling is a critical process because of numerous advantages:

Energy savings - Recycling aluminum uses about 5% of the energy required to create aluminum from bauxite.

Environmental savings - Aluminum is a metal mined from the earth’s crust as Bauxite ore, and recycling aluminum prevents continuous mining and depletion of this precious commodity. Also, aluminum recycling saves around 95% of the greenhouse gas emissions compared to the ‘primary’ production process.

Reduction of Landfill - Although aluminum is one of the most recycled materials on the market today, aluminum still ends up in landfills.

Aluminum never wears out - Aluminum is infinitely recyclable without losing any of its qualities.

Aluminum recycling companies

Aluminum is valuable at every stage of its life cycle, from production through to the end of use. Aluminum recycling companies produce aluminum out of recycled metal, and they purchase primary metal to transform it into semi-finished products. Recycling aluminum is crucial to the environment and people worldwide, and all world economies need to embrace solid waste recycling and reduce carbon dioxide emissions.
