What recycled aluminum is and why it's a key material for the circular economy
Recycled aluminum is aluminum that has already been used, whether as processing scrap or end-of-life products, and is remelted and transformed into new raw material ready for industrial use. Unlike many other metals, aluminum can be remelted and reused indefinitely without altering its original mechanical properties: lightness, strength, and workability remain intact through every cycle.
This characteristic makes recycled aluminum one of the pillars of the circular economy applied to manufacturing. Every ton remelted avoids the extraction of new bauxite, reduces the energy required for the production process, and limits material loss along the supply chain.
At Profall, we source raw materials from certified suppliers that can guarantee traceable recycled content and "second life" alloys compliant with international environmental regulations. This approach allows us to offer high-performance aluminum profiles without compromising on environmental impact.
How aluminum is recycled: the process step by step
The aluminum recycling process follows precise stages designed to ensure a final material free of impurities and with consistent mechanical properties:
- Collection and sorting: processing scrap and end-of-life products are collected and separated by alloy and type, ensuring a uniform input material.
- Decontamination: the material is cleaned of paint, oils, coatings, and other residues that could compromise the quality of the melt.
- Shredding: the scrap is reduced into uniformly sized fragments to enable a faster, more efficient melt.
- Melting: the material is brought to melting temperatures that are generally lower than those required for primary production from bauxite, resulting in significant energy savings.
- Impurity removal: slag and oxides are removed during melting to obtain a homogeneous, defect-free alloy.
- Billet casting: the molten aluminum is cast into billets, the starting form required for the extrusion process.
The result is raw material ready for extrusion, offering the same technical properties as primary aluminum but with a significantly smaller environmental footprint.
How many times can aluminum be recycled without losing quality
Aluminum can be recycled a theoretically unlimited number of times without its mechanical properties deteriorating. This characteristic sets it apart from many other industrial materials and makes it a reliable resource for anyone seeking consistent performance over time.
For sectors that demand high standards of safety and reliability, such as automotive, energy, and electronics, this means being able to rely on recycled aluminum components that meet the same technical requirements as primary materials. Mechanical strength and workability remain unchanged regardless of how many remelting cycles the material has already gone through.
This reliability is why recycled aluminum is no longer seen as a fallback alternative, but as a first-choice material for complex technical projects.
Why recycled aluminum is strategic for modern industry
Choosing recycled aluminum goes beyond environmental responsibility. It offers significant strategic advantages for industrial companies:
- Reduced environmental impact and emissions: recycling aluminum saves up to 9 tons of CO2 for every ton remelted, compared to production from virgin raw material.
- Lower energy costs: remelting aluminum requires up to 95% less energy than primary production from bauxite, directly impacting operating costs.
- Compliance with regulations and ESG criteria: using traceable recycled aluminum helps companies meet strict environmental regulations and achieve verifiable ESG goals.
- Competitive advantage in the automotive, energy, electronics, and industrial sectors: demonstrating the use of certified, low-impact materials strengthens a company's reputation and meets the demands of supply chains focused on sustainability.
Recycled aluminum in extruded profiles: how to integrate sustainability and performance into your project
Integrating recycled aluminum into an extruded profile project requires specific technical expertise. Processing recycled aluminum through extrusion follows the same principles as primary aluminum, but requires even tighter control over alloy composition and process parameters to ensure a final product that meets the required specifications.
At Profall, we work with 1000, 3000, and 6000 series alloys, including 1050, 1070, 3003, 3103, 3004, 6060, 6063, and 6005, selected according to each customer's application needs: from the electrical conductivity of 1000 series alloys, to the corrosion resistance of 3000 series alloys, to the workability and weldability of 6000 series alloys, typically used in custom-designed extrusions.
Tolerance control remains an essential step: on our standard profiles, we maintain dimensional tolerances of up to +/- 0.15 mm in diameter, a level of precision that ensures full component compatibility even in the most complex projects.
Working with an expert technical partner makes the difference. From initial feasibility assessment to alloy selection, all the way to quality control on the finished product, Profall supports its customers through every phase of the project, delivering recycled aluminum profiles that combine sustainability, precision, and reliability.
