Aluminum is an extremely valuable material for the ecological transition, thanks to its potentially infinite recyclability and key role in the circular economy.

In this article, we explore how sustainable aluminum is, its recycling process, the environmental and economic benefits of its reuse, and how Italy is progressing in this area, especially in light of the new European packaging regulations (PPWR).

How sustainable is aluminum?

Aluminum is one of the most sustainable materials available on the market. It can be recycled endlessly without losing its physical and mechanical properties, such as malleability, conductivity, gloss, and impermeability. This means that an aluminum package (once properly collected) can be reborn as a new can, automotive part, or even architectural element, contributing to lower energy consumption and CO₂ emissions.

Producing aluminum from recycled material results in energy savings of up to 95% compared to primary production. This figure highlights the significant environmental (and economic) value of recovering this metal.

How is aluminum recycled?

The aluminum recycling process is divided into several key stages:

• Collection: This takes place through municipal or industrial waste collection systems.

• Sorting: At treatment facilities, aluminum waste is separated from other materials -usually with magnets- and then compressed into bales;

• Melting: The aluminum bales are melted at around 700°C in dedicated furnaces.

• Casting and Rolling: Eventually, the liquid metal is cast into ingots and turned into new semi-finished products.

This efficient, low-impact process transforms waste into new raw material, ready to be reintroduced into the production cycle.

Why recycle aluminum? Key benefits

The benefits of recycling aluminum are wide-ranging:

• Environmental: Reduced CO₂ emissions, energy and resource savings, and lower waste volume.

• Economic: Lower production costs, new green economy opportunities, and increased value of a strategic material.
• 
  Social: Growth of sustainable supply chains and increased employment in the recycling and waste management sectors.

Recycling aluminum also helps reduce dependency on raw material imports and supports a more resilient, circular production system.

Circular economy

A circular economy is an economic model capable of regenerating itself, ensuring a high level of environmental sustainability. Within this context, the aluminum supply chain stands as one of the clearest examples of a circular economy model in action.
Thanks to its ability to be recycled infinitely without any loss in quality, aluminum helps build a virtuous cycle where waste becomes a valuable resource rather than mere discard.

Italy’s aluminum recycling achievements in 2024

In 2024, Italy achieved major milestones in aluminum recycling. According to CiAl (National Consortium for Aluminium Packaging):

• Aluminum packaging placed on the market: 91,500 tons of aluminum packaging were introduced into the Italian market.

• Aluminum recovered: 62,400 tons of aluminum packaging were recycled, covering 68.2% of the market.

• Energy savings: These recycled quantities resulted in energy savings equivalent to 197,000 tons of oil, avoiding the release of 442,000 tons of CO₂ into the atmosphere.

These figures confirm Italy’s leading role in Europe in aluminum recovery.

Keeping up with regulations: recycled aluminum and the PPWR

The new European Packaging and Packaging Waste Regulation (PPWR) aims to reduce the environmental impact of packaging by promoting recyclable materials and higher recycled content.
Aluminum fits perfectly into this framework due to its full recyclability and suitability for mono-material packaging, which is easier to process. The PPWR also encourages minimum recycled content targets; targets that aluminum can meet without compromising on quality.

This regulation offers a concrete opportunity to highlight sustainable materials like aluminum and to promote increasingly responsible and transparent production chains.

In conclusion

Recycling aluminum is a strategic choice for the environment, the economy, and society. With a strong supply chain, high recovery rates, and policies increasingly focused on sustainability, aluminum stands out as a crucial ally in building a circular future for both Europe and Italy.
