Aluminium coffee capsules, recycling that turns waste into resources

The technological key is to be found in the sorting plant in Muggiano, on the outskirts of Lombardy's capital city, where a special separator has been implemented, capable of recovering aluminium fragments that would normally be dispersed. In addition to capsules, the system is also able to select small metal elements such as caps or blisters. The initiative also represents a first concrete example of the application of the future European Ppwr regulation. The principle introduced by the new regulation is clear: the correct disposal by the citizen must result in real and effective recycling. But this will only be possible in territories equipped with the appropriate technologies.

Nespresso's commitment to the recovery of aluminium capsules goes back further. As early as 2011, the company developed the 'From Chicco to Chicco' project, a dedicated capsule recycling system, active throughout Italy, with over 300 collection points where spent capsules can be returned, including Nespresso shops and partner ecological islands. The model involves the separate recovery of the two materials that make up the capsule. The aluminium is re-melted and reused, while the spent coffee is turned into compost used in rice fields. From the cultivated rice, supplies are then purchased for Banco Alimentare and Fondazione Progetto Arca, thus also creating a social impact.

In Lombardy, the project has already allowed the recovery of thousands of tonnes of capsules. "The system works because it is dedicated and built around a precise supply chain," explained Monica Pellegrini, operations director of Nespresso Italiana, emphasising how the new regulatory scenario now makes it necessary to flank dedicated systems with broader collective models.

The entry into force of the Ppwr will mark a paradigm shift for the entire packaging sector. Coffee capsules will be recognised as packaging and will therefore have to be included in separate waste collection systems. But the new regulatory framework alone is not enough. The risk is that correct disposal will not automatically translate into effective recovery if plants are not equipped to intercept small aluminium.

This is why the Milan model is also being closely observed at national level: it shows that recycling can work when technology, infrastructure and industrial collaboration move in the same direction. Therefore, public-private collaboration is crucial.

The challenge of the coming years will be precisely this: to transform an everyday gesture such as drinking a coffee into a system capable of generating environmental, economic and social value. Because in the circular economy, waste is not the end of the production cycle, but the beginning of a new resource.
