Aluminium coffee capsules: recycling that turns waste into resources

The key to this technology lies in the sorting plant at Muggiano, on the outskirts of the Lombardy regional capital, where a specialised separator has been installed, capable of recovering aluminium fragments that would normally be lost. In addition to capsules, the system is also able to sort small metal items such as bottle caps and blister packs. The initiative also represents a first concrete example of the application of the future European PPWR regulation. The principle introduced by the new legislation is clear: the correct sorting of waste by the public must result in genuine and effective recycling. However, this will only be possible in areas equipped with the appropriate technologies.

Nespresso’s commitment to the recovery of aluminium capsules goes back a long way. As early as 2011, the company launched the “Da Chicco a Chicco” project, a dedicated capsule recycling scheme operating throughout Italia, with over 300 collection points – including Nespresso shops and partner recycling centres – where used capsules can be returned. The model involves the separate recovery of the two materials that make up the capsule. The aluminium is remelted and reused, whilst the used coffee grounds are turned into compost for use in rice paddies. Supplies of rice grown from these paddies are then purchased for donation to Banco Alimentare and Fondazione Progetto Arca, thereby also creating a positive social impact.

In Lombardy, the project has already enabled the recovery of thousands of tonnes of capsules. “The system works because it is dedicated and built around a specific supply chain,” explained Monica Pellegrini, Chief Operating Officer of Nespresso Italiana, emphasising that the new regulatory framework now makes it necessary to complement 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 classified as packaging and must therefore be placed in separate collection schemes. However, the new regulatory framework alone is not enough. There is a risk that correct disposal will not automatically translate into effective recovery if the facilities are not equipped to process small pieces of aluminium.

This is why the Milan model is being closely scrutinised at national level too: it demonstrates that recycling can work when technology, infrastructure and industrial collaboration are all moving in the same direction. Collaboration between the public and private sectors is therefore essential.

This is precisely the challenge we face in the coming years: to transform an everyday activity 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.
