Creating sustainable aluminum

Recycling aluminum is now standard sustainable protocol, but what about aluminum production? As we learned at day one of Sustainability in Packaging Europe, Barcelona, efforts in the industry are under way to make aluminum sustainable, from start to finish.

Luxury coffee producer Nespresso’s relationship with aluminum spans 40 years. However, it has not always been a smooth ride. Creating aluminum is not a simple mining process – the raw material bauxite ore is mined and refined into alumina, a white granular material. Alumina is then electrolyzed into aluminum metal. Product manufacturing and use - including scrap collection, refining and melting of the scrap are the final steps. And, because bauxite is mined horizontally from the topsoil, it can cause land and human disruption, as well as the use and contamination of other natural resources.

Why then did Nespresso choose aluminum to create it’s portioned capsules? Because aluminum offers the best protection from oxidation, and preserves coffee freshness, according to Christophe Boussemart, Sustainability Manager at Nespresso. Portioned capsules also prevent food waste through leftovers. (Boussemart said the kitchen sink consumes the most coffee made by standard drip coffee pots.)
