For our Nespresso compatible capsules we choose to use aluminium. We’ve learnt a lot about capsule technology over the years and we feel strongly that aluminium is the best solution on the market. Aluminium is the most abundant metal on earth and is infinitely recyclable. In actual fact, 75% of all aluminium produced is still in use today. Not only that, but if recycled, it has the lowest total carbon life cycle of any coffee capsule material. That’s why we made the decision to use this awesome material for our range of flavoured nespresso® compatible capsules, and yes, they are 100% recyclable!
