Aluminum-free, adj. Aluminum is widely used as a packaging material for coffee, both as a capsule and as the inner coating of coffee bags. Production is immensely energy-intensive*. In addition, its production from bauxite produces toxic waste products such as red mud. And: as the large bauxite deposits are located in the tropical belt, rainforests are being cut down to make way for them. That is why we have opted for an aluminum-free, recyclable and yet aroma-safe packaging material. This is a small challenge for the filling process, but it is worth it.
