Whether used for coffee, tea, or baby food, capsules made from aluminum or plastic are now a must-have in many households. To improve their ecological footprint, Greiner Packaging is currently working on a solution made from compostable polymer, so that customers can easily recycle used capsules on their own backyard compost heaps. The process of having the sustainable packaging certified by TÜV AUSTRIA BELGIUM nv started in February, with completion expected in the fall.
