Flexible packaging is made from several layers of plastic, aluminum, and other finite materials, and by design, is not recyclable. Hundreds of billions of single-use pouches are created every year and none are recovered for reuse, wasting tons of valuable resources every day they are buried or burned.
Solutions: Recycled Paper-waxed pouchers without plastic sipper
This solution was suggested by Lorena from Spain/New Zealand
If the industry can't help but create single use products, then make them compostable and from recycled paper (or don't create them at all).
I suggest not using plastic sippers at all. Instead, create a waxed-paper elongation at the poucher, that you can just bite and sip from there. Simple, functional, comopostable (still not renewable, but better than plastic ones)
