Upcycling is a special form of recycling in which low-grade raw materials such as waste or even leftover residual materials are used for the production of a new product . In the case of our bio-based AirPods cover, we use old Cases and agricultural waste, saving a lot of resources and reducing polluting emissions by up to 75%. Plus, you can easily send your used Case back to us and we'll recycle it for you, for a perfect recycling loop!
