Appleskin is a leather-like material produced by the German company Nuuwaï. The material is PETA-approved vegan and consists of 26% apple waste, 38% polyurethane (PU), 20% polyester and 16% cotton. For the production of the material the apple waste is dried and milled into a fine powder, which is then mixed with PU and applied onto tear-resistant cotton fabric. The resulting material is long-lasting, water-resistant and Oeco-Tex 100 certified. While the apple waste is able to replace some of the PU, a certain amount is still needed to make the bags durable. However, Nuuwaï are currently working on a more sustainable solution of bio-based PU made from fermented biomass.
