With SONNET155 we aim for a desirable product, which represents sustainability as a treat rather than a burden. The design of the bag follows a minimalist approach to enhance the texture and translucence of the material. he bag is fully biodegradable in water or soil as it is made from a composite of two raw materials, which can be sourced locally: cellulosic production waste from the textile industry and pectin, a plant-based polysaccharide and a by-product from juice production. The material is fully compostable and can be integrated within a biological life-cycle.
