Berlin-based Material designer Lobke Beckfeld and artist Johanna Hehemeyer-Cürten created SONNET155, a reusable tote bag made from a composite of two raw materials: cellulosic production waste from the textile industry and pectin, a plant-based polysaccharide extracted from skin leftovers that are a by-product from juice production. The translucent composite has leather-like properties and is fully biodegradable in water or soil. The design of the bag follows a minimalist approach to enhance its texture and translucence. Each bag is a one of a kind piece, unique in its gradient pattern, subtly varying textures and vivid pastel colours, which derive from natural pigments.
