Coffee grounds and food waste from seafood production can be a substitute for animal skins.
Ecological and biodegradable material was developed by Vietnamese designer Wen Tran. She named her alternative to Tômtex skin, which translates from Vietnamese as "shrimp".
Wen Tran pursues two goals at once: to develop a replacement for genuine leather, the production of which pollutes the planet, and to find the use of food waste. The designer noted that in a year the world food industry produces up to eight million tons of seafood waste and 18 million tons of coffee grounds.
To make leather, the designer uses shrimp, crab and lobster shells, as well as fish scales. From this raw material it extracts chitin, which makes the shells both strong and flexible. It then adds to the biomaterial the residue left after brewing the coffee. And then covers the resulting fabric with beeswax, which makes it waterproof.
