One pair of new sneakers can be made with 21 cups of coffee and 6 recycled PET bottles. The coffee grounds are combined with the rPET at low temperatures to create a coffee yarn that is spun into the upper part of the shoes. The outer sole is made of biodegradable natural rubber.
In total, about 250,000 water bottles and 750,000 cups of coffee have been processed into these shoes. This prevents a lot of waste and greenhouse gas emissions. “We believe this is just the beginning of a revolution in clothing technology and production,” says Jesse Tran, the co-founder of Rens.
Rens’ sneakers are available in 9 different colours, are waterproof and comfortable. In addition, they absorb odours and, according to the makers, they are designed to be easy to put on and take off. Also available are matching socks made of coffee yarn.
