A Finnish startup has developed stylish new sneakers made from old coffee and recycled plastic bottles, thus cutting methane emissions as well as waste in landfills.
“As environmental awareness increases, so too does knowledge of the circular economy,’ says Jesse Tran, co-founder of the startup Rens. “Shoes made from recycled coffee grounds may seem novel to some, but we wholeheartedly believe that this is just the beginning of a revolution in garment technology and manufacturing.”
Each pair of sneakers require 21 cups of coffee and 6 recycled plastic bottles. So far 250,000 water bottles and 750,000 cups of coffee have been transformed into kicks that are waterproof, comfortable, and can absorb odors. How do they do it? They mix recycled plastic with coffee grounds in a low-heat environment to create coffee yarn for the upper section of the shoe. The sole is made from biodegradable milky tree sap.
