Ternua has joined efforts with Archroma, a global firm focusing on color and specialty chemicals aiming for sustainable solutions, to create a capsule collection of recycled tee-shirts and sweatshirts from nutshell waste. The collection, called Nutcycle, uses recycled and upcycled agricultural waste from the Basque region in Spain after food production, and applies it to garments, avoiding the use of artificial dyes. The walnut shells are collected from four cider houses where walnuts are traditionally consumed with cider, and then converted into dyestuff by Archroma in its Barcelona facilities. The project is supported by the Department of the Environment of the Gipuzkoa province government, and by the province's National Cider Association. The Nutcycle collection was on display at the recent OutDoor Show in Friedrichshafen, and will be available in shops starting in February 2019.
