Archroma, a global leader in color and specialty chemicals towards sustainable solutions has collaborated with Ternua, an outdoor brand with a strong connection to nature. Together they have created EarthColors®patented technology, to create a capsule collection of recycled tee-shirts and sweatshirts, collecting, recycling and upcycling agricultural waste from the Basque region in Spain after food consumption.

Archroma’s award-winning EarthColors® is a traceable concept of plant-based dyes, sourced from up to 100 percent renewable resources. Archroma developed EarthColors® using non-edible waste products, from agriculture and herbal industries, to replace petroleum derived raw materials; which are the conventional raw materials used to synthesize dyes currently. This gives brands an alternative when looking for more natural ways of dyeing garments.

The Nutcycle collection uses walnut shells to make biomass-based dyes to color Ternua’s collection. Ternua’s vision was to collect walnut shells during the cider season, when cider houses typically serve walnuts with cider. It is estimated that up to 55,000kg of walnuts are consumed in the Basque region’s cider houses. The collaboration with Archroma aims at using walnut shells to make biomass-based dyes to color Ternua’s garments.
