Ternua And Archroma join efforts on
recycling and upcycling nutshell waste into fashion
Archroma, a global leader in color and specialty chemicals
towards sustainable solutions, announced collaboration with
Ternua, an outdoor brand with a strong connection to nature.
Ternua has partnered with Archroma, and its 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
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.

Archroma’s EarthColors® to create a capsule
collection that reuses agricultural waste and
applies it to garments, avoiding the use of
artificial dyes. (Photographs: Ternua)
The Nutcycle collection has attracted visitors’ attention at
the recent Outdoor Show in Friedrichshafen, and it will be
available in shops in February 2019.
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 55,000 kg of walnuts are consumed in the
Basque region’s cider houses. The collaboration with Archroma
aimed at using walnut shells to make biomass-based dyes to color
The fabric, a blend of post-consumer recycled cotton and
polyester, is dyed using the shells collected from four nearby
cider houses 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.
