Can we have black knits and keep water fresh?

What we love:

  • Deep black t-shirts that look and feel great

But did you know?

  • 25 percent of all knits are dyed black
  • Dyeing black cotton knits requires a lot of water, energy, dyestuff and salt
  • The saline effluent has to be diluted so that it can be released without damage to local rivers, fish and fields
  • There are ways of doing this more efficiently, embracing circularity by re-using dye bath again and again

The Archroma Way to a Sustainable World: Safe, Efficient, Enhanced. It’s our nature.

1. SAFE – IT’S OUR NATURE TO PROTECT
A solid core: Our deeply rooted goal to protect people and our planet. Safe to use, safe to release and also safe to wear.

2. EFFICIENT – IT’S OUR NATURE TO RETHINK SUSTAINABLE MANUFACTURING
Innovating application processes that minimize resources and maximize productivity, both in our and our customers’ manufacturing as well as by setting ourselves ambitious sustainability goals.

3. ENHANCED – IT’S OUR NATURE TO ADD ANOTHER LEVEL OF VALUE
Innovation is critical. With it, we create additional effects, functionalities and aesthetics and sustainable differentiation to bring additional value, helping consumers to achieve their goals, for a life enhanced.
