Why we’re here

Everyone owns a pair of jeans - they’re a wardrobe staple. But the untold story in the denim industry is that the very substance that gives jeans their iconic look, indigo, is polluting our planet.

Today, chemically synthesized indigo is the industry standard for dyeing jeans. It is made from petroleum, formaldehyde, and hydrogen cyanide. And because indigo isn’t water soluble, it requires water polluting corrosive reducing agents to be applied as dye. These toxic chemicals in the denim dyeing process are hazardous for workers and ruinous to water sources.


Planet: Sustainability is in our DNA

Our reason for being - we put the planet first in every decision we make

People: Doing Good is For Everyone

Being informed and making responsible choices is for everyone, and so is our denim.

Progress: Inspired to Act

We’re pushing the envelope and encouraging our community to do the same in their everyday choices.


What we’re doing

For the last century, this problem has persisted as the status quo, untold and unresolved. Existing solutions are either unscalable or insufficient - until now.

We at Tinctorium have discovered a way to harness the power of biotechnology to enable sustainable indigo production. We figured out how to mirror a natural plant process within microbes to produce colors using completely renewable sources. We’re the sustainable solution for the future, and we’re taking on the denim industry to bring you cleaner jeans.
