Black Algae T Shirt
We’re using nature to rethink how clothes and even colour are made.
- Printed with black algae ink
- Soft and highly breathable
- Extreme four way stretch
The colour black is everywhere. From our phones to our cars to the ink in our pens. But black has a dark side. Every black thing you own is likely to contain carbon black – a pigment derived from petroleum. The way carbon black is made isn’t sustainable. Vast tracts of land called tar sands are stripped of all life and vegetation to extract the heavy petroleum, while the production process creates significant greenhouse gases.
So we’re on a search for the new black. Our aim is to reinvent the way in which the colour itself is made. And it all starts with a t shirt made with black algae. You don’t have to dig up the earth to find black algae. It grows in ponds using sunlight and carbon dioxide. Not only does algae generate more than half the oxygen on Earth, but once it becomes part of this t shirt, it captures and stores the carbon it used as its fuel for the next 100 years.
In 2021 we released the first Black Algae T Shirt with the base of the t shirt built from pulped eucalyptus. Version 2 is built with one of the most misunderstood yet futuristic materials on the planet – hemp.
Technical Details

We’re working with a US biomaterials startup
With the help of US biomaterials company Living Ink, we’ve found a method of making our t shirt without using any carbon black. After their founders Scott and Steve discovered that an algae cell is almost identical in size to a carbon black pigment, and can create the same colour, they’ve been on a mission to replace carbon black ink with a black ink made from black algae waste.


Built with carbon capture technology
Once the t shirt has been built and printed, the black algae ink continues to lock in the carbon dioxide that it absorbed when it was alive. And it will do this for over 100 years. So the t shirt you’re wearing is storing carbon emissions. This is known as carbon capture technology and it means that rather than producing emissions, the Black Algae T Shirt does the exact opposite.
