AlgiKnit, US-based manufacturer of sustainable materials, has changed its name to Keel Labs and debuted a seaweed-based yarn with a lower environmental impact.

To create its yarns, Keel Labs extracts a component from seaweed and combines it with renewable biopolymers. Then, the yarn can be knitted into fabrics and dyed. 

This new product offers an alternative to current methods of yarn production, which are often highly polluting and resource-intensive.

Tessa Callaghan, co-founder and CEO at Keel Labs, explains that the name Keel Labs encompasses their vision of ever-expanding horizons, of their commitment to innovation and opportunity.

“Our work begins with fibre, but our responsibility does not end there,” added Callaghan.

“We are building a future in which sustainable materials harness the power of our oceans to span industries and applications, repairing humanity’s relationship with our natural ecosystems.”

Founded as AlgiKnit in 2017, Keel Labs is a sustainable materials company taking action to solve polluting systems of textile production with aquaculture-based technologies.

The company’s goal is to position itself as a hub for innovation, with future products that will enhance the potential of the ocean to accelerate the planet’s development toward a more sustainable world.
