The fashion industry is responsible for as much as 10% of annual CO2 emissions and an immense amount of waste that chokes landfills, rivers, and beaches worldwide. Too much of our clothing is made from oil-based textiles, like polyester. Tessa Callaghan, cofounder and CEO of Keel Labs, has been recognized as a Forbes 30 Under 30 leader for her contributions to plant-based fashion. The Morrisville, North Carolina-based early-stage startup has developed a kelp-based alternative called Kelsun. According to the company, Kelsun is a compostable, soft natural fiber that can be integrated into the clothing production system with no changes. The result is clothing as comfortable and durable as those made with water-intensive cotton or oil-based textiles.

After beginning her career in the fashion industry, Tessa recognized the growing demand for sustainable alternatives to clothing that’s bad for the environment at every step in the lifecycle. Keel Labs converts kelp into Kelsun, and the resulting fiber is compostable at the end of its useful life, making it a potentially circular material we can be proud to wear.
