Human Material Loop

Human Material Loop is turning something most people throw away—human hair—into a powerful resource for the textile world. The materials science startup has developed a patented biotechnology that transforms hair waste into high-performance keratin fibers, offering a sustainable alternative for the fashion and interior industries.

Hair is one of the most underused waste materials on the planet. It’s everywhere, renewable, and packed with protein. By tapping into this overlooked resource, Human Material Loop creates a fiber that not only performs well but also comes with a significantly lower environmental footprint compared to traditional materials.

Their technology can be retrofitted into existing production systems, making it possible to collect and process hair locally in cities around the world. That means less transportation, lower emissions, and new opportunities for local jobs and circular economies. It's a system designed to make waste valuable—locally and globally.
