Textile yarn from marine algae

Algiknit is developing biomaterials for the fashion industry from what is called 'the most renewable organisms on earth'. Addressing the ecological damage caused by the fashion industry, AlgiKnit is creating durable yet rapidly degradable yarns from kelp. Kelp is a type of seaweed or macroalgae, that is grown globally in cold coastal waters primarily in the northern hemisphere. Kelp absorbs CO2 and works against global warming and ocean acidification and also absorbs farm run-off. AlgiKnit’s yarns are directed toward use in the fashion industry, in particular within the fields of footwear, accessories, interiors, and garments.

While worn, the materials are durable and practical, only degrading when exposed to humid, fungi rich environments found in composting facilities for a prolonged period of time.
