Where most alt-leathers require plastic-based binders or coatings to achieve the required durability, Mirum’s plant-based ingredients mean it is fully circular and bio-neutral. At the end of its life, it can either be remade or return as nutrients back to nature. It isn’t stuck in the pilot stage either, as brands such as Pangaia, Camper and H&M already have Mirum-based products in-market, and Natural Fiber Welding has now raised over USD 150 million to scale rapidly. May others follow fast in these new tracks.
