AlgiKnit extracts alginate from kelp by adding certain salts to the seaweed base. After the so-called “salt bath” pulls the alginate from the kelp’s cell walls, the biopolymer is extracted from the seaweed residue, dried into a powder and fused into a yarn that can be turned into a variety of Fleece Fabric types. “The process is similar to that of synthetic materials, where one long continuous strand is produced,” says Tessa Callaghan, the co-founder of AlgiKnit. “The filament can be plied and twisted to increase strength, or cut into short fibers for other purposes.” AlgiKnit won National Geographic’s Chasing Genius Competition for developing this technology.
Using yeast to grow collagen eliminates the animal part of the equation—including slaughter and subsequent hide processing. It yields higher quality materials—perfectly shaped hides without branding marks or scars, and yields very large spans of leather, much bigger than a cow’s body. It also offers nearly endless creative design ideas. The new collagen can be sprayed on top of another Polar Fleece Fabric to create never-before-seen leather fashions, like the t-shirt that is currently on display at the Museum of Modern Art in New York as part of its Items: Is Fashion Modern? exhibit. This material can also be embossed or textured in ways that cow or pig leather just can’t.
Modern Meadow will be introducing Zoa to market in 2018. The production facilities are already available from related industries such as biofuels. “We use 200,000 or 500,000-liter fermentation tanks [for the yeast],” says Schofer, “So the infrastructure already exists around the globe to take this from lab to commercial levels.”
