"AlgiKnit develops biomaterials from the most renewable and fasted growing organisms on earth - kelp, laminaria digitata to be precise, a large brown alga also known as oarweed. It grows up to 10 times faster than bamboo and is grown in aquatic farms around the world in coastal communities, often by fishermen and women, thus providing income for them during off-season."
