Seaweed! But the word "seaweed" alone is about as useful as the word "plastic"; there are are so many different kinds that the word alone is not very informative. I couldn't find any information on just what kind of seaweed the subject company is using, either in the article or the company's web site. If it's kelp, it's problematic because kelp is sensitive to climate change and kelp forests are in a state of collapse around the world. Individual kelps can grow fast, but it can take a long time for new kelp forests to take root and spread. If it's sargassum, which floats freely in the ocean and seems to be thriving in the new climate regime, then we may have something.
