I’ve heard the rayon process, which can take (m)any natural fiber source and convert it into something vaguely like a synthetic silk, has quite a pollution footprint. The more you have to process the fibers to be like a niche or synthetic fiber the more it becomes greenwashing. Method Inc went through a phase where they made containers out of virgin materials because the overall ecological footprint was several times better than the best we could hope for plastic recycling, and that was before we found out plastic recycling is half sham. A lot of the trick was making thinner containers out of specialty materials that were lower volume than the waste stream from plastic recycling. Eventually they figured out a recyclable material that is as light as the disposable ones, so they get the best of both worlds. Unfortunately they only use those for hand soap refills.
