I had a similar thought, but I wonder how much a 'powder' would qualify as microplastic - can a microplastic be so small that it doesn't have the same food-chain impact as slightly-larger microplastic? Is it possible to make a substance that is universally 100% excreted by every organism?

> Is it possible to make a substance that is universally 100% excreted by every organism? First of all, it is very unlikely. But even if it could be theoretically possible, I very much doubt anyone would spend money to make it universally excretable. They will stop at humans, and maybe (luckily) at mammals.
