Probably the most common plant-based plastic is PLA. Or at least, that's the one I come across most often. While technically it's compostable, you need an industrial composting process to do it. It's not something you can just throw in the ground and dig up as usable soil a year later. And it's entirely possible that there would be ecosystem-unfriendly additives in it unless you were careful. This runs the same risk as we currently see with recycling: because it all happens behind closed doors, the door's wide open for the worst sorts of environmental fraud where the claimed process actually only happens on a small fraction of the input, and the rest is just dumped. We really need plastics that can be broken down at the home level so people can take ownership of the process directly.
