Only if they are 100% bioplastics, and 100% biodegradable in nature, not just in an industrial facility, or else you can end up with the same microplastics poll

Only if they are 100% bioplastics, and 100% biodegradable in nature, not just in an industrial facility, or else you can end up with the same microplastics pollution problem. Although different chemicals are likely to have dramatic different impacts on the environment, hopefully by now we've learned that "dumping a bunch of microparticles into the environment and hoping everything is OK" is a bad way to go about things.
