Its a weird duality, right. Like, great you can get bacteria in a lab to eat plastic or found some bacteria in a specific place that can do it. But with how pervasive micro-plastics are you'd need this bacteria to be ubiquitous across soil and water globally while also not disrupting existing micro-biomes. Otherwise its just going to be in some sort of plastics processing facility and only be used in places where government policy forces their use or a useful biproduct is created from the processing that creates a market motivation that keeps the plastic out of the trash.
