There is no going back about cleaning plastics by traditional methods now unfortunately.
The only real solution I see is if we bio-engineer some bacteria/microorganism capable of decomposing it and release it in the environment. It might be a danregous proposition, but (expect the even more advanced and potentially dangerous proposition of nanites) I can't see any other way of getting rid of all the plastic we already put into the environment even if we stop producing it.
