Burn it with plasma gasification to reduce it to the simple molecules to eliminate all the pollutants. CO2 is a much smaller and easier to manage problem than plastic waste.

By what possible measure? Despite clear, well documented science, including very clear dire economical impact, and all within an extremely clear and short term time frame, with escalating effects already visible literally everywhere in the world, we have had almost 0 progress in combating global warming. The best we've done is slowing the rate of acceleration - as in CO2 release is still accelerating, just not as much.
Plastic waste has environmental impact, especially in the oceans, but nowhere near to the level that 2-3-4 degrees warming will have. And that is what we are currently on track for by the end of this century.
