That's the real question. It doesn't "eliminate" anything. It turns it into - what? Organic sludge? Is that useful for something?

Plastic bottle recycling into new plastic pellets works quite well. Southern California has a huge plant doing it. Non-bottle plastic is more of a problem but less of the volume.

Nothing eliminates anything. It's all CxHy + zO2 -> nCO2 + mH2O

There is such thing called second law of thermodynamics.

The only question is into how much stages we can split this process, and how much useful stuff we can extract from each of those.
