disposes common organic waste by gasifying it into flammable compounds that is totally unrelated to fusion or nuclear waste.

There may still be some toxic substances remaining after the plasma process breaks everything down to basic atoms. Arsenic is still Arsenic, radioactives are still radioactive.

Another method is using fusion to burn up wasted fission fuel:

This fusion process involves neutronic fusion, not the aneutronic fusion/fission of Focus Fusion. FF could not be used for this unless alpha particles could be used instead of neutrons.
