What's the point of this when incineration is an option? Even its wikipedia page has only negatives compared to incineration.

> Air emissions can be cleaner than landfills and similar to that of incinerators.

> Large initial investment costs relative to that of alternatives, including [...] incineration.

> Operational costs are high relative to that of incineration.

I think you misread the Wikipedia page. Plasma gasification air emissions are cleaner with costs being somewhat higher than incineration. Plasma gasification breaks matter down at the molecular level versus combustion of incineration. With plasma gasification, you are paying more to end with a more inert end material and reduced hazardous process byproducts.
