This is so disappointing (but not surprising).

Many years ago there was a lot of press about a company call Changing World Technologies (https://en.wikipedia.org/wiki/Changing_World_Technologies) that touted how they could use pyrolysis to convert any hydrocarbon feedstock into fuel (garbage, sewage, etc).

It was going to be cost competitive and clean. Turned out to be not so much when their pilot plant processing turkey remnants stank up the town and shut them down.

The technology seems to be valuable, but it looks like capturing and containing emmissions is still not cost effective so they just dump it.
