I would imagine that its not economically viable at scale. First, it might be too energy-intensive for the value of the end product, and second, the plastic you can get is still the plastic that you're able to separate from trash, which it might be better to just recycle it normally. These are just peanut-gallery guesses though, I don't know for sure.
