Are propylene and isobutylene really in such high demand that this process is worthwhile, as opposed to chucking all plastics (without sorting) into a plasma gasifier, which for plastics generates just syngas?
Out of curiosity, how often are new plastics invented, and how often are those plastics difficult to recycle?
For example I'm finding that modern computer cables are sheathed in a much more durable (less brittle) form of plastic than those from 10+ years ago. Or is that just the addition of pthalates?
Edit: plasma gasification does still produce tar, as per [1], but much less than standard gasification. There isn't much review on the effects of applying plasma gasification to plastics.

Is there any downside to using a plasma gasifier? I still see a lot of plastics around, so I guess(?) additional solutions are needed.
