In all attempts to recycle polymers into fuels, I strongly suggest to check what the residues are, and how toxic they are.
You might also check how much of the wrong polymers you can tolerate in the process. Usually, PE and PP can be transformed, PET too if separately, but as soon as a little bit of PVC is mixed in, the gases and the leftovers are really nasty. It's a fundamental problem hampering pyrolysis processes. Does photocatalysis achieve it any better?
Usually, plastic waste isn't a serious issue, while the leftovers of recycling are horrible. It's far better to have a bunch of PE, PP, PET in the ground than polycyclic aromatics or a random cocktail of organic chlorides.
PVC garbage is more an issue, but usually recyclers don't care about eliminating it.
