Lazer

I recently did an experiment where I used mixed plastic (Rubber, PVC etc.) and burned, and condensed them to form oil. The problem with this is that is also forms HCl of PH 1 which is very dangerous and due to this HCl being produced the experiment cant be used in the real world on a large scale. Is there a way to prevent this HCl from being produced. From my research i found that the HCl is being produced because of the PVC present in the mixed plastic, is there a way to segregate the PVC.
