1. A method of producing circular chemical products comprising:
providing a coker gas that is at least partially derived from polymeric waste, wherein the coker gas has an olefin content of about 10 wt % to about 30 wt %, a sulfur content of about 0.5 wt % to about 5 wt %, and a total halide content of about 1 wppm to about 150 wppm; and oxygen-containing compounds in an amount of about 0.5 wt % to about 15 wt %; and
converting the coker gas into at least a polymer.
