Pyrolysis gases from waste plastics have the potential to replace natural gas (NG).
PVC HCl-scrubbed pyrolysis gas is a suitable fuel for US and Europe NG burners.
PS pyrolysis at 900 °C is a possible source for US NG burners but not for EU burners.
The least conforming pyrolysis gases for NG burners are PE, PP, and PET.
PE gases have potential to replace propane in terms of keeping burner power.
