Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves pyrolyzing one or more waste plastics into various pyrolysis products, including a carbon solids-containing pyrolysis residue, and then subjecting the pyrolysis residue to partial oxidation gasification to thereby form a syngas composition.
