Zusammenfassung:	Systems and methods for producing one or more olefins using waste plastics and used lubricating oil are disclosed. Mixed waste plastic is processed in a pyrolysis unit to produce plastic derived oil. The plastic derived oil is subsequently blended with used lubricating oil to form a mixture. The mixture is then separated into (1) a light-end stream comprising C1 to C8 hydrocarbons and (2) a heavy hydrocarbon feed stream. The heavy hydrocarbon feed stream is then processed to produce a steam cracking feedstock stream. The light end-stream and/or the steam cracking feedstock stream are then flowed into a cracking unit to produce one or more olefins.
