Abstract
A method and system (100) is provided for continuous recycling of waste plastic feedstock into liquid fuels. The method includes sending the feedstock into a rotary retort vessel at an input end of the rotary retort vessel. The feedstock is received on either sides of a partition structure, wherein the partition structure connects the input end of the rotary retort vessel to an output end of the rotary retort vessel. The feedstock is pyrolized in the rotary retort vessel, wherein the feedstock produces gaseous byproducts and non-gaseous byproducts. The byproducts are moved towards the output end of the rotary retort vessel, wherein the movement is facilitated by declination of the rotary retort vessel and the one or more partition structures. The non-gaseous byproducts are continuously removed from the rotary retort vessel.
