Abstract: Disclosed herein is a method for co-pyrolysis of a polyolefin and a rubber containing material comprising: operating at least a pyrolysis stage of a pyrolysis reactor at an operating temperature at or above the temperature at which pyrolysis of both the polyolefin and the rubber containing material commences and up to about 600° C. under a substantially inert atmosphere; feeding a mixture comprising the polyolefin and the rubber containing material into the pyrolysis reactor; co-pyrolysing the mixture in the pyrolysis reactor to produce a pyrolysis gas comprising volatile pyrolysis products of the polyolefin and the rubber, wherein the volatile pyrolysis product of the olefin comprises at least a short chain olefin and the volatile product of the rubber comprises at least a diene; and facilitating a gas phase reaction between the short chain olefin and the diene to produce a volatile gas comprising single-ring aromatic hydrocarbons.
