Degradation process of mixtures of waste plastic polymeric material containing halogenated polymers comprising the steps of: a) melting said plastic material at T>200°C and ≤220°C; b) dehalogenating the molten mixture by production of gaseous halogenidric acid from the previous step (a) at T between 300 and 410°C, preferably between 320 and 380°C: c) degrading the dehalogenated mixture from step (b) at a temperature between 410°C and 500°C and with retention times >5 minutes and ≤ 20 minutes, wherein the reaction products mainly comprise low boiling hydrocarbons, and in lesser extent hydrogen, naphtha, gasoline, jet fuel, diesel, heavy oils, residues.
