Process for recycling of liquid carton waste material or other similar waste material having fibrous, metal and plastics materials. The process includes introducing the waste material and a slushing liquid into a slushing apparatus and slushing of the waste material to thereby form defibrated fibrous material therein. The treated waste material is then separated into (i) a fiber suspension which includes the defibrated fibrous material, and (ii) a reject portion which includes the metal and plastics materials. The obtained fiber suspension is cleaned and the fibrous material therein is reclaimed for further use. The reject portion is introduced into a fluidized bed gasifier so as to gasify the plastics therein to produce a hydrocarbon product gas, which is thereafter separated from the metal material.

1. Process for recycling of liquid carton waste material or other similar waste material which includes fibrous, metal and plastics materials, the process comprising the steps of:(a) introducing the waste material and a slushing liquid into a slushing apparatus and slushing of the waste material to thereby form defibrated fibrous material therein, (b) separating the waste material treated in step (a) into (i) a fiber suspension which includes the defibrated fibrous material, and (ii) a reject portion which includes the metal and plastics materials, (c) cleaning the fiber suspension obtained in step (b)(i) and recovering the fibrous material therein for further use, (d) introducing the reject portion obtained from step (b)(ii) into a fluidized bed gasifier and gasifying the plastics therein to produce a hydrocarbon product gas, and (e) separating metal material from the hydrocarbon product gas produced in step (d).
