Document Type and Number:
Japanese Patent JP2002522644
Kind Code:
A
Abstract:
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.
