Method to prepare feed bodies from waste material

Abstract

The present invention relates to a method to produce feed bodies, which are capable of providing free flowing granules and/or powder suitable for firing in an industrial furnace at one or multiple burners, the method comprising the following steps: (i) providing waste material comprising one or more thermoplastic material(s) of more than 40%, based on the total dry weight of the waste and one or more cellulosic material(s) of more than 30%, based on the total dry weight of the waste; (ii) processing the waste material in an extruder, which extruder is equipped with transport, kneading and heating elements such that the waste material is mixed and thermoplastic material is molten; (iii) wherein the material reaches a temperature of between about 110 and 200° C., for more than about 2 sec before cooling; (iv) pressing the processed waste material through a die with holes between 2-200 mm, and providing feed bodies with a thickness between about 2-200 mm, and a length of between about 2-500 mm.
