PROBLEM TO BE SOLVED: To regenerate and reuse used paper such as newspapers or magazines by melting and kneading a mixture of pulverized used paper obtained by grinding the used paper in the form of powder and a resin raw material, and extruding the mixture and further pelletizing it by an extruder. SOLUTION: Either of newspapers or magazines, or handbills or all kinds of used paper are fed into a hopper 6 provided in the cylinder 3 of an extruder 10, together with pulverized paper 21 obtained by grinding it previously using a grinder and a resin raw material 22. In addition, these materials are heated, melted and kneaded by a pair of screws 5 and a resin heater 9 in the cylinder 3 and at the same time, are sequentially transferred to a molding die 7 from the hopper 6 side. Further the mixture is extruded to the outside from the outlet of the molding die 7. In this case, the mixture is extruded in the form of a strand from the outlet which is of a holelike shape, and the extruded mixture is cut using the cutter of a granulator 25 to be set in the water. After that, the set granules are sent to another place to be dried and pelletized 26. Thus regenerate and reuse of used paper such as newspapers, magazines or handbills are made possible.
