waste material according to the present invention will be described hereinbelow the compacted mass extruded from the compacting apparatus is shaped as it passes through the waste outlet 1c and is forced into the outlet nozzle 9 while it is gradually being cooled if the outlet nozzle 9 were too short the compressive force imposed on the extruded mass would be released due to the residual heat and the extruded mass would tend to be expanded at the outlet of the outlet nozzle 9 conversely if the outlet nozzle 9 were too long the apparatus would not be made compact in size and the extruded mass would be subjected to a greater resistance in the outlet nozzle 9 thus requiring an increased amount of power from the motor 6 since the extruded mass produced by compacting the solid waste material 2 is highly viscous a suitable cutting means is required to cut the extruded mass off the outlet of the compacting apparatus the cutting means may comprise a mechanical cutter or saw which however is not preferred because of its complex construction in the event that the waste material is radioactive radioactive particles would be produced if the extruded mass were cut off by the mechanical cutting means the aforesaid problems can be solved by the method and facility for producing a solid mass associated with the compacting apparatus the method and facility for producing a solid mass will be described with reference to fig5 through 8 as illustrated in fig5 through 7 the facility for producing a solid mass from a solid waste material includes a shaping tube 20 into which an extruded mass discharged from the compacting apparatus is forced the shaping tube 20 having a flanged end 20a and a tube closing assembly 21 for.
