The apparatus has a hopper which is placed below the injection nozzle of an injection molding machine. Purge is released from the injection nozzle and falls into a hopper located on the apparatus. From the hopper the purge is drawn downward by two coacting compression rollers which have the dual function of compressing and forming the purge into a recyclable form. After compression and forming the purge is available for storage or reuse.
