A bindery compactor and/or baler receives and compacts or bales simultaneously large particulate paper waste and pneumatically conveyed fine paper waste. The compactor and/or baler operate with a platen cycling within a chute. The platen is normally forward in the compacting position with a sealing plate attached to the platen extending to close the top of the chute and form the bottom of two waste paper receiving bins. A first of these paper waste-receiving bins is for large particulate paper waste loaded from a cart dumper or conveyor. A second of these waste-receiving bins is for pneumatically transported fine paper waste from a cyclone separator. In both bins, accumulation of paper waste occurs to a height where an electric eye triggers cycling of the compactor only when a sufficient volume of material is present for compaction and an excess volume is present for preventing pneumatically induced escape of material. When cycling is triggered, the compactor platen retracts from extension to the chute withdrawing the sealing plate and allowing the stored paper waste from either bin to fall into the chute ahead of the retracting platen. Upon reaching full retraction, the platen reverses direction to compact all paper waste falling from either bin in the chute. In all cases, blowing by or escape of fine particles is prevented by remaining waste in either the bin receiving fine paper particles or the bin receiving the large paper particles.
