A device for compacting trash and the like comprises a bin having an open top through which the material to be compacted can be passed and walls which define a volume into which the material is deposited. A horizontally disposed, rectangular pressure plate for compacting the material is horizontally driven from a zone horizontally removed from the open top into a region above the volume. The pressure plate is vertically driven between the region and the volume to compact the material in the bin and is returned to the region. The plate is vertically driven by first and second vertical pistons that are respectively positioned to drivingly engage opposite, straight, parallel edges of the pressure plate. The pistons are separately driven by fluid pressure until the fluid pressure acting on one of the pistons reaches a predetermined value. The pressure plate is horizontally driven from a first pair of stationary channels, at the zone, into a second pair of channels, at the region; the second pair of channels is verticaly driven by the pistons. The entire sequence is normally automatic and is initiated in response to an operator activating a push-button. When it is desired to remove the compacted material from the bin, the automatic sequence is altered so that the pressure plate is stopped when the predetermined pressure is reached. With the pressure plate in the compacting position, a door is opened and baling wire is inserted into aligned longitudinal grooves in a floor of the bin, in the pressure plate, and in a wall of the bin opposite from the door. To facilitate removal of a wrapped bale, a door is provided on each of a pair of adjacent bin walls that are substantially at right angles to each other. The doors have abutting, latched edges, when closed.
