Abstract:
1. A waste compaction system comprising: a body defining a waste-receiving receptacle having a perimeter defining an open top end, at least a bottom wall of the receptacle being vertically movable; a driving system operatively connected to the bottom wall for vertically moving the bottom wall to produce, when being displaced upwards, a corresponding upwardly directed compaction force on waste within the receptacle; an iris-type closure mechanism extending over the open top end and the iris-type closure mechanism is configured for displacement between an open position, where the closure mechanism surround an opening aligned with the open top end without obstructing access to the open top end, and a closed position, where a diameter of the opening is substantially reduced without the opening being completely closed; and wherein with the closure mechanism in the closed position, the driving system displaces the bottom wall upward to compact the waste contained within the receptacle against the closure mechanism.
