Abstract: A portable compactor for landscape waste formed as a generally rectangular box, extending from a gate at a front end to a closed second end. An opening in top of the box allows waste to be placed in an internal compaction chamber and a compaction plate disposed inside the box moves on parallel threaded drive rods extending along either side of the compactor to compact inserted material against the gate. Following compaction, the plate may be reversed to move away from the gate to provide additional space for insertion of waste. When full, the gate may be opened and the plate advanced to push waste out of the compaction chamber where it can be further used, disposed of or bagged for conversion to silage. The system may be sized to allow for installation in the bed of a pick-up truck, or on a small flatbed or trailer.
