Abstract: The present invention is a manually operated trash compactor with a refuse container mounted on a mobile platform. The container has a first section fixed to the platform and a second section pivotally attached to the first section. A latch is mounted to the container to hold the container closed during compaction. A compaction plate is mounted to a rack gear and pinion gear assembly. The assembly is rotatable between a starting position, with the compaction plate disposed over the refuse container, and a position lateral to the container. A drive wheel is connected to the pinion gear to rotate the pinion gear to selectively adjust the rack gear and compaction plate into the container to compress refuse in the container lined with a trash bag. A compression spring is mounted on the rack gear to facilitate automated return of the compaction plate to its starting position. A tension adjuster is in contact with the rack gear to control the rate of return of the rack gear.
