Abstract: The invention discloses a refuse compactor assembly for compacting refuse into a cubical open-topped refuse receptacle having an enclosure structure for slidably receiving the cubical refuse receptacle and retaining same within the compactor assembly by force of gravity alone by providing a downwardly rearwardly inclined refuse receptacle support surface in the interior of the refuse compactor assembly. The refuse placed into the refuse receptacle is compacted by a reciprocably operable ram member which is provided with a wedge like compactor surface in the shape of a prism or, alternatively, an inverted pyramid.
