Abstract: A compactor has a plunger housing with a door for insertion of waste. The plunger presses waste into a bag on a pallet within an enclosure with panels and a pair of panels in the form of doors at the rear. Side panels, are joined along their lower edges to a floor panel, the side panels supporting the end panels at vertical hinges. There is resilience due to the ability of the various panels to move, in which each side panel is cantilevered about the corner at which it is joined to the floor panel, and the end panels can rotate about the relevant vertical axis of the hinges. As the plunger presses axially to compact waste within a bag when the bag approaches being full.
