A container crusher, whereby a container is crushed from top to bottom into a compact neat form, to save extra space in the refuse bin or to save for recycling. The crusher has a central aperture or recess with cut out grooves for containers with handles. Surrounding the central aperture or recess is a concave area which rests or fits onto the container just below its neck. There is provided a separate insert for smaller sized containers, which slots into the central aperture or recess. At each end of the crusher are hand grips. To crush the container the crusher is placed onto the container and the cap is removed. With both hands, one at each end of the grips, pressure is applied downwards until the container is compressed.
