A specialized crusher has an upright compartment sized to receive an individual oil filter resting on a grate at the bottom. A crusher plate above the filter is guided for vertical sliding movement in the compartment and is moved up and down by a hydraulic jack. Downward movement of the crusher plate collapses the oil filter casing to compact condition and oil contained in it passes through the bottom grate into a spout leading to a receptacle. When a desired pressure has been reached, the jack automatically lifts the crusher plate and the collapsed casing can be removed for salvaging. All components of the apparatus are incorporated in a compact cabinet which can have a bottom drawer for the oil receptacle and a bin in which the collapsed casings can be collected.
