ABSTRACT:
A method of simultaneously recycling a plurality of used oil filters involves placing a plurality of the filters into a rectangular compartment having a top, opposite sides, a bottom, and first and second ends. Pressure is exerted on the oil filters in a first longitudinal direction, and a second compressive pressure is imposed on the filters in a second longitudinal direction at a substantial right angle with respect to the first longitudinal direction. The first and second pressures are sufficient to compress the air filters to a substantial self-contained rectangular block. This method produces a self-contained block wherein 90% to 95% of the residual oil in the filters is removed.
