A method of recycling spent filter media is disclosed. The method can include providing a cloth, the cloth being spent polymer-base filter media, removing foreign solid particles from the cloth, washing the cloth, drying the cloth and processing the dried cloth to produce polymer-base particles that can be used to produce a component. The processing of the dried cloth can include densifying and/or granulating the dried cloth. In addition, the spent cloth can have been used as metal working filtration media and the foreign solid particles removed from the cloth using a brush. In some instances, the cloth is washed using a dry cleaning process and the granulating or densifying of the cloth produces particles that can be used in an injection molding machine.
