In order to recover the various components of multiple layer materials, a method uses a refiner or disperser including mutually opposing rotating discs having material engaging surfaces or elements such as teeth. The method includes: adjusting a gap between the discs so that a material is subjected to a shear force that mutually separates its material layers in the form of pieces or fragments in the absence of any substantial disintegration of the layers; pumping the separated pieces of the various layers together with a supplied suspension liquid to a separator; and, separating readily pulped or slushed pieces of the material suspended in the suspension liquid from pieces of the suspended material that are not readily pulped or slushed. The pumping of the separated pieces and suspension liquid to the separator can be via a collection vessel.
