Abstract: A method for producing a densified material includes: obtaining a film including at least one first layer of plastic material and one second layer with a composition distinct from the first layer, the first layer having a first melting temperature, or obtaining pieces of such a film; compressing the obtained film or the obtained pieces of film through at least one die of at least one extruder, and obtaining a profile of densified material, the extruder including at least one rotary endless screw pushing the obtained film or pieces of film along a screw axis; and optionally cutting the profile in order to obtain granules of densified material, the compression step being carried out at a maximum compression temperature for the obtained film or pieces of film, the maximum compression temperature being less than the first melting temperature. Also disclosed are installation and use of the densified material.
