Process and system for reclaiming polymeric fibers (e.g., nylon) from post-consumer carpeting includes shredding the post-consumer carpeting into strips, dismantling the carpet strips to form a mixture of the fibers to be reclaimed and the backing material to be discarded, and then separating a substantial portion of the fibers from the backing material. Preferably, the carpet strips are dismantled by impacting the strips of carpeting against an anvil structure with hammer elements using, e.g., a hammermill. A secondary reclamation system is provided whereby the separated backing material which may contain some fibers bound thereto is subjected to secondary dismantling and separation operations. The fractions obtained from the primary and secondary separation operations containing predominantly the polymeric fibers may thus be combined so as to form a process discharge stream which can be pelletized and/or baled as desired.
