ABSTRACT:
A component recovery process to recover one or more of the constituent components of a feed material. In one embodiment, the process is a carpet recycling process, the feed material being carpet, and the constituent components being fiber, filler and adhesive. The process can refine the polypropylene backing polymer and face fibers of post industrial edge trim selvage, whole carpet construction post industrial scraps and pieces, as well as whole carpet post consumer scraps and pieces and in particular mixtures there of. The process beneficially uses land filled edge trim and pre land filled selvage, whole carpet construction scraps and whole carpet post consumer scraps and mixtures there of for component purification.
