  • Patent number: 10493661
    Abstract: Improving the recovery from recycling a disposable absorbent article including superabsorbent polymer includes separating the article into a mixed polymeric material/cellulosic fiber stream and a superabsorbent polymer/fibers stream; and processing the mixed polymeric material/cellulosic fiber stream using an enzyme to release the cellulosic fibers from the polymeric materials.
