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. The method can also include shredding the disposable absorbent article; re-pulping the shredded disposable absorbent article; and dehydrating the superabsorbent polymer, wherein dehydrating includes belching fluid from swollen superabsorbent polymers (SAPs) by immersing swollen SAP in a gel state into a composition for removing moisture, wherein seawater and 0.5 to 3% by weight of calcium chloride based on the weight of seawater are mixed for 10 minutes to 4 hours.
