  • Patent number: 9650488
    Abstract: The present invention relates to a method for removing water from swollen superabsorbent polymers in a gel state, and a method for recycling sanitary absorbent articles using the same. According to the method of the present invention, water is removed from swollen superabsorbent polymers by immersing swollen superabsorbent polymers in a gel state into a composition wherein sea water that is readily available and calcium chloride that is readily available at low cost are mixed for a specified period of time. The method makes it possible to easily and economically remove water from swollen SAPs in a gel state. Thus, the method provides an economical and environmentally-friendly means for recycling sanitary absorbent articles comprising an absorbent that consists of SAP and cellulose pulp, after being used for absorbing human waste.
