Abstract:
Provided is a method for efficiently recovering pulp fiber from used hygiene products that include pulp fiber and a polymer absorbent. This method is characterized by including a step for introducing the used hygiene product into a treatment tank in which an aqueous solution with ozone dissolved therein has been introduced, and a step for treating the used hygiene product while infusing water into the treatment tank at a first flow rate, extracting the aqueous solution from the treatment tank at a second flow rate and introducing a gas containing ozone into the aqueous solution in the treatment tank, thereby decomposing the polymer absorbent, lowering the molecular weight thereof, and making the same dissolvable.

Claim (Index 6):
The method according to  claim 1 , wherein\n a product of an ozone concentration (mass ppm) of the aqueous solution and a time (minute) of the step of treating the used hygiene product, decomposing the polymer absorbent material, lowering the molecular weight of the polymer absorbent material and making the polymer absorbent material dissolvable is 100 to 6000 mass ppm\u00b7minute.
