摘要： Provided is a cellulose nanofiber manufacturing method which is less likely to cause concerns in terms of safety and the environment and by which a high-quality cellulose nanofiber can be manufactured. This manufacturing method is for manufacturing a cellulose nanofiber from a pulp fiber. The manufacturing method comprises: ozone treatment step S31 for performing an ozone treatment on a pulp fiber in a first aqueous solution; and defibration treatment step S32 for performing a physical defibration treatment on the ozone-treated pulp fiber in a second aqueous solution. In the manufacturing method the ozone treatment step and the defibration treatment step are continuously performed a plurality of times to form the cellulose nanofiber having a hemicellulose content of less than 8.0 mass% and a lignin content of at most 0.10 mass%.

摘要： The purpose of the present disclosure is to provide a method for regenerating a highly water-absorbing polymer that has been deactivated by an acid, the method enabling formation of a highly water-absorbing recycled polymer having predetermined water absorption properties. The regeneration method according to the present disclosure is configured as follows. This method regenerates a highly water-absorbing polymer that has been deactivated by an acid into a highly water-absorbing recycled polymer having predetermined water absorption properties. The method includes: a preparation step (S1) for preparing a highly water-absorbing polymer which has an acid group and which has been deactivated by an acid; a highly water-absorbing recycled polymer-forming step (S3) for adding an alkali metal ion source, which can supply an alkali metal ion, to a regeneration-use aqueous solution that contains the highly water-absorbing polymer that has been deactivated by an acid, and forming the highly water-absorbing recycled polymer in a wet state from the highly water-absorbing polymer that has been deactivated by the acid; and a drying step for drying the highly water-absorbing recycled polymer in a wet state and forming the highly water-absorbing recycled polymer having the predetermined water absorption properties.

摘要： Provided is a method for recycling a superabsorbent polymer derived from a used absorbent article, which is capable of suppressing a relative decrease in the absorption performance of the recycled superabsorbent polymer. The method for recycling a superabsorbent polymer derived from a used absorbent article comprises: an ozone treatment step (S31) of treating the superabsorbent polymer with ozone water after inactivating the superabsorbent polymer; a reactivation step (S32) of reactivating the ozone-water-treated superabsorbent polymer with an alkaline aqueous solution; and a surface treatment step (S40) of adding hydrophilic fine particles to the superabsorbent polymer reactivated with the alkaline aqueous solution and then drying.

摘要： Provided is a method for producing pulp fibers to be saccharified, whereby it becomes possible to reduce the amount of a highly water-absorbable polymer and therefore increase the collection efficiency in the production of a saccharified solution when pulp fibers for a saccharified liquid is produced from a dirty absorbent article. The method is a method for producing pulp fibers to be saccharified, from pulp fibers in a dirty absorbent article. The method includes: a solid-liquid separation step (S18) of crushing up a highly water-absorbable polymer while separating an inactivated aqueous solution containing pulp fibers and the highly water-absorbable polymer both separated from a dirty absorbent article into a solid material (98) containing the pulp fibers and the highly water-absorbable polymer and a liquid material (E) containing the highly water-absorbable polymer and the inactivated aqueous solution; and a removal step (S21) of washing away the remaining highly water-absorbable polymer by washing the separated solid pulp fibers in a solution or another means to produce pulp fibers to be saccharified.
