A method for manufacturing a water absorption treatment material made of a plurality of grains includes a preparing step, a pulverizing step, a core portion forming step, and a coating portion forming step. The preparing step is a step of preparing a paper powder to which water-absorbent polymers adhere, the paper powder being derived from a sanitary product. The pulverizing step is a step of pulverizing remaining polymers using a pulverizer. The core portion forming step is a step of forming a core portion constituting each of the grains The coating portion forming step is a step of forming a coating portion so as to cover the core portion, the coating portion containing the paper powder, and the remaining polymers pulverized in the pulverizing step. In the pulverizing step, the remaining polymers left in a state of adhering to the paper powder are subjected to the pulverizer.
