PURPOSE: To always achieve sterilization, deodorization, and coagulation without increasing the volume of the waste in liquid form or in muddy form by adding the sterilizing component and deodorizing component into a highly water- absorptive resin.

CONSTITUTION: Na dichloroisocyanurate, bleaching powder, Na o- phenylphenolate, etc., as a sterilizing component are added into a highly water- absorptive resin, and a proper quantity of powder perfume as a deodorizing agent is added, and the resin is shaped into a powder or pellet form. This powder or pellet is fed into the waste in liquid form or muddy form, and kneaded, and then Na dichloroisocyanurate, etc., develop the sterilizing action, and the powder perfume develops the deodorizing action due to masking, and at the same time, the highly water-absorptive resin develops the coagulation action, and fluidity is suppressed, and scattering, etc., are prevented. Further, since sterilization, deodorization, and coagulation can be carried out in one time, easy use is enabled.
