摘要： A method of treating polymer absorbent of a used sanitary product including pulp fiber and the polymer absorbent, comprising the steps of making the polymer absorbent imbibe water in an amount equal to a weight of the polymer absorbent or more, making the polymer absorbent in a moisture-containing state come in contact with an ozone-containing gas, and decomposing, lowering molecularization, and solubilizing at least a portion of the polymer absorbent by the ozone-containing gas.

摘要： The present invention aims to develop a technique for efficiently preparing deinked pulp from prints made with UV-curable inks. According to the processes for preparing deinked pulp of the present invention, high quality deinked pulp can be obtained by performing the steps of: disintegrating printed waste paper containing UV prints in water to give a waste paper slurry; and applying a mechanical process to the waste paper slurry using a rotary disintegrator.
