Abstract: A kitchen garbage treatment material absorbs moisture contained in kitchen garbage, and is constituted by grains. The grains contain a water-absorbent material. The water-absorbent material is constituted by at least one of fluff pulp and water-absorbent polymer that have been obtained by separating plastic from a sanitary product that contains the plastic, the fluff pulp, and the water-absorbent polymer.

Abstract: The manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die and a roller. A through hole that allows the granulation material to pass therethrough is formed in the die. The roller pushes the granulation material into the through hole while rolling on the surface of the die. In the granulation step, low-speed pushing in which the granulation material is pushed while the roller rolls at a first speed, and high-speed pushing in which the granulation material is pushed while the roller rolls at a second speed that is higher than the first speed are executed.

Abstract: Provided is a water absorption treatment material and a method for manufacturing the same, according to which a clump can be formed after use without incurring a decrease in water absorptivity. A water absorption treatment material includes a granular core portion and an embedded portion. A recessed portion is formed on the surface of the granular core portion. The embedded portion is provided in the recessed portion of the granular core portion. The embedded portion contains an adhesive material.

Abstract: An excrement treatment material includes a plurality of granules, and a packaging bag. The granules are granules for treating excrement. The plurality of granules are accommodated in the packaging bag. A partition member is provided in the packaging bag. The partition member partitions the interior of the packaging bag into a first space and a second space, and has a hole that does not allow the granules to pass through. The plurality of granules are accommodated, among the first space and the second space, only in the first space.
