Abstract: A manufacturing apparatus is an apparatus for manufacturing a water absorption treatment material that is composed of a plurality of grains, and includes a granulation machine and a coating machine. The granulation machine granulates a granulation material and thereby forms a granule (core portion) that constitutes each of the grains The coating machine attaches a coating material that contains an adhesive material to a surface of the core portion formed by the granulation machine, and thereby forms a coating portion that covers the surface of the core portion. The granulation machine forms the core portion that has a through hole that extends through the core portion.

Abstract: An excrement treatment material includes a plurality of granules that absorb excrement. Each granule includes a granular core portion, and a coating portion. The core portion has a circular cross-section, and has a function of absorbing and retaining the excrement. The coating portion coats the core portion. The coating portion has a function of causing the plurality of granules, which have absorbed the excrement, to adhere to each other. In a cross-section of each granule that is in the same plane as the cross-section of the core portion, a thickness of the coating portion on one side of the core portion is smaller than a thickness of the coating portion on another side of the core portion.

Abstract: A toilet suppresses the escape of odor from an upper part of a box-shaped main body part into which urine is excreted and includes a shielding member. The main body part has a bottom surface part and a side surface part. The shielding member projects from the inner surface of the side surface part toward the inside of the main body part, and blocks odor from the urine from rising.

Abstract: A separation device includes a first shredding unit, a first separation unit, a second shredding unit, and a second separation unit.
