Abstract: A woven fabric includes a first constituent yarn having an optical fiber yarn and a non-light guiding yarn and a second constituent yarn having a non-light guiding yarn. The woven fabric has a first region in which the first and second constituent yarns are woven in one layer and a second region which is positioned adjacent to the first region and in which the first and second constituent yarns and are woven in two or more separable layers. The woven fabric has an optical fiber layer and a back protecting layer as the separable layers. The optical fiber layer is a layer formed of the optical fiber yarns. The back protecting layer is a layer in which the non-light guiding yarn of the first constituent yarn and the non-light guiding yarn of the second constituent yarn are woven. Further, the woven fabric can further comprise a front protecting layer.

Abstract: A separation device includes a first shredding unit, and a first separation unit. The first shredding unit shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second material) adhering to the plastic. The first separation unit has a first tubular portion, and a first beating member. The first separation unit separates the water-absorbent polymer passing through first holes from the disposable diaper by beating the disposable diaper with a plate surface of the first beating member with the first tubular portion being rotated in a state in which the disposable diaper shredded by the first shredding unit is accommodated therein.

Abstract: A separation device includes a first shredding unit, a first beating unit, and a first separation unit. The first shredding unit shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second material) adhering to the plastic. The first beating unit beats the disposable diaper shredded by the first shredding unit with a first beating member, thereby promoting dissociation of the water-absorbent polymer from the plastic. The first separation unit rotates a first tubular portion in a state in which the disposable diaper beaten by the first beating unit is accommodated therein, thereby separating the water-absorbent polymer passing through first holes from the disposable diaper.

Abstract: A water absorbing material that is suitable for being discarded by being flushed down a flush toilet is provided. The water absorbing material includes only an organic substance containing no nutrients.

Abstract: A box-shaped ready-to-assemble toilet is made of corrugated board or cardboard. The ready-to-assemble toilet includes first to fourth sidewall portions and a bottom portion. Each of the first to fourth sidewall portions includes an outer sidewall, an inner sidewall and a horizontal wall. The horizontal walls of the first and second sidewall portions overlap each other. The horizontal walls of the second and third sidewall portions overlap each other. The horizontal walls of the third and fourth sidewall portions overlap each other. The horizontal walls of the fourth and first sidewall portions overlap each other.

Abstract: A separation device includes a first shredding unit, a first separation unit, and a first air pipe. The first shredding unit shreds a processing target containing a first material and a second material. The first separation unit rotates a first tubular portion in a state in which the processing target shredded by the first shredding unit is accommodated therein, thereby separating the second material passing through first holes from the processing target. The first air pipe transfers the processing target shredded by the first shredding unit to the first separation unit with air pressure. The first air pipe has a first portion that extends in a first direction, and a second portion that is connected to the first portion on a downstream side of the first portion and that extends in a second direction substantially orthogonal to the first direction.

Abstract: Provided are a separation device and a separation method with which plastic and aluminum can be separated. A separation device includes a separation unit. The separation unit includes a container and a scoop-up member. A processing target containing aluminum and one or more types of plastic is heated to a first temperature in the separation unit. The first temperature is a temperature that is less than the melting point of aluminum and is greater than or equal to the melting point of at least one type of plastic. The container accommodates the processing target heated to the first temperature. The scoop-up member has a hole portion allowing melted plastic to pass through, and separates aluminum and the melted plastic by scooping up the processing target accommodated in the container.

Abstract: Provided are a separation method and a separation device used therein with which plastic and aluminum can be separated. The separation method includes a first heating step, and a first heat insulation step. In the first heating step, a processing target, which is accommodated in a container and contains aluminum and one or more types of plastic, is heated to a first temperature. The first temperature is a temperature that is less than the melting point of the aluminum and is greater than or equal to the melting point of at least one type of the plastic. Thus, the at least one type of plastic is melted. In the subsequent first heat insulation step, the processing target is kept at the first temperature. The heat insulation is continued until the aluminum is precipitated in the container and separated from the melted plastic.
