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.

The first and second inner box members are arranged in the outer box member such that the first sidewall portions thereof respectively face the first and second sidewall portions of the outer box member. The inner box members are spaced apart from each other in the outer box member, and excrement is collected in a space formed therebetween.

Abstract: A water absorbing material contains a water-absorbent material consisting of at least one of plastic and fluff pulp that are obtained by separating a water-absorbent polymer from a sanitary article containing the plastic, the fluff pulp and the water-absorbent polymer. The weight ratio of the water-absorbent polymer adhering to the water-absorbent material with respect to the water-absorbent material is 3% or less.

Abstract: A ready-to-assemble house having sufficient strength includes a column member and wall members that are made of cardboard or heavy paper. A side end portion of the wall member is fixed to the column member. A side end portion of the wall member is fixed to a side end portion of the wall member. A side end portion of the wall member is fixed to a side end portion of the wall member. A side end portion and a side end portion of the wall member are respectively fixed to a side end portion of the wall member and the side end portion of the wall member. The column member is configured to become shaped as a rectangular column by being folded along folding lines.

Abstract: A water absorbing material which can reduce burden on the environment in disposal and can be manufactured at low cost, and a manufacturing method thereof are provided. The water absorbing material contains paper obtained by separating polyvinyl chloride from vinyl chloride wallpaper as a raw material.

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.

Abstract: Provided are a separation device and a separation method with which plastic and aluminum can be separated. A separation device includes a heating unit, a container, and a pressing member. The heating unit heats a processing target containing aluminum and one or more types of plastic to a first temperature. 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 is for accommodating the processing target heated by the heating unit to the first temperature. The pressing member has a hole portion allowing the plastic melted by the heating unit to pass through, and separates aluminum and the plastic by pressing the processing target accommodated in the container.
