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.
