WIPO Patent Application WO/2014/125613

A1

[Problem] To provide a separation device and a separation method that exhibit high separation efficiency. [Solution] A separation device (1) is provided with a shredding unit (10) (a first shredding unit), a separation unit (20) (a first separation unit), a shredding unit (30) (a second shredding unit), and a separation unit (40) (a second separation unit). The shredding unit (10) shreds a paper diaper (an object to be processed) containing plastic (a first material) and a water-absorbent polymer (a second material) that is attached to the plastic. The paper diaper that has been shredded by the shredding unit (10) is accommodated in the separation unit (20) and the separation unit (20) separates the water-absorbent polymer that has passed through a hole (22a) from the paper diaper by rotating a drum (42). The shredding unit (30) shreds the paper diaper from which the water-absorbent polymer that passes through the hole (22a) has been separated by the separation unit (20). The paper diaper that has been shredded by the shredding unit (30) is accommodated in the separation unit (40) and the separation unit (40) separates the water-absorbent polymer that has passed through a hole (42a) from the paper diaper by rotating a drum (42).
