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.

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.

The invention concerns a rotary machine (1) for sorting a mixture of wastes (2), said sorting machine (1) being characterized in that it comprises at least: a first trammel section (3), provided with a first separation wall (5) extending over a first length (L1) allowing separating the mixture of wastes (2) into a first fraction of wastes (13) getting through said first separation wall (5) and into a residual second fraction of wastes (14), and a second trammel section (4), provided with a second separation wall (6) extending over a second length (L2) smaller than the first length (L1), and allowing separating the residual second fraction of wastes (14) into a subfraction of small-sized wastes (15) getting through said second separation wall (6) and into a residual subfraction of large-sized wastes (16). Wastes sorting.

There as herein defined a pneumatic conveying system comprising a cyclonic feed apparatus. In particular, there is described a pneumatic conveying system comprising a vessel (e.g. a cyclonic separator) in combination with a sifting device (e.g. a centrifugal device) which is capable of separating pneumatically conveyed material into oversize powder discharge (e.g. waste material) and fine powder discharge (e.g. valuable product material).
