A destructive device, wherein treated material ( 1 ) including a foam body is pre-compressed in thickness direction and fed to the opposed part of a pair of compression rolls ( 21, 22 ), partition walls forming independent air bubbles in the foam body is destructed by the compression rolls ( 21, 22 ) and foam gas is arrested into a cover ( 3 ) installed on the outlet side of the compression rolls ( 21, 22 ), the foam gas is liquefied and separated by a cooling and liquefying device ( 6 ) through a cooling device ( 15 ) after pressurized, together with medium gas ( 41 ) for collection, by a pressurizing device ( 5 ), and the medium gas for collection from which the foam gas is separated is returned into the cover ( 3 ), whereby, since the foam gas is liquefied and separated in pressurized state by the cooling and liquefying device ( 6 ) by arresting the foam gas in high density inside the cover ( 3 ), the device can be remarkably downsized and simplified, and a device cost and an operation cost can also be remarkably reduced.
