A method of processing bagged refuse includes pneumatically conveying filled refuse bags along a conduit using an airflow and opening the bags during the pneumatic conveyance. An apparatus for carrying out the method includes a conduit configured to pass an airflow to pneumatically convey bagged refuse along the conduit and a bag opening structure arranged to open the refuse bags during pneumatic conveyance along the conduit. The open bagged refuse is sorted into fractions using the airflow by passing the refuse across an opening through which the airflow continues. A wall is arranged in the path of travel of the pneumatically conveyed refuse to disaggregate the refuse by impacting the refuse against the wall. The wall is arranged vertically and at least partially defines an opening through which the air stream continues such that a fraction of the refuse falling across the opening is conveyed through the opening.
