Abstract
A press (10) for waste has a chamber that is enclosed in part by a sliding door (20). The door has an extrusion section (22) and an expulsion section (24). The extrusion section encloses the chamber while waste (18) is compressed in the chamber to extrude a wet fraction (32) of the waste. The expulsion section abuts the chamber when a remaining dry fraction (40) of the waste expelled. Preferably, the expulsion section is above the extrusion section. Various details of the door account for leakage of wet fraction waste between the chamber and the door.
