Abstract
Waste material is encapsulated by charging into a container which is then closed by a cover (11) having filling and vent port means sealed temporarily by a diaphragm (13), such as a metal foil. A nozzle device (20) makes push-fit connections with the port means and ruptures the diaphragm in making the connections. Solidifiable medium is then introduced through the nozzle device and filling port while displaced atmosphere escapes through the vent.
