The present invention is directed to a container for the collection and temporary storage of amalgams and other mercury wastes. The container can include a hollow body with air-tight lid, and one or more mercury sorbents contained in a filter bag. The filter bag covers the inside surface of the hollow body and has holes that allow air exchange between the air in the hollow body and the sorbents. As air exchange occurs, mercury vapors released from dental wastes binds to the mercury binding materials. A self-closing door was made on the lid, which automatically closes after each waste disposal.
