A waste container includes a top chamber, a base chamber, upper and lower lids, and a drive mechanism mechanically coupling the lower lid with the upper lid. The upper lid is disposed on the top chamber and moves between a closed position covering a first opening and an open position exposing the first opening. The lower lid is disposed on the base chamber and moves between a closed position covering a second opening and an open position exposing the second opening. The drive mechanism is actuated so as to move the lower lid to the open position when the upper lid moves to the closed position from the open position. The lower lid returns to the closed position when the upper lid is in the closed position.
