Abstract: Discussed herein is a shelf assembly that allows efficient discharge and collection of fluids out of fluid containers. In embodiments, the shelf assembly includes one or more racks that allow for placement of fluid containers in an inverted position. The shelf assembly further includes a collecting tray adjacent to (e.g., below) each rack to collect the fluids dripping out of the racks. The collecting tray discharges the fluids from the tray to a discharge station via outlets and/or connecting spouts. The discharge station allows for collection of the discharged fluids and subsequent disposal of the discharge. Such disposal is in accordance with EPA or other local regulations.
