Abstract

A method and apparatus for disposing of waste in an aircraft. An apparatus comprises a receptacle system. The receptacle system is configured to hold the waste. The receptacle system is located in a space between a galley and a bulkhead of the aircraft.

First claim

What is claimed is:

1. An apparatus comprising:
a receptacle system configured to hold waste, wherein the receptacle system is located in a space between a galley and a bulkhead of an aircraft; and
a drawer system associated with a galley structure and in communication with the receptacle system and configured to receive the waste and move the waste into the receptacle system, wherein the drawer system comprises a compartment associated with the galley structure and having a first opening configured to receive the waste, a moveable barrier in a bottom of the compartment configured to move to expose a second opening such that the waste moves from the compartment through the second opening into the receptacle system, and an angled portion connected to the moveable barrier using a hinge such that the moveable barrier moves relative to the angled portion.

2. The apparatus of claim 1 , wherein the compartment is moveable within the galley structure between an open position and a closed position such that the waste is received in the compartment through the first opening when the compartment is in the open position and the waste moves through the second opening into the receptacle system when the compartment is in the closed position with the moveable barrier moving to expose the second opening.

3. The apparatus of claim 2 , wherein:
the angled portion in the compartment is configured to move the waste toward the moveable barrier such that the waste received in the compartment through the first opening is moved through the second opening into the receptacle system when the moveable barrier moves to expose the second opening.

4. The apparatus of claim 3 , wherein the moveable barrier comprises flexible tabs configured to be positioned above the receptacle system when the compartment is in the closed position.

5. The apparatus of claim 1 , wherein the receptacle system comprises:
a group of bins; and
a deflector associated with the group of bins and configured to direct the waste into the group of bins.

6. The apparatus of claim 1 , wherein the receptacle system is configured to be accessed using a group of doors located below the galley structure.

7. The apparatus of claim 1 , wherein the waste is selected from at least one of trash, recyclable materials, liquid waste, or hazardous materials.

8. The apparatus of claim 1 , wherein the bulkhead is an aft pressure bulkhead of a fuselage of the aircraft.

9. A method for disposing of waste in an aircraft, the method comprising:
receiving the waste through a first opening in a compartment associated with a galley structure; and
moving the waste from the compartment through a second opening into a receptacle system located in a space between a galley and a bulkhead of the aircraft using a drawer system in communication with the receptacle system by moving a moveable barrier in a bottom of the compartment to expose the second opening, wherein the drawer system comprises an angled portion connected to the moveable barrier using a hinge such that the moveable barrier moves relative to the angled portion.

10. The method of claim 9 further comprising:
moving the waste toward the moveable barrier using the angled portion in the compartment such that the waste received in the compartment through the first opening is moved into the receptacle system when the moveable barrier moves to expose the second opening.

11. The method of claim 10 further comprising:
moving the compartment within the galley structure between an open position and a closed position such that the waste is received in the compartment through the first opening when the compartment is in the open position and the waste moves through the second opening into the receptacle system when the compartment is in the closed position when the moveable barrier moves to expose the second opening.

12. The method of claim 9 further comprising:
directing the waste into a group of bins in the receptacle system using a deflector.

13. An aircraft comprising:
a galley in an aft section of a fuselage of the aircraft; and
a waste disposal system associated with the galley and comprising a receptacle system having a group of bins configured to hold waste and a drawer system associated with a galley structure and in communication with the receptacle system, wherein the receptacle system is located in a space between the galley and an aft pressure bulkhead of the fuselage of the aircraft, and wherein the drawer system comprises a compartment associated with the galley structure and having a first opening configured to receive the waste, a moveable barrier in a bottom of the compartment configured to move to expose a second opening such that the waste moves from the compartment through the second opening into the receptacle system, and an angled portion in the compartment connected to the moveable barrier using a hinge such that the moveable barrier moves relative to the angled portion and configured to move the waste toward the moveable barrier such that the waste received in the compartment through the first opening is moved through the second opening into the receptacle system when the moveable barrier moves to expose the second opening.

14. The aircraft of claim 13 , wherein the receptacle system comprises:
a deflector associated with the group of bins and configured to direct the waste into the group of bins.

15. The aircraft of claim 13 , wherein a first bin in the group of bins is configured to hold recyclable materials and a second bin in the group of bins is configured to hold trash.

16. The aircraft of claim 13 , further comprising:
a group of doors located below the galley structure and configured to open to provide access to the group of bins.
