Abstract

A system and method for recycling non-reusable refrigerant transport containers. At least one intact refrigerant transport container is received into a sealed chamber. The refrigerant transport container is punctured to release residual refrigerant, which is removed and compressed. The container is shredded and/or compacted. A refrigerant transport container deposit program is provided, comprising: encoding a deposit container prior to use; receiving the encoded spent container and releasing the imposed deposit; automatically removing residual refrigerant from the spent container; and recycling materials from the refrigerant transport container. A database storing a record relating to the encoded refrigerant transport containers may be employed for tracking.

Claims (32)

1. A system for implementing a refrigerant transport container deposit program, comprising:

an encoded refrigerant transport container, having a residual refrigerant content;

a database storing a record relating to the encoded refrigerant transport container;

a recycling machine, configured to automatically remove residual refrigerant from the encoded refrigerant transport container; and

a control, configured to update the database record based on at least the automatic removal.

2. The system according to claim 1 , further comprising a sensor configured to determine a type of refrigerant content of the encoded refrigerant transport container.

3. The system according to claim 1 , further comprising an scanner read a machine readable code associated with the encoded refrigerant transport container, to automatically determine a type of refrigerant content of the encoded refrigerant transport container.

4. The system according to claim 1 , further comprising a system to selectively route residual refrigerant content after removal from the encoded refrigerant transport container to a storage vessel in dependence on a type of residual refrigerant content.

5. The system according to claim 4 , further comprising a sensor configured to determine a purity of the residual refrigerant content, the system selectively routing the residual refrigerant content in dependence on the determined purity.

6. The system according to claim 1 , further comprising a bar code reader configured to read a bar code on the encoded refrigerant transport container.

7. A method for implementing a refrigerant transport container deposit program, comprising:

encoding a refrigerant transport container prior to use;

receiving and identifying the encoded refrigerant transport container at a recycling facility;

automatically recovering refrigerant within the encoded refrigerant transport container; and

crediting an account in a database dependent on the identity of the encoded refrigerant transport container and the automatic recovering.

8. The method according to claim 7 , further comprising determining a type of refrigerant recovered from the encoded refrigerant transport container.

9. The method according to claim 7 , further comprising reading a machine readable code associated with the encoded refrigerant transport container, to automatically determine a type of refrigerant within the encoded refrigerant transport container.

10. The method according to claim 7 , further comprising selectively routing recovered refrigerant from the encoded refrigerant transport container to a storage vessel in dependence on a type of recovered refrigerant.

11. The method according to claim 7 , further comprising determining a purity of the recovered refrigerant, and selectively routing the recovered refrigerant in dependence on the determined purity.

12. The method according to claim 1 , further reading a bar code encoding on the encoded refrigerant transport container.

13. A method for implementing a refrigerant transport container deposit program, comprising:

receiving an encoded refrigerant transport container, having a residual refrigerant content;

storing a record relating to the encoded refrigerant transport container in a database;

automatically removing residual refrigerant from the encoded refrigerant transport container in a recycling machine; and

updating the record in the database based on at least the automatically removing and an identification of the encoded refrigerant transport container.

14. The method according to claim 13 , further comprising determining a type of refrigerant content of the encoded refrigerant transport container.

15. The method according to claim 13 , further comprising reading a machine readable code associated with the encoded refrigerant transport container, to automatically determine a type of refrigerant content of the encoded refrigerant transport container.

16. The method according to claim 13 , further comprising selectively routing residual refrigerant content after removal from the refrigerant transport container to a storage vessel in dependence on a type of residual refrigerant content.

17. The method according to claim 16 , further comprising determining a purity of the residual refrigerant content, and selectively routing the residual refrigerant content in dependence on the determined purity.

18. The method according to claim 13 , further comprising reading a bar code on the encoded refrigerant transport container.

19. The method according to claim 13 , further comprising shredding the encoded refrigerant transport container.

20. The method according to claim 13 , further comprising puncturing the encoded refrigerant transport container to access the residual refrigerant content.
