Abstract

A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.

Claims (38)

1. A degradable containment comprising:

an outer structural layer defining a containment cavity and constructed of a pulp material;

a central carrier layer underlying the outer structural layer and constructed of a biopolymer, wherein the biopolymer comprises lignin; and

an interior nanomaterial layer constructed of a nanomaterial of hydrophobic nanoparticles, wherein the outer structural layer comprises a plurality of parts adhered by the central carrier layer and/or the interior nanomaterial layer and wherein the central carrier layer and/or the interior nanomaterial layer extend from a cavity of the containment to cover a portion or the entire exterior surface of the containment.

2. The degradable containment of claim 1 , wherein the pulp material includes at least one of the following; an organic product or an organic-based product.

3. The degradable containment of claim 1 , wherein the biopolymer further comprises polybutylene succinate.

4. The degradable containment of claim 3 , wherein the biopolymer has been dispersed in a solvent, the solvent including dichloromethane, dichlorodimethylsilane, hydrofluoroether, or a mixture of two or more thereof.

5. The degradable containment of claim 1 , wherein the nanomaterial includes at least one of the following: silicon dioxide and zinc oxide.

6. The degradable containment of claim 1 , wherein

the biopolymer includes at least two of polyhydroxyalkanoate, polybutylene succinate, or lignin;

the biopolymer has been dispersed in a solvent, the solvent including dichloromethane, dichlorodimethylsilane, hydrofluoroether, or a mixture of two or more thereof; and

the nanomaterial includes at least one of silicon dioxide and zinc oxide.

7. A degradable containment comprising:

an outer structural layer defining a containment cavity and constructed of a pulp material including at least one of the following: an organic product or an organic-based product;

a central carrier layer underlying the outer structural layer and constructed of a biopolymer including lignin; and

an interior nanomaterial layer underlying the central carrier layer and constructed of a nanomaterial of at least one of silicon dioxide and zinc oxide and including hydrophobic nanoparticles, wherein the hydrophobic nanoparticles increase gas barrier properties, and further wherein the outer structural layer comprises a plurality of parts adhered by the central carrier layer and/or the interior nanomaterial layer and wherein the central carrier layer and/or the interior nanomaterial layer extend from a cavity of the containment to cover a portion or the entire exterior surface of the containment.

8. The degradable containment of claim 7 , wherein the central carrier layer is applied directly to an interior surface of the outer structural layer and the interior nanomaterial layer is applied directly to an interior surface of the central carrier layer.

9. The degradable containment of claim 7 , wherein the central carrier layer and the interior nanomaterial layer are included in a combined layer applied directly to an interior surface of the outer structural layer.

10. The degradable containment of claim 9 , wherein the biopolymer has been dispersed in a solvent, the solvent including dichloromethane, dichlorodimethylsilane, hydrofluoroether, or a mixture of two or more thereof.

11. The degradable containment of claim 7 , wherein each of the plurality of parts includes at least one flange, the at least one flange from one of the plurality of parts aligning with the at least one flange from the other of the plurality of parts to seal the outer structural layer, the central carrier layer, and the interior nanomaterial layer together.

12. The degradable containment of claim 11 , wherein at least one of the central carrier layer and the interior nanomaterial layer extends onto the at least one flange of each of the plurality of parts and acts as an adhesive to seal the outer structural layer, the central carrier layer, and the interior nanomaterial layer together.

13. The degradable containment of claim 7 , wherein the central carrier layer and the interior nanomaterial layer extend from a cavity of the degradable containment, wrap around the outer structural layer at a lid receiving portion of the degradable containment, and continue on to cover at least a portion of an exterior surface of the outer structural layer.

14. A degradable containment comprising:

an outer structural layer defining a containment cavity and constructed of a pulp material including at least one of the following: an organic product or an organic-based product;

a central carrier layer underlying the outer structural layer and constructed of a biopolymer including lignin;

an interior nanomaterial layer underlying the central carrier layer and constructed of a nanomaterial including at least one of silicon dioxide and zinc oxide and including hydrophobic nanoparticles, wherein the outer structural layer comprises a plurality of parts adhered by the central carrier layer and/or the interior nanomaterial layer and wherein the central carrier layer and/or the interior nanomaterial layer extend from a cavity of the containment to cover a portion or the entire exterior surface of the containment; and

a modular containment neck secured in a top portion of the degradable containment.

15. The degradable containment of claim 14 , wherein the modular containment neck includes polypropylene, high density polyethylene, a biodegradable polymer, a biodegradable non-polymer, polypropylene, high density polyethylene, biopolymer or a mixture thereof.

16. The degradable containment of claim 14 , wherein the modular containment neck includes at least one tab configured to secure the modular containment neck in the top portion of the degradable containment.

17. The degradable containment of claim 14 , wherein the modular containment neck includes a screw-top configured to form a seal between the degradable containment and the modular containment neck.

18. The degradable containment of claim 14 , wherein the modular containment neck includes a securing flange configured to secure the modular containment neck in the top portion of the degradable containment.

19. The degradable containment of claim 14 , wherein the degradable containment further includes a lid securable to the modular containment neck.

20. The degradable containment of claim 1 , wherein the nanomaterial consists of hydrophobic nanomaterials.

21. The degradable containment of claim 1 , wherein the outer structural layer, the central carrier layer, and the interior nanomaterial layer are all biodegradable.

22. The degradable containment of claim 1 , wherein the interior nanomaterial layer degrades at a slower rate than the central carrier layer.

23. The degradable containment of claim 1 , wherein the biopolymer further include polyhydroxyalkanoate (PHA), lignin polybutylsuccinate (PBS), or PHA, PBS, and lignin.

24. The degradable containment of claim 1 , wherein the interior nanomaterial layer underlies the central carrier layer.

25. The degradable containment of claim 1 , wherein the central carrier layer underlies the interior nanomaterial layer.
