Abstract

This invention relates to a method of making a bio-based PET packaging and particularly to a method of producing a bio-based PET from at least one bio-based material comprising: a) forming at least one PET component from at least one bio-based material, wherein the at least one PET component is selected from a monoethylene glycol (“MEG”), a terephthalic acid (“TA”), and combinations thereof; (b) processing said bio-based PET component into a bio-based PET.

Claims

1. A method of making a bio-based polyethylene terephthalate (PET), comprising:

(a) forming at least one PET component from at least one bio-based material, wherein the at least one PET component is selected from a monoethylene glycol (“

MEG”

), a terephthalic acid (“

TA”

), and combinations thereof;

(b) processing said bio-based PET component into a bio-based PET.

2. The method of claim 1, wherein the method further comprises solid state polymerizing the bio-based PET to form a PET resin and processing the PET resin into a PET perform, a PET packaging, and combinations thereof.

3. The method of claim 2, wherein said bio-based PET packaging comprises an edible product and said edible product comprises an ingredient which is made from said bio-based material.

4. The method of claim 1, wherein the at least one PET component is produced from the bio-based material using methods of fast pyrolysis, acid hydrolysis, enzymatic hydrolysis, microbial degradation, mycological degradation, or hydrogenolysis.

5. The method of claim 1, wherein the method further comprises processing the bio-based PET to form a fiber or a filament.

6. A method of making a bio-based polyethylene terephthalate (PET), comprising (a) refining a sugarcane into a molasses and a sugar;

(b) fermenting the molasses to produce an ethanol;

(c) refining the ethanol into an ethylene; and

(d) refining the ethylene into a MEG, at least one polyethylene, and combinations thereof.

7. The method of claim 6, further comprising melt polymerizing the MEG with a TA to form a bio-based PET and processing said bio-based PET to a PET container.

8. The method of claim 7, further comprising fermenting the molasses to produce a carbon dioxide and using said carbon dioxide and said sugar as a beverage component for a beverage stored in said PET container.

9. The method of claim 7, further comprising processing the at least one polyethylene to form a closure for said PET container.

10. The method of claim 7, further comprising processing the at least one polyethylene to form a PET secondary packaging for said PET container.

11. The method of claim 6, further comprising processing the at least one polyethylene into a PET packaging, wherein the at least one polyethylene is selected from a low-density polyethylene (“

LDPE”

), a high-density polyethylene (“

HDPE”

), a linear low density polyethylene (“

LLDPE”

), ultra-high molecular weight polyethylene (“

UHMWPE”

) and combinations thereof.

12. A method of making a bio-based polyethylene terephthalate (PET), comprising (a) solubilizing the corn starch 202 to form a starch solution;

(b) heating said starch solution in hydrogen steam catalyst to produce a mixture of glycols, wherein said mixture of glycols comprises ethylene glycol;

(c) purifying said mixture of glycols to form a MEG; and

(d) melt polymerizing said MEG with a TA to form a bio-based PET.

13. A method of making a bio-based polyethylene terephthalate (PET), comprising:

(a) extracting a peel from a fruit;

(b) extracting at least one peel component from said peel, wherein the at least one peel component is selected from limonene, sugar, a starch, a cellulose, and combinations thereof;

(c) refining the at least one peel component into at least one PET component, wherein the at least one PET component is selected from a MEG, a TA, and combinations thereof; and

(d) melt polymerizing the at least one PET component to form a bio-based PET.

14. The method of claim 13, wherein the fruit is selected from is selected from oranges, lemons, limes, grapefruits, tangerines, coconuts, and combinations thereof.

15. The method of claim 13, further comprising extracting a juice from said fruit, processing said Juice to form a beverage.

16. The method of claim 15, further comprising extracting a pulp from said fruit and dosing said pulp into said juice or beverage.

17. The method of claims 15-16, further processing said bio-based PET to form a bio-based PET container and dispensing said beverage into said PET container.

18. A method of making a bio-based polyethylene terephthalate (PET), comprising (a) collecting an agricultural waste stream;

(b) refining the agricultural waste stream into a MEG; and

(c) melt polymerizing the MEG with a TA to form a bio-based PET.

19. A method of recycling a bio-based PET packaging comprising (a) processing a bio-based PET through a PET processing center to produce at least one recycled material selected from a PET chip, a recycled MEG, a recycled TA, and combinations thereof;

(b) separating the at least one recycled material into groups of PET chips, recycled MEG, and recycled TA.

20. The method of claim 19, wherein the at least one recycled material is a recycled MEG, the method further comprising said recycled MEG with a new bio-based MEG to form a combination MEG stream.

21. The method of claims 19-20, wherein the at least one recycled material is a recycled TA, the method further comprising said recycled TA with a new bio-based MEG to form a combination TA stream.

22. The method of claim 21, further comprising polymerizing the combination MEG stream and the combination TA stream to form a new bio-based PET.
