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.
Claims22
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.
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.
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.
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.
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.
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.
