Embodiment

[0021] Methods of Producing Bio-Based PET: Sugarcane

[0022] A typical deficiency of sugarcane refining today is that after the cane has been refined into sugar and molasses, the remaining cane husk (or sometimes called bagasse) is usually discarded in the garbage or burned as fuel or used as animal feed. Bagasse is rich in cellulose, hemicellulose and lignin, but has little food value. Finding alternative ways to use leftover bagasse to produce bio-based PET would reduce waste. In the following process, sugar beets can also be used instead of sugar cane.

[0023] refer to figure 1 , a specific embodiment of the invention comprises a method of producing bio-based PET from sugar comprising the steps of: a) refining sugar cane 102 into molasses 104 and sugar 106; b) fermenting said molasses 104 to produce ethanol 108; c) refining the ethanol to ethylene 110; refining the ethylene 110 to MEG 112; and melt polymerizing the MEG 112 and the TA 128 to form bio-based PET 120.

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.
