Polyethylene Furanoate (PEF): 100% Biobased Polymer to Compete with PET
In our July 9, 2012 post we discussed the initiative driven by Coca Cola to develop bio-based plastics for beverage containers. The first phase of this massive project has resulted in the Plant BottleTM which is made using bio-PET where the ethylene glycol starting monomer is made from renewable sources. The Plant Bottle contains approximately 30% bio-based carbon. But the project doesn’t stop there. Coca Cola has established three R&D partners (Virent, Gevo, and Avantium) to drive to a 100% biobased PlantBottle.TM As you recall, the Plant BottleTM used bio-based ethyleye glycol (EG) to make PET. The next piece of the puzzle is to find a synthetic route to bio-based terephthalic acid (PTA). The Virent approach uses soluble carbohydrate starting materials and the Gevo approach uses fermentable sugars to produce bio-terephthalic acid (bio-PTA). The Avantium YXY approach uses C6 sugars to produce furanics, then furandicarboxylic acid , which when polymerized with bio-EG will form bio PEF, a totally new, 100% biobased polymer. YXY is a trademark of Avantium (www.avantium.com
