In 2009, the Coca-Cola Company introduced PlantBottle TM , a technology for manufacturing poly(ethylene terephthalate) (PET) plastic bottles with partially plant-based materials. In 2015, the company made further progress by announcing their capability of producing bottles entirely from renewable resources. This is just one example of numerous efforts devoted to developing bio-based polymers in recent years. PET, the most common polyester, can be manufactured by polymerizing ethylene glycol (EG) with terephthalic acid (TPA) via esterification (Scheme 1).
