Blow moulded polyethylene terephthalate (PET), polyester, Coca-Cola bottle made with renewable chemistry. Paraxylene was produced by Virent using their proprietary Bioforming process, which converts carbohydrates into hydrocarbons via catalytic conversion. Taiwan-based Far Eastern New Century then worked with Virent and Coca-Cola to convert the paraxylene into a renewable PET resin. Hydrocarbons made with the Virent Bioforming catalytic process are 100% bio-based and provide drop-in replacements for conventional petroleum chemistry. Image Coca-Cola.
