A packaging revolution: Danone and Nestlé Waters, the world’s two largest bottled water companies, have joined forces with Origin Materials, a startup based in Sacramento, California, to form the NaturALL Bottle Alliance. Together, the three partners aim to develop and launch at commercial scale a PET plastic bottle made from bio-based material, i.e. 100% sustainable and renewable resources. PET (Polyethylene terephthalate) is the most common plastic in polyester family and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.
