water and oil simply do not mix. that’s why our bottle is made from surplus plants and not petroleum-based plastic. the materials used are grown from our own soil, and just as easily returned to it. through our partnership with NatureWorks, we use the Ingeo polymer to create our bottles. this ingenious polymer offers unique alternatives to traditional PET bottles, including 100% recycling, industrial composting, and even incineration. re:newal spring water is a corn based bottle. this PLA bottle is a biodegradable water bottle, with the great taste of a natural spring water.
