The Challenge

If a reusable water bottle is filled with a sugary drink or a shake, the bottle retains the smell and taste of that drink long after it is gone. This leads consumers to dispose of their water bottles more quickly, creating unnecessary waste.

Innovation Details

Purist technology uses silicon dioxide to create an ultra-thin glass finish on the inside of water bottles that is similar to the surface of a lotus leaf. The glass finish is just 60 nanometers thick – thinner than a fraction of one strand of human hair. This technology provides all the benefits of typical glass, but due its ultra-thin nature, it will not crack or break. This finish creates a barrier between your beverage and the raw stainless container, making the surface completely smooth and pure for better taste and easier clean.

Biomimicry Story

Lotus plants stay dirt-free, an obvious advantage for an aquatic plant living in typically muddy habitats. The surface of the lotus leaf contains microscopic bumps that prevent water molecules from adhering to the surface. Instead, the water rolls right off, and picks up any dirt or oil on the surface of the lotus leaf along the way.
