About Ocean Bottle:

At Ocean Bottle, our vision is to restore the health of the ocean to a better state than we inherited it. We do this by bringing people together to fund plastic collection. We create award-winning reusable bottles and cups, with every product sold funding the collection of 1000 plastic bottles in weight - before they reach the ocean. To date, we’ve collected the equivalent of 1.7 billion plastic bottles from ocean-bound regions.

We believe that we don’t need a handful of people doing sustainability perfectly, we need millions doing it imperfectly. Our products and solutions enable consumers and businesses to drive this change and support refill behaviour whilst funding plastic collection. 

As a brand, we are change makers - we bring people together, we pioneer solutions and we connect others to the power of the ocean. Are you ready to join us on this mission?
