Why Ocean Bottle?
close

It's no secret.

Our ocean is having a plastic crisis.

We're addicted to it. Plastic straws, cups, cutlery, crockery, you name it, there's a plastic version of it. Every 30 seconds a truckload of rubbish enters our ocean.

For us at Ocean Bottle, simply providing a reusable bottle isn't enough.

We have to do more.

And so for every single Ocean Bottle sold, we fund the collection of 1000 plastic bottles before they enter the ocean.

If you're not sure what 1000 bottles looks like, check this out…

We work with collectors on the front lines of the ocean plastic crisis in Brazil, Egypt, Haiti, Ghana, India, Indonesia and The Philippines, but we need your help taking part in the solution to turn off the ocean-plastic tap.

Will you help join us?

Hopefully our mission is what got you here but you should also know our product is the best on the market. We've picked up awards and spent hours iterating the design to create the most stylish, functional and sustainable product.
