Why Ocean Bottle?

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…

1000 Bottles Looks Like

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.

We work with 3 Plastic Collection Partners on a global scale, in areas where plastic pollution is worst. We collect all types of plastic and always ensure it is recovered and reprocessed in as efficient and socially beneficial a way as possible.

IMPACT THAT COUNTS

We go beyond sustainability, supporting livelihoods for people in coastal communities while keeping plastic out of our ocean.

For every Ocean Bottle sold we commit to the collection of the equivalent of 1000 plastic bottles. That’s 11.4kg of plastic put to better use. Collectors trade plastic for money and get access to social resources such as healthcare, tuition, tech, and microfinance.
