We work with 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. For more information on the plastic collection we do and why we do it, visit our impact page.

Returns and exchanges are available up to 30 days after delivery. Read our Returns and Refunds Policy for further details.

Our plastic collection efforts are powered by partnerships with some of the world’s most impactful organisations: Plastics for Change, Plastic Bank, and rePurpose Global.

They operate in regions most affected by plastic pollution, preventing waste from entering the oceans while creating vital opportunities for coastal communities. Waste pickers, who collect around 60% of recycled post-consumer plastic globally, are at the heart of this work — helping drive lasting change.

Absolutely! Whether for gifting clients or employees, sharing with business partners, kitting out your team or just dishing out to those you’d like to share the benefits of Ocean Bottle with, branded Ocean Bottles can be produced at volume in the colours of your choosing.
