About Our Brand Ocean Bottle
Ocean Bottle tackles the urgent crisis of single-use plastic pollution, which sees millions of kilograms of plastic entering our oceans daily, largely from coastal communities lacking proper waste management. The brand provides a tangible way for consumers to contribute to solving this problem, moving beyond vague environmental pledges to deliver quantifiable impact with every product sold.
What truly sets Ocean Bottle apart is its innovative impact model: for each bottle purchased, 11.4 kg of plastic is collected from ocean-bound sources through strategic partnerships with organisations like Plastic Bank. The bottles themselves are thoughtfully designed for daily use, crafted from stainless steel and upcycled ocean-bound plastic, and feature insulation for hot and cold drinks, an anti-leak lid, an easy-carry loop, and are dishwasher safe.
Ocean Bottle integrates sustainability directly into its product transaction, rather than merely using it as a marketing narrative. This model ensures that the environmental impact is clearly defined, quantified, and delivered per unit, establishing a scalable supply chain and partnership approach that grows environmental benefit alongside commercial success.
