Due to its geographic position, Henderson Island is home to the world’s most plastic-polluted beach. The South Pacific Gyre washes ocean plastic onto the island’s shores, and no one is around to pick it up. Our challenge was to clean up this once-pristine beach, and help tackle the root cause of this pollution.
For the 2019 expedition, through collaboration with Exponent Philanthropy and Charities Aid Foundation of America (CAF America), we connected with a global network of generous donors to philanthropically support the expedition and make this international project a success. Throughout the beach cleanup process, HCF also supported multiple other expedition teams, including scientists gathering data and a climate artist who creates works of art from plastic pollution.
The 2024 expedition was a continuation of our work, both with regard to cleaning up the world's most plastic polluted beach, and in building a global network of partners dedicated to preserving our oceans and pioneering innovative, regenerative solutions to environmental issues.
The 2019 cleanup team that we led successfully cleared 100% of the beach down to bottle cap size materials (~14,000 pounds), overcoming countless headwinds and other challenges. The waste is securely stored on Henderson Island, but couldn’t be removed at the time due to factors outside our control. That said, our beach cleanup efforts provided valuable data to the Expedition’s science team. A number of papers have since been published with our findings about plastic impacts on remote beach ecosystems.
International media coverage of the 2019 project by the embedded New Zealand media team Stuff quickly went global and was covered by digital, print and broadcast outlets in more than 100 publications in over 20 countries. The New York Times profiled the project in late 2020, demonstrating how the story of Henderson Island remains top of mind in the time of COVID as people reconnect with nature, and as it becomes even clearer that we need circular economy solutions for plastics.
The 2019 funding we secured supported the development of a feasible solution for recycling the collected plastics, time-lapse camera equipment to help track long-term accumulation rates of plastic on the beach and other innovative solutions. We established a solid relationship with the Center for Regenerative Design & Collaboration (CRDC), HCF's original partner up-cycle the plastics from Henderson Island.
Henderson Island Plastic Pollution Expedition 2019 was awarded flag #97 by The Explorers Club and won “Expedition of the Year” from the Atlanta Chapter of The Explorers Club.
Henderson Island Plastic Pollution Expedition 2024 was awarded flag #235 by The Explorers Club and was honored as part of the Rolex Expedition Watch Program.
2024 Expedition Highlights:
• Removed over 9 tonnes of plastic waste, including 3.5 tonnes accumulated since the last cleanup in 2019.
• Collected 15,000+ fishing buoys, which were the most prevalent form of waste.
• Filled a total of 55 bags of plastic debris from East Beach.
Scientific Findings:
• Monitoring data revealed that while plastic accumulation persists, the density and weight of debris have decreased compared to 2019, demonstrating the lasting impact of previous cleanup efforts.
• Comparative analysis showed a reduction in average debris density and weight per square meter, highlighting the effectiveness of cleanup interventions.
HCF’s support has not only facilitated the removal of significant plastic waste but has also contributed valuable data to the global understanding of marine debris, empowering strategies for reducing pollution and protecting vulnerable ecosystems worldwide.
