The Ocean Cleanup: From Viral TED Talk to Global Impact
In 2013, Boyan Slat, then an 18-year-old Dutch aerospace engineering student, presented a solution to ocean plastics in a TEDx Talk. His project, The Ocean Cleanup, has since retrieved over 50 million kilograms (110 million pounds) of plastic from the world’s oceans.
Overcoming Early Challenges
The Ocean Cleanup faced initial technical difficulties and setbacks. However, the organization and its engineers persevered, developing operational and afloat autonomous robots capable of making a significant impact.
Targeting the Source: Rivers as Key Contributors
Research has revealed that a relatively modest number of rivers are responsible for a large percentage of plastic entering the oceans. A 2021 study in Science Advances identified 1,000 rivers as the source of approximately 80% of oceanic plastic.
The 30 Cities Program: A Focused Approach
Leveraging this data, The Ocean Cleanup launched the 30 Cities Program, focusing on the 30 urban areas with the most problematic infrastructure regarding plastic waste. This initiative targets waterways before plastic reaches the open ocean.
The program involves “coastal sweeps” along river mouths, mangroves, beaches, and barrier reefs, in collaboration with local governments, from locations like Los Angeles to Mumbai.
A Detailed Process: Assessment, Partnerships, and Deployment
The Ocean Cleanup’s process begins with “city assessments,” including stakeholder meetings, permitting, and preliminary research using the Smart River Survey. This information informs further data collection and analysis, followed by securing partnerships and funding.
Different geographies require different plastic intercepting devices. Once deployed, interceptors are monitored using drones, GPS trackers, remote-sensing cameras, and time-lapse surveys. The composition of the collected plastic is also recorded.
Scalability and Future Ambitions
The Ocean Cleanup has demonstrated a scalable, tailorable, and repeatable system. The organization aims to remove virtually all plastics adrift in the oceans by 2040, with an estimated need for an additional $1 billion in funding.
The Evolution of the Technology
The initial design proposed in 2012 consisted of long, floating barriers fixed to the seabed, attached to a central platform shaped like a manta ray. This design has evolved over time as the project has matured.
The Ocean Cleanup: A Non-Profit Foundation
Founded in 2013 by Boyan Slat, The Ocean Cleanup is a non-profit foundation based in the Netherlands. The organization relies on donations from individuals, corporations, governments, and institutions and employs over 150 professionals.
