Ocean Cleanup is an engineering-driven effort to remove plastic pollution from oceans and rivers using passive collection systems and data-informed deployment.

At sea, their primary system consists of a long floating barrier with a submerged skirt. It does not chase plastic—instead, it leverages ocean dynamics. Wind, waves, and surface currents push buoyant plastic into the system, while the barrier—moving slightly faster than the surrounding debris due to its design—concentrates it for extraction. Periodically, support vessels remove the accumulated plastic for processing and recycling.

Key technical features:
	•	Passive drift design: Minimizes energy input by using natural ocean forces instead of active propulsion
	•	Hydrodynamic modeling: System geometry is tuned using simulations and field data to optimize retention efficiency
	•	Modular scalability: Systems can be deployed, upgraded, and repositioned based on real-time data from the Great Pacific Garbage Patch
	•	Bycatch mitigation: The system is designed to avoid trapping marine life by using a non-solid barrier and constant monitoring

In parallel, river systems (Interceptors) target plastic before it reaches the ocean. These are solar-powered, autonomous barges that use booms to guide debris onto conveyor belts, extracting waste continuously in high-flow environments.

Why this matters:
An estimated millions of tons of plastic enter oceans annually. Cleanup alone is not a complete solution, but large-scale removal combined with upstream interception and reduced plastic input forms a systems-level approach to mitigation.

Limitations to understand:
	•	Collection efficiency depends on plastic size and buoyancy
	•	Weather and sea state impact operations
	•	Long-term impact requires integration with global waste management improvements

This is a real-world example of applied physics, fluid dynamics, materials engineering, and environmental systems thinking working together at scale.
