World's Largest Ocean Plastic Garbage Cleaning System - "The Ocean Cleanup"
The Largest Cleanup In History - OVER 5 TRILLION PIECES OF PLASTIC CURRENTLY LITTER THE OCEAN. Trash accumulates in 5 ocean garbage patches, the largest one being the Great Pacific Garbage Patch, located between Hawaii and California. If left to circulate, the plastic will impact our ecosystems, health and economies. Solving it requires a combination of closing the source, and cleaning up what has already accumulated in the ocean.
The Ocean Cleanup develops advanced technologies to rid the world’s oceans of plastic. A full-scale deployment of our systems is estimated to clean up 50 \% of the Great Pacific Garbage Patch in 5 years.
Ocean garbage patches are vast and dispersed
Ocean currents concentrate plastic in five areas in the world: the subtropical gyres, also known as the world’s "ocean garbage patches". Once in these patches, the plastic will not go away by itself. The challenge of cleaning up the gyres is the plastic pollution spreads across millions of square kilometers and travels in all directions. Covering this area using vessels and nets would take tens of thousands of years and cost billions of dollars to complete. How can we use these ocean currents to our advantage?
Algorithms help specify the optimal deployment locations, after which the systems roam the gyres autonomously. Real-time telemetry will allow us to monitor the condition, performance and trajectory of each system.
Our systems fully rely on the natural ocean currents and do not require an external energy source to catch and concentrate the plastic. All electronics used, such as lights and AIS, will be powered by solar energy.
By gradually adding systems to the gyre, we mitigate the need for full financing upfront. This gradual scale-up also allows us to learn from the field and continuously improve the technology along the way.
THE IMPACT OF CLEANUP
Our models indicate that a full-scale system roll-out could clean up 50\% of the Great Pacific Garbage Patch in 5 years.
Research shows the majority of plastic by mass is currently in the larger debris. By removing the plastic while most of it is still large, we prevent it from breaking down into dangerous microplastics.
Combining the cleanup with source reduction on land paves the road towards a plastic free ocean by 2050.
