The Ocean Cleanup Deploys Its Plastic-Cleaning Device

The Ocean Cleanup, the Dutch non-profit organization developing technologies to rid the oceans of plastic, has launched the world’s first ocean cleanup system from the San Francisco Bay.

The cleanup system (System 001) is set for a two-week trial before continuing its journey toward the Great Pacific Garbage Patch, 1,200 nautical miles offshore, to start the cleanup.

System 001 was towed from the San Francisco Bay by the vessel Maersk Launcher, which has been made available to the project by A.P. Moller-Maersk and DeepGreen, its current charter holder.

Hundreds of scale-model tests, a series of prototypes, research expeditions and multiple iterations have led to The Ocean Cleanup having sufficient confidence in its technology to launch its first full-scale cleanup system.

The System 001 consists of a 600-meter-long (2000 ft) U-shaped floating barrier with a three-meter (10 ft) skirt attached below. The system is designed to be propelled by wind and waves, allowing it to passively catch and concentrate plastic debris in front of it. Due to its shape, the debris will be funnelled to the center of the system. Moving slightly faster than the plastic, the system will act like a giant Pac-Man, skimming the surface of the ocean.

The system will be deployed in the Great Pacific Garbage Patch, the world’s largest accumulation zone of ocean plastics. Situated halfway between Hawaii and California, the patch contains 1.8 trillion pieces of plastic, and covers an area twice the size of Texas.

The Ocean Cleanup anticipates that the first plastic will be collected and returned to land within 6 months after deployment. This will mark the first time that free floating plastic will have been successfully collected at sea. After returning the plastic to land, The Ocean Cleanup plans to recycle the material into products and use the proceeds to help fund the cleanup operations.

While the main objective of System 001 is to prove the technology and start the cleanup, a secondary goal is to collect performance data to improve the design for future deployments. Hence, the system is equipped with solar-powered and satellite-connected sensors, cameras and navigation lights to communicate the position of System 001 to passing marine traffic, and enable monitoring of the system and the environment. After delivery of the system to the Great Pacific Garbage Patch, the Maersk Launcher will remain active as an observation platform for several weeks.

Once successful, and if the funding is available, The Ocean Cleanup aims to scale up to a fleet of approximately 60 systems focused on the Great Pacific Garbage Patch over the next two years. The Ocean Cleanup projects that the full fleet can remove half of the plastic in the Great Pacific Garbage Patch within five years’ time. This is in line with The Ocean Cleanup’s ultimate goal: reducing the amount of plastic in the world’s oceans by at least 90% by 2040.
