The Ocean Cleanup’s System 03 Captures Record Amounts of Plastic From the Pacific

Summary

The Ocean Cleanup has launched its largest system yet, System 03, spanning 2.5 km to capture plastic pollution in the Great Pacific Garbage Patch. Combining advanced hardware and software, the system funnels debris into collection bags while prioritizing marine life safety. Since 2021, cleanup efforts have grown from 7 to 45 tons per trip, with a goal of 100 kilos per hour. System 03 also collects valuable ocean data, and recovered plastic is recycled, including partnerships with companies like Kia. Additionally, river Interceptors prevent plastic from reaching oceans, addressing pollution at its source and protecting waterways worldwide.

Takeaways

• 🌊 The Ocean Cleanup has deployed its largest system yet, System 03, which spans 2.5 km and targets the Great Pacific Garbage Patch between California and Hawaii.
• 🛠️ System 03 consists of a physical U-shaped barrier to collect plastic and advanced software models to guide its path through high-density plastic zones.
• 🚢 The U-shaped barrier funnels ocean plastic into a collection bag called the retention zone, which is periodically emptied and returned to continue cleanup operations.
• ⚡ System 03 is three times larger than System 2, allowing it to sweep an area the size of a football field every five seconds.
• 📈 Cleanup progress has increased from 7 tons of plastic in the first expedition to 45 tons per trip in 2023, with the goal of reaching 100 kg per hour for large-scale cleanup.
• 🐟 System 03 includes enhancements for marine life safety, such as a safety hatch and inflatable escape route, and moves slowly to allow animals to avoid capture.
• 🛰️ Satellite data and computer models are used to predict plastic hotspots, optimizing cleanup efficiency by targeting the areas with the highest plastic density.
• ♻️ Collected plastic is sorted on board, brought to shore, processed, recycled, and repurposed; partnerships include companies like Kia using recycled ocean plastic in car parts.
• 🏞️ Beyond oceans, the organization deploys river interceptors to stop plastic from reaching the ocean, aiming for 1,000 barriers on the world's most polluting rivers.
• 🌐 Public engagement is encouraged through donations, awareness, and advocacy to support plastic pollution solutions and protect wildlife and coastlines.

Q & A

What is System 03 and what is its purpose?

System 03 is the Ocean Cleanup's largest and most ambitious ocean cleanup system, spanning 2.5 km, designed to capture floating plastic pollution in the Great Pacific Garbage Patch.

How does System 03 physically collect plastic from the ocean?

It uses a 2.12 km U-shaped barrier towed by two ships, which funnels plastic into a retention zone (a large collection bag). The collected plastic is then periodically removed for sorting and recycling.

What role does software play in System 03 operations?

Advanced computer models, fed by satellite data and prior measurements, guide the ships to high-density plastic areas, optimizing the cleanup path much like a weather forecast directs planning.

What improvements does System 03 have over previous systems?

System 03 is three times the span of System 2, allowing faster coverage. It also includes deeper and higher barriers, 16 cameras, a marine animal safety hatch, and slow movement speed to protect marine life.

How much plastic has been collected historically, and what are future goals?

System 2 collected 7 tons in 2021 and 45 tons in late 2023. System 03 aims to achieve 100 kg/hour, with potential future goals of 200–300 kg/hour to clean the Great Pacific Garbage Patch within 10 years.

What safety measures are in place for marine life during cleanup operations?

System 03 moves slowly (~half walking speed), has a remotely activated marine animal safety hatch with inflatable bellows to allow escape, and uses cameras to monitor wildlife near the system.

Who comprises the Ocean Cleanup crew and how are operations conducted?

The crew includes over 40 personnel, including Ocean Cleanup employees and contractors, operating from two large vessels with smaller support ships. Missions take about seven weeks in spring and summer.

What happens to the plastic collected by System 03?

Collected plastic is sorted into categories such as ropes, nets, and solid pieces. It is then processed, pelletized, and recycled. Partners like Kia Motors use the recycled material for products, including car parts.

What are river interceptors and why are they important?

River interceptors are systems designed to stop plastic from entering oceans by capturing it in rivers. Intercepting plastic at its source is faster and more cost-effective, as 1% of rivers contribute 80% of ocean-bound plastic.

Can you give examples of river interceptor deployments?

Interceptor 19 was installed in the Chao Phraya River in Bangkok, Thailand, and Interceptor 007 operates in Los Angeles, California. These systems help prevent pollution from reaching the ocean while providing insights for future deployments.

How does the Ocean Cleanup use data to maximize effectiveness?

Satellite data, past measurements, and advanced computer models identify high-density plastic hotspots. Ships follow optimized paths, targeting these areas to maximize collection efficiency.

How can the public support the Ocean Cleanup efforts?

People can support by donating, raising awareness, or contacting local officials to advocate for solutions to reduce plastic pollution, helping protect beaches, coastlines, and wildlife.
