System 002 / "Jenny"
At the end of July 2021, we returned to the Great Pacific Garbage Patch (GPGP) to trial System 002, the latest iteration of our ocean cleanup system. It is our first large-scale cleanup system. The 12-week test campaign has now been concluded successfully – we have now reached proof of technology. System 002 will continue harvesting plastic in the Great Pacific Garbage Patch, and in tandem, we have started working on System 03, a larger, upgraded ocean system, which is expected to be the blueprint design for scaling to a fleet of systems.
Ocean System Iteration
To succeed in our mission, we need a cleanup technology that not only captures plastic but whose design and operation are suited for growth into a global fleet. System 001/B (2019), achieved a relative speed difference that resulted in effective collection and retention of plastic. However, in order to achieve a goal of 90% reduction of floating ocean plastic by 2040, its parachute sea anchor design would require us to deploy hundreds of systems. To us, this is unfeasible, so we continued to advance our research and design. With a persistent problem that grows worse by the day, there is an urgency to reduce pollution as quickly as possible.
System 002 Test Plan
The System 002 test campaign in the Great Pacific Garbage Patch took place over 12 weeks (July to October 2021). The tests were successful and we can now confirm proof of technology. Watch us celebrate this moment on October 20th, 2021.

In about 1.5 months, we will be launching our first large-scale cleanup system, System 002, in hopes of multifold impact. We just tested the retention zone (pictured), which is designed to hold plastic until it's offloaded. For reference: it is as big as a school bus. -

View on FacebookMeet System 002, aka Jenny. In about two weeks, we are returning to the Great Pacific Garbage Patch (GPGP) with the next iteration of our ocean cleanup design. Based on our learnings from System 001/B, we have now incorporated active propulsion into the design.
What are the main benefits of this design feature? 1) We can now steer to high-density zones to accelerate the cleanup process, 2) Boosted span, speed, and efficiency = reduced cost/kg of plastic removed, 3) Quicker time to scale up, because of simpler, readily available technology, And if it works, we expect to be able to clean an area equal to 1 football field of ocean every 15 seconds. -

View on YoutubeThe crew offshore in the Great Pacific Garbage Patch achieved our largest ocean plastic catch to date in a single extraction with System 002 on September 22nd, 2021. This load amounts to 3.8 tons and concludes the last short test of the campaign.
The next weeks will see the crew putting the system to longer tests, potentially harvesting significantly more. While we look forward to bigger catches, the reactions of the crew members as the deck gets filled with trash are already an indication of how close we are to proving the capacity and efficiency of our latest system. -
View on FacebookOur ocean system is designed to catch floating plastic, not marine life. Here’s how:
- The system is towed at a very slow and constant speed of max 1.5 knots (think: half of a normal walking speed), so marine life can easily swim in, out, and around the system - We designed the system to have various mitigation measures: a quick release system, escape routes, cameras in the retention zone, lights, etc. - Protected Species Observers, marine biologists, and other crew are on board to monitor, report, and advise on marine life interactions. -

View on YoutubeYear-end wrap-up videos are a social media essential these days, so here is a recap of what happened at The Ocean Cleanup in 2021.
It’s been another incredible ride for our team, and we look back at these 365 days during which we made substantial progress on our mission to rid the world’s oceans of plastic. From groundbreaking research to global partnerships, from reaching proof of technology with our latest ocean system to new Interceptor deployments in rivers, we navigated tumultuous seas and were greeted by stunning rainbows. If we had to give one number to sum it up, it would be 816,671 kg (and counting!) - our total combined catch in rivers and oceans this year. Of course, we look forward to crushing this number next year. And above all, thanks to all of you, supporters, partners, and followers for the growing enthusiasm year after year. -
View on TwitterOur crew has reached the Great Pacific Garbage Patch (GPGP) and is getting ready to deploy Jenny at the marked location. We’ll then head for the red area – the hot spot where plastic density is expected to be high.
But ocean garbage patches aren’t solid ‘islands’ of trash. Instead, the plastic is dispersed throughout these accumulation zones, yet with a much higher concentration than in surrounding waters. The average concentration in the GPGP is around 60 kilograms per square kilometer, peaking at several hundred kilograms per square kilometer. -
View on FacebookAnother collection of strange objects the crew extracted from the Great Pacific Garbage Patch.
Fun fact: the trash we extract appears relatively clean because the Great Pacific Garbage Patch is far from key nutrient sources (coastal waters, deep water rising). As a result, you will see far less sea life growing on the plastic since there are simply not enough nutrients to grow. -

View on TwitterThe Great Pacific Garbage Patch (GPGP) is the largest of the five offshore plastic accumulation zones in the world's oceans, with ≈100 million kilos of floating plastic. After scale-up in the GPGP, we'll look into deploying a fleet of systems in the other ocean gyres.
What's next? Models indicate a significant accumulation of floating plastics in the Indian Ocean gyre (likely largest after the GPGP) due to large river sources. Still, there is limited observational data from this region to confirm the extent and location of the pollution. This year, our research team started to map the extent of floating plastic pollution in the Indian Ocean subtropical gyre during a 21-day expedition from Reunion Island into the western part of the subtropical gyre and back (≈5500km), sampling different sizes of debris. The expedition consisted of remote sensing of mega (>50 cm) and macro (5cm - 50cm) plastic debris, visual observations, and manta trawl to investigate the concentration of microplastics. Gathered data will be supported with another 2 expeditions over the coming 3 years. -
View on YoutubeWe transformed the plastic catch from System 001/B into our first product – sunglasses and have recently reached the goal to fund the cleaning of 500,000 football fields worth of ocean. Here are some reflections about the entire journey from trash to treasure.
The Ocean Cleanup sunglasses were a proof of concept that ocean plastic can be transformed into beautiful, sustainable products. What's next? Our plan is to work with partners to recycle the plastic and transform it into durable plastic products. By recycling the collected ocean plastic into beautiful products that are made with certified plastic from the Great Pacific Garbage Patch, we aim to make the cleanup operational costs, to a large extent, financially self-sustainable.
