Every year, the world produces around 300 million metric tons of plastic. Unfortunately, a lot of this plastic ends up in our rivers and oceans, and it can even make its way into the food we eat. This is a big problem, but a group called The Ocean Cleanup believes they have some new technology that can help solve it.
When plastic gets into the ocean, sunlight and other environmental factors break it down into smaller pieces. Marine animals often mistake these tiny plastic bits for food, which can make them sick and fill their bodies with harmful chemicals. Since humans eat some of these marine animals, the plastic can end up in us too.
The Ocean Cleanup is focusing on a massive area in the ocean called the Great Pacific Garbage Patch. This area is about three times the size of France and contains over 1.8 trillion pieces of plastic. It’s located in the North Pacific Ocean and is a major target for cleanup efforts.
The Ocean Cleanup has created a system to tackle this problem. It uses a 160-meter-long floater to stay buoyant, with a 3-meter deep netted skirt hanging below. This skirt catches plastic while letting marine animals swim underneath. The system is shaped like a U to funnel plastic into the net, and it has a parachute to control its speed. GPS devices help track its location.
After a year of testing, The Ocean Cleanup announced that their system is working. However, some experts worry that it might harm marine life, especially creatures living on the ocean surface. Others argue that it might be better to focus on simpler solutions like beach cleanups or devices like Mr. Trash Wheel, which stops plastic from reaching the ocean.
In response to these concerns, The Ocean Cleanup developed a new project called The Interceptor. This device captures plastic closer to shore, especially at river mouths. They found that just 1% of the world’s rivers are responsible for 80% of ocean pollution, with small urban rivers being the biggest contributors. Their goal is to tackle these 1,000 rivers by 2025.
The Interceptor is anchored in the riverbed where plastic waste is concentrated. A floating barrier guides the plastic into the Interceptor, where the river current pushes it onto a conveyor belt. The belt separates the plastic from the water and moves it into one of six dumpsters. Sensors alert local operators when the dumpsters are full, so they can be emptied and the trash processed.
The Interceptor can remove over 100,000 kilograms of trash per day and is already in use in Jakarta, Indonesia, and Malaysia’s Klang River. Plans are underway to deploy more systems in Vietnam’s Mekong Delta and Santo Domingo in the Dominican Republic. Discussions are also ongoing with Thailand and LA County for future collaborations.
To see how effective The Ocean Cleanup is, we need to monitor the performance of the Interceptors. To reach their goal of deploying systems in 1,000 rivers by 2025, a new Interceptor needs to be deployed every two days. Will they succeed? With determination and a bit of luck, we might soon see a fleet of these devices cleaning our rivers and oceans for future generations.

It’s well-known that we have a significant waste problem. Annually, we produce approximately 300 million metric tons of plastic worldwide. This plastic can end up in rivers, oceans, and eventually in our food chain. A group called The Ocean Cleanup claims that their new suite of technologies can help address this growing issue.
When plastic enters the ocean, exposure to sunlight and environmental factors breaks it down into smaller fragments. Marine animals often mistake plastic for food, which can lead to malnutrition and a potential accumulation of harmful chemicals in their bodies. Since humans are part of the food chain, plastics can also find their way into us.
With this in mind, The Ocean Cleanup team focused on tackling the world’s largest accumulation zone: the Great Pacific Garbage Patch. This area in the ocean is bounded by the North Pacific Subtropical Gyre and is about three times the size of France, containing over 1.8 trillion pieces of plastic.
Here’s how The Ocean Cleanup’s system works: A 160-meter floater provides buoyancy, while an attached extended corkline floats above a 3-meter deep netted skirt. The skirt is designed to catch plastic while allowing marine creatures to swim beneath it. The system is shaped in a U to funnel plastic into the net, with a parachute at the back to control speed. The entire system is equipped with GPS for location monitoring.
This October, after a year of testing and some setbacks, The Ocean Cleanup team announced that its plastic-collecting system is operational. Despite this success, the team has faced criticism from some experts who believe the device could harm marine life, particularly organisms that live on the ocean surface. Additionally, some critics argue that building an expensive structure far from shore overlooks more practical and cost-effective measures, such as volunteer beach cleanups and technologies like Baltimore’s Mr. Trash Wheel, which can prevent plastic from reaching the ocean.
It seems The Ocean Cleanup team took these criticisms to heart. While refining their offshore cleanup system, they also developed a new project called The Interceptor, designed to capture plastic closer to shore, specifically at the mouths of rivers.
To prioritize their efforts, The Ocean Cleanup team measured how much plastic flows from rivers into the ocean. They discovered that just 1% of the world’s rivers—1,000 out of 100,000—are responsible for about 80% of ocean pollution, with small urban rivers contributing the most. Their goal is to address all 1,000 of these rivers by 2025.
The Interceptor is anchored in the riverbed at strategic locations where plastic is concentrated. A floating barrier guides plastic waste into the Interceptor, where the river current helps push it onto a conveyor belt. As debris moves across the belt, it is separated from the water and delivered to a shuttle that distributes it into one of six dumpsters. Sensors notify local operators when the dumpsters are full, prompting them to remove the trash for processing.
At peak performance, this solar-powered device can extract over 100,000 kilograms of trash per day. While the comparative cost of this system versus other cleanup efforts is not yet known, The Ocean Cleanup states that the Interceptors are ultimately more cost-effective than doing nothing.
The Interceptors are already operational in Jakarta, Indonesia, and Malaysia’s Klang River. The group is also preparing to deploy additional systems in Vietnam’s Mekong Delta and Santo Domingo in the Dominican Republic, a location known for significant plastic pollution after heavy rains. Discussions are ongoing with Thailand and LA County for future collaborations.
To evaluate how effective The Ocean Cleanup is at preventing plastic from reaching our oceans, we will need to assess the initial performance of the Interceptors. To meet their goal of deploying systems in 1,000 rivers by 2025, a new Interceptor will need to be deployed every two days. The question remains: can they achieve this? With some luck, we may soon see a fleet of these devices working to clean our rivers and oceans for future generations.
