The Interceptor™
80% of river plastic
stems from
1000 rivers
Rivers are the main source of ocean plastic pollution. They are the arteries that carry waste from land to the ocean. Our research found that 1000 rivers are responsible for roughly 80% of the pollution.
We aim to tackle plastic in 1000 rivers in 5 years
To rid the oceans of plastic, we need to not only clean up what is already out there, but also stop new plastic from entering the ocean: we need to close the tap. Working together with government leaders, individuals, and private corporations, our goal is to tackle these 1000 most polluting rivers all over the world, in five years from rollout.
The Interceptor
The Interceptor is The Ocean Cleanup’s answer for river plastic waste. It is the first scalable solution to prevent plastic from entering the world’s oceans from rivers.
It is 100% solar-powered, extracts plastic autonomously, and is capable of operating in the majority of the world’s most polluting rivers.
How it works
-
Scalable
The Interceptor has been designed for mass production and can be applied virtually anywhere in the world.
-
Energy neutral
The debris enters the Interceptor with the natural current of the river. All electronics on the Interceptor, including the conveyor belt, shuttle, lights, sensors, data transmission, are solar-powered.
-
Connected
The Interceptors are internet-connected, allowing us to gather continuous performance and collection data. It also enables the Interceptor™ to automatically notify local operators once the dumpsters are full.
Placement in rivers
Alongside our research into the most polluting rivers, we have also conducted research on where to best place Interceptors in the rivers.
The optimal setup is determined on a case-by-case basis, based on flow-velocity, the width of the river, presence of a plastic “hotline” , traffic, proximity to a delta, etcetera.
Working with the government and local operators we will help to determine the best setup that produces the most effective extraction output and the least interference with vessel traffic in the river.
-
50,000 kg/day
The Interceptor can extract 50,000 kilograms of plastic per day. In optimal conditions, up to double this amount can be achieved.
-
24/7 operation
The Interceptor can work autonomously until it’s full and can continue extracting debris even when the dumpsters are being emptied.
-
50 m3 capacity
Its large storage capacity allows for efficient emptying cycles, filling entire garbage trucks at once.
Interceptors™
deployed
We currently have two Interceptors deployed and are working with governments all over the world to deploy in more rivers.
Cengkareng Drain
Jakarta, Indonesia
The very first Interceptor, our prototype, is currently deployed in the Cengkareng Drain in Jakarta. The Ocean Cleanup met with members of the government of Indonesia for the first time in 2016. Jakarta was chosen as the starting place since DKI Jakarta already conducted cleanup operations in rivers here.
We are looking forward to expanding the cooperation within Jakarta and within the rest of Indonesia in the future.
Klang River
Klang, Selangor, Malaysia
The Klang River runs through Kuala Lumpur. According to our research, the Klang River is one of the 50 most polluting rivers worldwide.
In 2016, Landasan Lumayan Sdn. Bhd. (LLSB) implemented the Selangor Maritime Gateway initiative, aimed at rejuvenating the Klang River. Therefore, together with the local government, the Interceptor was a welcome addition to their own cleanup efforts, using barriers in the river to stop the plastic flow to the ocean. The Interceptor helps to improve the cleanup efficiency, making for quicker and more scalable cleanup. The intention is to deploy more cleanup systems throughout Malaysia.
Help us tackle 1000 rivers in 5 years
We see ourselves as the architects for river projects to stop the inflow of plastic into the oceans. The Ocean Cleanup brings in the knowledge (where and how to intercept riverine plastic), provides solutions (e.g. the Interceptor), and uses its network to raise awareness and help attract funding and financing.
Given the scale and the urgency of the issue, we need partners to reach the goal of tackling plastic in the 1000 most polluting rivers in 5 years from rollout.
-
Execute
Operators
Local partners operate the Interceptors™ to extract the waste from the river and bring this to land. They work together with responsible waste handlers to sort debris and recycle plastic where possible. -
Initiate
Governments and river owners
Operators need support from (local) governments for permits to operate in their rivers. Collection fees from governments and cities help safeguard continuity in waste extraction by the operators. -
Accelerate
Funders and sponsors
Funders, sponsors, and investors make river cleanups possible and accelerate the deployment of Interceptors™. With your help, we build consortia to clean rivers where most necessary.
The 1000 top polluting rivers
In order to reach our mission of tackling 1000 rivers, we need help from individuals all over the world in spreading the message of the top polluting rivers and the solution we aim to bring.
The price tag of plastic pollution
According to a study conducted in collaboration with Deloitte, yearly economic costs due to marine plastic are estimated to be between $6-19bn USD. The costs stem from its impact on tourism, fisheries and aquaculture, and (governmental) cleanups. These costs do not include the impact on human health and the marine ecosystem (due to insufficient research available). This means that intercepting plastic in rivers is much more cost-effective than dealing with the consequences downstream.
The Interceptor unveil
On October 26th, 2019, Boyan Slat presented the interceptor to the world, in Rotterdam, the Netherlands. In this presentation, he explained the research behind the finding the most polluting rivers, how the Interceptor works, as well as the next steps.
