Ocean Cleanup may be best known for deploying massive garbage collectors in the Great Pacific Garbage Patch, but it’s also trying to keep plastic litter out of the ocean. The newest interceptor ship will prevent about 1,000 tons of plastic from entering the Java Sea from Indonesia’s Cisadane River each year.

The Interceptor was launched in October 2019, but by then the Type 001 was already on a mission to clean up the Cengkareng drain in Jakarta, Indonesia, followed by similar operations in Malaysia and Vietnam.

Essentially a solar-powered barge fitted with a conveyor system and multiple bins, the vessel dips into the flowing river through one or two floating barriers, directing plastic debris into its belly for subsequent onshore collection and processing. It is also capable of operating autonomously on water.

The fleet, which now operates from five locations around the world, including Los Angeles, has so far prevented more than 2 million kilograms of trash from entering the world’s oceans — although The Ocean Cleanup says “approximately 80 percent of riverine plastic pollution originates in 1,000 rivers,” so there are still work to be done.

The Cisadane River is considered a high priority by The Ocean Cleanup and Indonesian authorities, and Interceptor 020 will now be deployed by the end of 2023 to help Indonesia reduce marine plastic litter by 70% by 2025.

“We are pleased to support The Ocean Cleanup and the Dutch government’s participation in the deployment of interceptors on the Cisadane River,” said Jarot Widyoko, Director of the Water Resources Division of the Indonesian Ministry of Public Works and Housing. “This is a step towards working together with the Tangerang Regency Government to reduce the flow of plastic waste from rivers into the ocean.”

This latest deployment is part of a global implementation partnership signed with Coca-Cola in 2021, with funding also coming from True Venture and ThatGamingCompany. Project partners include BBWS Cilliwung-Cisadane, Tangerang Regency – DLHK and Tanjung Burung Waste Bank. Other solutions in the Interceptor portfolio include waste filtration pens, self-contained floating barriers and small power supply vessels.
