1st new modular Litter Trap placed in Dordrecht, the Netherlands. This compact installation, to capture marine debris, is placed in the Riedijkshaven in Dordrecht. The Litter Trap will retrieve plastic marine pollution and will prevent further spreading, of litter, into our Dutch waterways and eventually the North Sea. The retrieval device will be emptied on a weekly basis. The Modular Litter Trap is our latest development to stop plastic marine pollution in a durable and (cost) effective manner. The design follows after installing more than twenty Litter Traps in international locations since 2017. The design is compact, modular and easy to implement. The different parts fit into the back of our van. In this way it can easily be transported to its location. After assembly the Litter Trap can be pleased by only two people. The Litter Trap is durable and produced of recycled plastic, making it an important element to achieve a circular economy. The installation in Dordrecht is done in collaboration with Waterschap Hollandse Delta and the Gemeente Dordrecht.

Electric propulsion to stop plastic debris. In Rotterdam we’re concluding the 1st months of our pilot. An electric propeller engine pushes plastic debris out of the fairway towards our newly placed Litter Trap. In this way we will be even more effective with the retrieval of plastic marine pollution in rivers, canals and ports. Solar panels provide a durable energy source. We’ve tested the effect on different kinds of plastic, in different weather conditions and with different engine speeds. The conclusions will be used to optimize the installation. The final installation will have a maximum effect on capturing marine debris, while using a minimum in energy. Please stay tuned! Many thanks to Rotterdam Circulair and Brunel Foundation. 🩵

Additional Litter Trap for Rotterdam! CLEAR RIVERS installed its 4th Litter Trap in the city of Rotterdam. This retrieval device for plastic marine pollution is part of our new pilot to stop plastic pollution also in the fairway. Born from our educational program comes the idea to create a new current to divert plastic marine debris, from the fairway, into our Litter Trap. Last December we had the first successful day of testing in the real life situation and we're currently setting up a three month trail. An electric propeller engine will create a new flow to steer marine pollution. In the first day we've tested any potential negative impact on ships and boats passing by. The new current seems strong enough to divert plastic yet weak enough to effect ship traffic. In the coming months we will further test, optimize and monitor this new way of stopping plastic debris. So please stay tuned! Many thanks to our partners Gemeente Rotterdam, Brunel Foundation, Hoogheemraadschap van Delfland, CrossFit Coolhaven

CLEAR RIVERS starts a new pilot to stop plastic pollution. Born from our educational program comes the idea to create a new current to divert plastic marine pollution, from the fairway, into our Litter Trap. Last week we had the first day of testing in a real life situation. An electric propeller engine creates the new flow to steer floating debris. In the first day we've tested any potential negative impact on ships and boats passing by. The new current seems strong enough to divert plastic yet weak enough to effect ship traffic. In the coming three months we will further test, optimize and monitor this new way of stopping plastic debris. So please stay tuned! Many thanks to our partners Gemeente Rotterdam, Brunel Foundation, Torqeedo, CrossFit Coolhaven.

We're excited to share CLEAR RIVERS educational video in Vietnamese! This project is the result of a collaboration with the Graphic Lyceum Rotterdam, where a talented group of students poured their creativity into translating our mission into engaging visuals. This video will be used in our educational programs, helping us explain the significant impact of plastic pollution on water bodies, and how even small pieces of trash can cause big problems for marine life. The animation introduces the innovative Litter Trap, an invention by CLEAR RIVERS that acts like a superhero, capturing trash before it reaches the ocean. Our mission extends beyond just cleanup efforts; we aim to change how people think about and handle trash in their daily lives. By keeping the environment clean and working together, we can make a huge difference. Join us in protecting our rivers and oceans.

The Litter Trap pilot in the Gent-Terneuzen canal comes to an end after one year of effective retrieval and monitoring. Many thanks to our project partners Heijmans and Coca-cola Europacific partners. Within this pilot we've seen how our Litter Trap can be effective in large canals with ongoing ship traffic. The Litter Trap was successful in retrieving cross-border (Belgium-The Netherlands) macro marine pollution. But, also a shockingly large quantity of micro plastics was recovered from the water column. Especially the plastic nurdles / pallets were found in large number in the canal that connects the city Gent with the North Sea. Currently we are exploring a new location for this Litter Trap.

Litter Trap Opening in Budapest!

  • Sep 21, 2021

Today the first Litter Trap in Budapest has been launched. The project is the result of a wide and successful collaboration between different national and international partners that have worked together in order to present the project during today's inauguration in front of the Budapest University of Technology and Economics.


The plastics collected by the floating Litter Trap will be monitoring and analysed in its recycling potential for the production of new durable products. The Litter Trap will collect plastic litter floating along the West bank of the Danube river. Collected plastics will be sorted and recycled. Education and awareness creation will be a fundamental aspect of the one-year-long pilot.


Thank you to all our partners in this project: Audi Umweltstiftung, Kszgysz, Pet Kupa, ING, Audi Hungary, Europahajo, Budapest University of Technology and Economics.

We are excited to start retrieving litter here in Feyenoord, Rotterdam!


One month of CLEAR RIVERS' Litter Trap in Zwolle!

  • Sep 2, 2021

CLEAR RIVERS started a new pilot project in Overijssel with the aim of preventing the plastic from entering the Ijsselmeer first and, later, from reaching the North Sea.


The Litter Trap has been successfully retrieving waste from the river for a month now.

CLEAR RIVERS' team is monitoring and emptying the Litter Trap weekly, keeping track of the different type and amounts of waste collected. The plastic litter will be analyzed for quantity, composition and type of plastic.


But the pilot doesn't end with the retrieval of the plastic:

A fundamental part of the project is the recycling. Researches will be done in order to recycle as much as possible of the collected material.

The pilot is a CLEAR RIVERS’ initiative, supported by the Provincie Overijssel, the Gemeente Zwolle, SC Johnson, Rijkswaterstaat and ENGIE. Various partners are participating in the pilot, such as Saxion University of Applied Sciences, Windesheim, OOZ, Natuur & Milieu.

We are looking forward to delivering the first results and insights of the pilot project.
