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.

The Usual sponsors our Litter Trap in Brussels, Belgium. This new partnership allows a continued operation in the Brussels-Charleroi canal. The Litter Trap is originally placed in 2018 and is frequently emptied by the Port of Brussels. Last year 50m3 of floating litter was collected and removed from the water. Does your company also want to support our Litter Trap placements, then please contact us via info@clearrivers.eu

In the Autumn we've intensified our Clean up actions in the Netherlands again. Several cleanups were organised in Rotterdam and Amsterdam. Together with local companies, volunteers and students we've cleaned the canals, quays and streets to prevent further disperse of plastic waste. If you and your school or company also want to hold a cleanup with us, then please contact us via info@clearrivers.eu

We are excited to share the latest progress on our Ambon plastic-free project. Thanks to the generous support of the AFAS Foundation, we have successfully installed three Litter Traps in Ambon, marking a significant step towards our goal. These Litter Traps will play a vital role in preventing waste from reaching Ambon Bay while simultaneously raising awareness about the urgent issue of plastic pollution.

In addition to the Litter Traps, CLEAR RIVERS actively engages with local organizations to organize regular clean-up activities, ensuring the continuous upkeep of a clean and sustainable environment. However, our commitment extends beyond cleanup efforts. We firmly believe that addressing plastic pollution requires a comprehensive approach that tackles prevention, encompassing education, awareness, and recycling.

To involve future generations in solving this crisis, we have established an educational program in collaboration with local schools. Through this initiative, the CLEAR RIVERS team engages children in discussions about the consequences of plastic pollution and encourages their active participation in activities aimed at finding innovative solutions.

Moreover, we recognize that recycling and reusing plastics are crucial steps in preventing the collected waste from re-entering our ecosystems. In partnership with local and international allies, CLEAR RIVERS is actively working towards a circular economy that gives plastic a second life. This collaborative effort ensures that plastic waste is sustainably processed by local waste management companies, eliminating harmful practices such as dumping or burning.


Acknowledging the collective responsibility in combating plastic pollution, CLEAR RIVERS is actively collaborating with local communities and organizations to raise awareness about the urgency of the issue. In the words of our Founding Director, Ramon Knoester:


"Capturing plastic is just one part of the solution. By addressing the root causes through our education and awareness program, we strive to create lasting change. Within the next decade, our aim is to achieve a plastic-free Ambon."

We want to extend our gratitude to the AFAS Foundation, our invaluable financial supporter, who will be actively involved in the two-year initiative to make Ambon plastic-free. Gerben Eversdijk, Director of the AFAS Foundation, emphasizes the significance of addressing plastic pollution and the benefits it can bring to communities. Eversdijk highlights,

"The harmful effects of plastic litter on the environment are well-known to everyone. It is imperative that we take action. Through the implementation of Litter Traps and the educational program, we adopt a comprehensive approach that promotes community well-being, ensures a healthier environment, and benefits the local fishing industry. Furthermore, it contributes to the development of tourism and generates additional income for the local community. We are proud to support this impactful project. Our dream is to make the entire Ambon Bay plastic-free in collaboration with CLEAR RIVERS."

By working hand in hand with various partners and passionate individuals, we are making significant strides toward realizing a plastic-free Ambon. Together, we can create a cleaner, healthier, and more sustainable environment for all.


We are delighted to announce the inspiring collaboration behind River Fashion! At CLEAR RIVERS, recycling is a core pillar, and we are thrilled about this project. River Fashion combines fibers from collected plastic with sustainable cotton, creating a beautiful blend. The buttons, made from 100% river plastic, add a unique touch.


Our heartfelt appreciation goes out to everyone involved in making this remarkable achievement in fashion and recycling possible: Hanneke Siebelink from Míramé', Saxion Hogeschool, AC Ter Kuile, Save Plastics, Agrofair, Polymer Science Park, and Veolia Nederland. Your dedication and expertise have truly made a difference.

The Recycled Park by our Rotterdam office is a thriving nesting ground for birds during the spring and summer seasons. Egyptian geese, Canadian geese, Moorhens, Coots, Great Crested Grebes, Grey Herons, and others make it their chosen nesting site.


Excitingly, a swan couple has recently hatched four adorable babies at our floating park! This remarkable event showcases the success of our innovative structure, made entirely of recycled plastics, in nurturing urban biodiversity and providing a safe haven for nesting birds.
