The BioDesign River Cleaning Project is a modular and intelligent barrier that is positioned diagonally across watercourses to cover their entire width. Its purpose is to intercept floating and partially submerged waste before it reaches the sea. Worldwide, the majority of the ca. 40 million tonnes of plastic pollution that annually end in the oceans, originates from rivers.

Thanks to an interception efficiency of over 90%, it provides a practical and functional solution to reduce water pollution while also recovering recyclable materials. Deploying a principle similar to a series of cogs the BioDesign River Cleaning Project harnesses the force of water to move debris towards a collection point. Thanks to the specially developed design of the impellers, the system requires no energy and does not hinder the natural flow of water or the passage of wildlife.

The modular BioDesign River Cleaning system is entirely erected at the installation site: first the sections of the support structure are assembled, then the impellers are mounted, and finally the structure is lowered into the water. In the event of flooding the system automatically rises via sensors.
