Recent research from the Universities of Bonn and Tübingen indicates that waste levels in the Rhine are 40 times higher than previous estimates, with approximately 53,000 large pieces of debris flowing toward the North Sea daily. 

In response, the annual ‘RhineCleanUp’ initiative has mobilized tens of thousands of volunteers to collect waste from the banks of the Rhine, Ruhr, Lippe, and Niers rivers in Germany. While previous years have seen the collection of hundreds of tons of debris—including plastics and clothing—organizers have issued a specific warning for this year due to low water levels. Receding waters may expose unexploded wartime munitions, posing a danger to participants.
