A start-up has invented a “cleaner buoy” that redirects and collects waste into rivers with water power

In a report published by EarthWatch Europe, we found that 80% of the plastic waste that goes into the oceans gets there through rivers that come to dump themselves in them … That’s why experts believe that we must act upstream, it is to tell the rivers and streams to try to thwart the problem. The plastic wastes found in the ocean are mostly plastic bottles (14%), food packaging (12%) and cigarette butts (9%), the others are cotton swabs, food boxes, straws and cups. In an attempt to combat this plastic pollution by preventing it from reaching the oceans, an Italian start-up, Mold, has invented a system of floating buoys that redirect waste. , but lets boats and fish get through. Presentation.

Who Cleans the River?

Vanni Covol, is the CEO and owner of the company Mold that developed this concept. He is also the owner of the patent pending River Cleaning. Thanks to its ingenious river pollution control system, he received the Leone D’Oro of Venicea prize that rewards the best innovations in the country. Alex at Andrea Citton, were the founders of River Cleaning. Their collaboration with the inventor makes it possible to develop his wonderful project and grow it over and over again.

The system for rivers, River Cleaning

This concept consists of several floating elements that look like buoys. They are arranged diagonally in the waterway and can block plastic waste and direct it to shore. thanks to their rotating underwater system. Floating buoys are scalable, it is possible to adapt to the size of the river, to the flow or to the flow of the river with equipment. In addition, they are designed to allow themselves to be carried by the passing of a boat … So, when a boat “crashes” into a buoy, it carries, passes, and the buoy repositions itself afterwards.

How does this work?

The buoys are 100% autonomous and turn thanks to the current. The bottom of the buoy forms a kind of helix that, as it turns, directing garbage ashore where it can be picked up. No other energy but the force of the current is needed for River Cleaning to work, so it does not exist no impact on the environment or the ecosystem: the fish can continue on their way, without any problems!

“Current solutions use boats with drainage systems, net systems or barriers that temporarily block the way to the river. Each installation requires specific resources and analysis, leading to high costs; it is also very difficult to make permanent installations, precisely because of the inconveniences involved. The solution we have studied is a solution with very low environmental impact, modular and adaptable to any waterway. As part of the study for this project, physical simulation tests were conducted using software, and prototypes were developed and tested to verify their functionality. River Cleaning

The fuel system

River Cleanup doesn’t stop at fighting plastic waste! Another form of “buoy” was developed: this new innovative system could soon make it possible to proceed in the same way as with plastics, but of the oils and fuel thrown into the rivers. A parallel Plug-in will be included in the original system with several possibilities. River Oil, that’s its name, could be an additional module consisting of absorbent sponges, or more sophisticated, a suction and filtration system installed in the center of the buoy. The River Cleaning system can be a great solution for cleaning rivers and streams … We really hope it will be installed in many places around the world!
