Noria develops river cleaning solutions suitable for several locations like river bends, city centers, sewer systems, or in an estuary. Their approach to jointly solving the problem reflects the contours of the Dutch polder model. Their system builds on a traditional Dutch water technique, a solution that moves as much as 95% of the floating plastic from the water to the shore. It was founded by Rinze de Vries in 2018 and operates in Delft, Netherlands.
