Blue Barriers - A system to reduce plastic pollution in our oceans and generate wealth for local communities

The Blue Barriers are a simple yet effective solution to solve Ocean plastic pollution by collecting it from rivers before it even gets to the Ocean.

It simply uses the water flow to accompany plastic litter towards a collection basin on a side of the river, where it can easily be removed and directed to recycle. They are built in 2 or more modules to allow boat navigation and guarantee no impact on river life. Designed to resist to any river condition thanks to stainless-steel cables structure, they represent a permanent solution to dramatically reduce the quantity of plastic reaching the Oceans. The Blue Barriers are able to collect nearly 100% of that plastic in standard conditions and 92% in flooding conditions (tested at the Hydrodynamic Lab of the University of Florence), protecting essential river and marine ecosystems, improving the quality of life of the local population, reducing the risk of flooding due to waste mismanagement and eventually protecting the long term potential of important industries like tourism and fishing.

Key features

  • If installed on the 20 most polluting rivers worldwide the Blue Barriers would:
  • Prevent from 1M tons of macroplastic to enter the Oceans every year
  • Prevent the release of about 800K tons of CO2 to the atmosphere every year


  • A payback varying between 2 to 15 years, depending on the quantity of plastic collected and the size of the river
