   Apr 30, 2021 · The publication sheds new light on where and how much plastic flows into the oceans via rivers. With the help of new measurements and modeling, the study shows that 1000 rivers shed almost 80% of plastic emissions. This number is 100 times more than the 10 rivers that were previously thought to be responsible for most of the pollution.

   Feb 19, 2024 · To rid the world’s oceans of plastic, The Ocean Cleanup intercepts river plastic to stop the leakage alongside cleaning up legacy plastic in oceans. To help us target our river interception towards the most polluted places, we develop and refine global river models. Such simulations estimate the amounts of plastic that end up in rivers, and ...

   Rivers are a major source of plastic waste in the oceans. We estimate that 1000 rivers, represented by the red dots, are accountable for nearly 80% of global annual riverine plastic emissions, which range between 0.8 – 2.7 million metric tons per year, with small urban rivers amongst the most polluting. The remaining 20% of plastic emissions ...

   How much plastic waste enters the ocean each year?

   • Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total.

   Are rivers causing ocean plastic pollution?

   • Rivers are the primary sources of plastic in the oceans. These new findings indicate that ocean plastic pollution is caused by a greater number of small and medium-sized rivers, defined by a set of geographic factors that determine the highest contribution to the inflow of plastic into our oceans.

   Over the next 70 years, however, annual production of plastics has increased nearly 230-fold to 460 million tonnes in 2019. Even just in the last two decades, global plastic production has doubled. The world produces around 350 million tonnes of plastic waste each year. That means 0.5% of plastic waste ends up in the ocean.
