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.

- To Tackle Plastic Pollution We Need to Know Where It’S Coming from
To tackle plastic pollution we need to know what rivers these plastics are coming from. It also helps if we understand whythese rivers emit so much. Most of the world’s largest emitting rivers are in Asia, with some also in East Africa and the Caribbean. In the chart we see the ten largest contributors. This is shown as each river’s share of the gl...
Asia accounts for 81% of global plastic inputs to the ocean
We’ve looked at the role of individual rivers, but how do these aggregate at the regional and country-level? Which countries emit the most plastic to the ocean? In the chart we see the breakdown of global plastic inputs to the ocean by region. 81% of ocean plastics are emitted from Asia. The fact that a disproportionate amount of plastic pollution comes from Asia is consistent with previous research. Earlier studies estimated its share in 2010 was 86%.5 This should also not surprise us given...
More than one-third of ocean plastic inputs come from the Philippines
The distribution of plastic inputs is reflected on the world map. There we see each country’s share of global plastic emissions. The Philippines accounts for more than one-third (36%) of plastic inputs – unsurprising given the fact that it’s home to seven of the top ten rivers. This is because the Philippines consists of many small islands where the majority of the population lives near the coast. But it’s an important update on our previous understanding of where China and India were thought...
We can understand what determines each country’s contribution through three steps. First, the amount of plastic waste that each country generates in the first place. Rich countries produce much more plastic waste per person than poorer countries. Most produce 0.2 to 0.5 kilograms per person per day.8 This compares to 0.01 in India or 0.07 kilograms...
Identifying where plastic emissions are coming from really matters for how we tackle it. Rich countries emit very little – this means domestic strategies to reduce plastics in these countries will not make much difference to ocean plastics. What rich countries cando is support low-to-middle income countries in improving waste management infrastruct...
Jun 3, 2021 · Between 2017 and 2020, the study examined more than 1,600 rivers worldwide which together make up 80 percent of the total inflow of plastic into the world's oceans. The amount of plastic flushed ...
The Ciliwung River basin on Java, which is much smaller than the Rhine River basin (respectively, 591 km 2 versus 163,000 km 2) and with less total generation of plastic waste (respectively, 19,590 MT year −1 versus 34,440 MT year −1), emits two orders of magnitude more plastic into the ocean (308 MT year −1 observed and 205 MT year −1 modeled for the Ciliwung River, and 3 MT year −1 ...

Feb 19, 2024 · Another important finding is the difference between smooth and rough ground surfaces. In windy conditions, plastic trash was 1.5 times more likely to start moving on the smooth paved surface than on the rougher grass. In the rain, certain plastic items were 6 times more likely to move on paved surfaces than on grass.

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 ...
