Plastic pollution is a pressing global issue, with an estimated 8 to 12 million metric tons of plastic entering our oceans annually. While high-income countries tend to generate more plastic waste per person, it is the mismanagement of waste that leads to plastic pollution. Asian countries, particularly China, Indonesia, the Philippines, Thailand, and Vietnam, have been identified as significant contributors to plastic emissions in the ocean, with a 2017 study estimating that Asian nations are responsible for 86% of plastic emissions in the ocean. Factors such as the convenience of using plastic, inadequate waste management infrastructure, and the impact of corporations' packaging choices contribute to the high levels of plastic pollution in these countries.

What You'll Learn
China, the US, and Indonesia are the top polluters
China is the world's largest producer of plastic materials, responsible for 32% of global plastic production in 2021. While the daily plastic waste per person is one of the lowest at 0.12 kilograms a day, China produces more than 231,000 tons of plastic litter each year, with a high risk of polluting surrounding rivers and oceans. China has taken steps to reduce plastic waste, banning single-use, non-degradable bags and single-use plastic straws by the end of 2020.
The US produces a significant amount of plastic waste, with an average American tossing out about 12 ounces of plastic each day in 2010, equivalent to 26 average-sized water bottles. The country generates 275,000 tons of plastic litter annually, with high-risk coastal populations contributing to the pollution of surrounding waterways and the ocean.
Indonesia is a significant contributor to plastic pollution, with its Citarum River being dubbed the most polluted river in the world due to plastic waste. Indonesia, along with other Southeast Asian countries, has become a major importer of plastic waste from other high-producing countries, contributing to the region's climate crisis.
While these three countries are the top polluters, it is important to note that plastic pollution is a global issue, and many other countries, such as India, Thailand, and Vietnam, are also significant contributors to the problem. Improving waste management strategies and reducing plastic consumption are crucial steps in tackling plastic pollution worldwide.

High-income countries generate more plastic waste
While it is difficult to pinpoint the exact country that throws away the most plastic, several sources indicate that high-income countries generate more plastic waste per person. This is despite these countries having well-managed waste streams, which result in lower levels of plastic pollution in the external environment.
A 2018 report titled "Plastic Pollution" revealed that the United States was the largest producer of plastic waste in the world in 2016, with 34.02 million tons. However, China was the largest producer of plastic waste in 2010, with 59.08 million tons, almost double that of the United States. By 2016, China had significantly reduced its plastic waste production to 21.60 million tons, a decrease of nearly 28 million tons. Despite this, the United States remained the top producer of plastic waste in 2016.
Other high-income countries that are among the top producers of plastic waste include Germany, Canada, the United Kingdom, and Japan. These countries have been criticized for exporting their plastic waste to developing nations, such as Vietnam, Malaysia, and Turkey, instead of investing in proper domestic recycling or reduction strategies.
While high-income countries generate more plastic waste per person, it is important to note that the mismanagement of waste tends to be higher in low-to-middle-income countries due to poorer waste management infrastructure. As a result, most of the plastic flowing into the oceans today comes from middle-income countries, particularly in Asia. A 2017 study estimated that Asian countries contributed 86% of plastic emissions to the ocean.
To address the issue of plastic pollution effectively, it is crucial to improve waste management strategies and reduce plastic production, especially in countries with high plastic waste generation.

Asia's rural hamlets contribute to plastic waste
Asia is the source of over half of the world's ocean plastic, with Southeast Asian nations being significant contributors to the leakage of land-based plastic waste into the seas. The top 10 countries with the highest generation of mismanaged plastics include Malaysia, Thailand, Vietnam, the Philippines, and Indonesia. These countries produce over 1.5 million metric tons of mismanaged plastics annually, with Indonesia and the Philippines ranked second and third, respectively.
The reasons for this can be attributed to the region's inadequate waste management infrastructure, the geographical spread of communities, and the high population density along coastlines. For example, in Indonesia, the difficulty and expense of formal waste collection in coastal communities have resulted in the reliance on informal workers, who collect, sort, and deliver plastic waste directly from households to recycling facilities.
Cultural habits also play a role in plastic waste generation. In countries like China and Vietnam, food and beverages are often packed directly into plastic bags, and disposable utensils are commonly used for eating and food delivery.
While high-income countries tend to generate more plastic waste per person, it is the mismanagement of waste that leads to plastic pollution. Mismanaged waste is higher in low-to-middle-income countries due to poorer waste management infrastructure. As a result, plastic waste ends up in rivers and oceans, contributing to the significant amount of plastic pollution in Asia and globally.
To combat this issue, Southeast Asian nations have taken steps to address plastic pollution. Malaysia, for instance, has implemented the "Roadmap to Zero Single-Use Plastics" and returned over 4,000 tons of plastic waste to other countries. Thailand has also restricted electronic waste imports and pledged to end plastic waste imports. Additionally, startups like Hong Kong-based The Kommon Goods produce eco-friendly lifestyle products to reduce plastic waste from disposable utensils.

Mismanaged plastic waste in low-to-middle-income countries
While high-income countries tend to generate more plastic waste per person, they also typically have better waste management systems in place. As a result, they tend to have lower levels of plastic pollution in the external environment. However, plastic waste still enters rivers and oceans, especially from coastal populations.
Mismanaged plastic waste, which is not recycled, incinerated, or disposed of in sealed landfills, tends to be much higher in low-to-middle-income countries. This is because these countries tend to have poorer waste management infrastructure. Most plastic flowing into the ocean today comes from middle-income countries, particularly across Asia. A 2017 study estimated that Asian countries contributed 86% of plastic emissions to the ocean.
China, Indonesia, the Philippines, Thailand, and Vietnam have been identified as the top five countries contributing to plastic emissions in the ocean. While China's per capita production of plastic waste is one of the lowest in the world, the country produces more than 231,000 tons of plastic litter each year, with a high risk of polluting surrounding rivers and the ocean. Similarly, the United States, which produces the second-highest amount of plastic waste, burns six times more plastic waste than it recycles, releasing harmful chemicals into the atmosphere.
The plastic waste crisis is accelerating and requires immediate action, with the most severe consequences being felt in developing countries. Strategies that are effective in high-income countries are not always suitable for low-income countries due to social, political, ecological, and economic challenges. A promising approach for developing countries is the Locally Managed Decentralized Circular Economy (LMDCE), which empowers local communities in infrastructure-limited regions to take control of their plastic waste management supply chain.

Global plastic production has doubled in the last 20 years
Global plastic production has increased rapidly since the 1950s, with a nearly 230-fold increase in annual production over the next 70 years, reaching 460 million tonnes in 2019. This trend has continued, with global plastic production surpassing 400 million metric tons in 2022. Even in just the last 20 years, global plastic production has doubled.
The world currently produces around 350 million tonnes of plastic waste annually, with an estimated 1 to 2 million tonnes of plastic entering the oceans each year. This plastic waste comes from a variety of sources, including street vendors and food delivery services that utilise plastic utensils and packaging.
High-income countries tend to generate more plastic waste per person, with the average American discarding about 12 ounces of plastic daily in 2010. The U.S. produces a significant amount of plastic litter, with 275,000 tons at risk of polluting surrounding rivers and oceans. However, despite being the largest producer of plastic waste, China's daily plastic waste per person is relatively low at 0.12 kilograms.
Asian countries have been identified as significant contributors to plastic emissions in the ocean, with a 2017 study attributing 86% of plastic emissions to this region. This is due in part to the widespread use of plastic in food packaging and transportation, as well as the lack of proper waste management infrastructure in some countries.
To address the issue of plastic pollution, it is crucial to focus on improving waste management practices, particularly in low-to-middle-income countries where mismanaged waste tends to be higher. This includes reducing consumption, increasing recycling and incineration rates, and investing in waste management infrastructure.
