The world’s growing plastic waste crisis is creating an environmental and public health problem far beyond the countries where the waste is generated. New research suggests that a significant portion of plastic waste exported for recycling is ultimately being burned in lower income countries releasing dangerous pollutants into the air and increasing health risks for local communities.
According researchers found that large volumes of plastic waste shipped from wealthier nations are ending up in countries where waste management systems are often inadequate. In many cases, open burning has become a common method of disposal, exposing millions of people to toxic emissions.
The findings come as global plastic waste production continues to surge. If current trends continue, experts warn that by 2050 the world could generate a mountain of plastic waste equivalent to a pile larger than Manhattan and taller than one and a half Empire State Buildings every year.
Plastic Burning Creates Toxic Pollution
When plastic is burned in open dumps or waste sites, it releases a mixture of hazardous pollutants into the atmosphere. These include fine particulate matter, carbon monoxide, styrene gas, hydrogen cyanide, dioxins, and polycyclic aromatic hydrocarbons.
Scientists have linked these pollutants to numerous health problems, including respiratory illnesses, cardiovascular disease, cancer, reproductive disorders, and neurological damage.
The risks do not end with air pollution. Residual ash from burned plastic can contaminate soil and groundwater with toxic chemicals and heavy metals, creating additional pathways for human exposure through food and drinking water.
Global Plastic Trade Shifts After China’s Ban
For decades China was the world’s largest importer of plastic waste, receiving around 45 percent of global plastic waste imports between 1992 and 2016.
However, China’s decision to ban plastic waste imports in 2018 dramatically changed global waste flows. As a result, exporters began shipping more waste to countries across Southeast Asia, including Indonesia and Malaysia.
Indonesia became one of the major destinations for imported plastic waste after China’s ban. Much of this waste originated from Europe, North America, and Australia.
Air Quality Worsened in Indonesia
Researchers used satellite imagery, air pollution monitoring systems, and cargo shipping data to investigate the impact of increased plastic waste imports on Indonesia.
The study found that fine particulate pollution levels near major open waste dump sites increased by an average of 3.3 percent after China’s import ban compared to expected levels based on previous years.
The rise in pollution was associated with higher estimated health risks. Researchers calculated that long-term exposure could increase mortality risks by approximately 1.5 percent for chronic obstructive pulmonary disease, 1.9 percent for lung cancer, and 3.5 percent for lower respiratory infections.
According to estimates from the World Economic Forum and the Indonesian government, nearly half of Indonesia’s plastic waste was being openly burned as recently as 2020.
Countries Tighten Plastic Waste Rules
Growing concerns over pollution have prompted several countries to strengthen regulations on imported waste.
Indonesia restricted non-hazardous waste imports to selected ports in 2021 and introduced a complete ban on plastic waste imports in 2025.
Malaysia followed with stricter regulations in 2025, allowing plastic waste imports only from countries that have ratified the Basel Convention, an international treaty governing hazardous waste movements. The United States has not ratified the convention.
The European Union has also introduced new waste shipment regulations that will prohibit exports of plastic waste to many non-OECD countries beginning in late 2026.
Recycling Alone Is Not Solving the Problem
The study highlights the limitations of relying solely on recycling as a solution to plastic pollution.
In the United States, estimates suggest that only about 5 to 6 percent of plastic waste is actually recycled. Recycling infrastructure remains limited, and many facilities lack the capacity to process growing volumes of plastic waste.
Experts argue that reducing plastic production and consumption must become a central part of the solution. Strategies include designing products that are easier to recycle, expanding reuse systems for packaging, and implementing extended producer responsibility programs that require manufacturers to bear some of the costs of managing plastic waste.
Several U.S. states, including California, Colorado, Oregon, Washington, Maine, Minnesota, and Maryland, have already adopted packaging responsibility laws aimed at reducing waste and improving recycling rates.
Global Problem Requiring Global Action
Researchers conclude that plastic waste is not simply a local disposal issue but a global environmental challenge. While wealthier countries may export waste abroad, the environmental and health consequences often fall on communities with fewer resources to manage it safely.
As international negotiations on a legally binding plastics treaty continue, scientists say reducing plastic production, improving waste management systems, and strengthening recycling infrastructure will be essential to preventing further environmental damage and protecting public health worldwide.
