Although many people believe that their plastic waste is managed effectively and properly through recycling, a good amount of exported plastic waste goes to nations that lack proper waste management facilities. Sometimes, plastic, which is considered recyclable, is burnt openly, thereby emitting dangerous gases and particulate matter into the atmosphere. Recycling of plastics, exportation of plastic wastes, international recycling of plastics, pollution by plastics, open burning of plastics, threats to public health, air pollution, waste management, and environmental pollution, especially due to global plastic wastes, have been increasingly associated with each other in an emerging environmental crisis.
The hidden reality of exported plastic waste: Where does it go
Over the years, developed countries have been disposing of plastic waste in poorer nations to be processed. It is intended that the waste be processed and eventually reentered into circulation. However, a great deal of these materials cannot be properly recycled because of contaminants and mixed materials.When recycling facilities become overwhelmed, plastic waste is often dumped, buried or burned. Researchers studying global waste management have identified open burning as one of the most overlooked forms of plastic pollution. Dr Therese M. Karlsson, Doctor of Philosophy, Science and Technical Advisor at the International Pollutants Elimination Network (IPEN), describes the open burning of plastic waste as “highly prevalent across the globe” and notes that the real amount of plastics and plastic wastes, and of toxic chemicals contained in plastics and wastes that move globally via trade, is likely to be even higher. As plastic production increases, plastic waste will also skyrocket. Estimates show we will produce 26 billion tonnes of plastic waste by 2050. We cannot manage this level of waste generation sustainably, and without global policies to reduce plastic production, there will continue to be an unequal exchange of plastic waste from high-income countries to non-high-income countries.The issue extends beyond litter and landfill sites. Once plastic is burned, pollutants are released directly into the atmosphere, affecting both local communities and wider ecosystems.
How burning plastic affects public health
The health consequences of burning plastic are becoming increasingly clear. Studies show that when plastic is burnt, a complex composition of poisonous materials such as dioxins, furans, heavy metals, and fine particles is emitted into the air.In their study, “Open Burning of Plastic Waste: An Urgent Global Health Issue,” scientists claim that the contaminants that are emitted while burning plastic may still remain active even after all the smoke and odour disappear.These pollutants may affect not only the air but also the lungs, blood, and the surrounding environment. Exposure to these pollutants can lead to respiratory infections, heart disease, developmental disorders, and various other diseases.Joseph Hoover, who holds his doctorate from the University of Arizona and is also part of the core faculty of the Indigenous Resilience Centre, speaking in an interview with Susan Cosier of the National Institute of Environmental Health Sciences, also notes that burning plastic wastes at home has a great impact on air pollution and health, especially in regions where there is no waste collection system.It is estimated that about two billion people across the globe do not have any waste collection facilities within reach.
Why open burning remains a global environmental challenge
An additional reason why open burning continues despite efforts to address the issue is that it can sometimes turn into an informal means of waste disposal because of insufficient infrastructure. Communities may lack other options if waste collection services are either sporadic or nonexistent altogether.The aforementioned study on waste management practices in India, Indonesia, the Philippines, and Zambia noted that plastic burning is often considered a pragmatic method for reducing waste quantity despite insufficient awareness about its long-term effects on health.Open burning of plastic waste can lead to severe risks for both occupational and general populations because of the inhalation of contaminated smoke by waste workers and nearby communities. Aerosols created through the burning of plastic waste are more toxic than aerosols produced in most other combustion processes.
Improving recycling and reducing plastic pollution
According to specialists, the solution to the problem is not simply about getting people to recycle. Domestic recycling processes, less plastic production, better waste management practices, and increased transparency on exports of plastic waste must all be considered.The specialists point out that the issue of open burning must be addressed in international plans related to plastic pollution, since currently this area is overlooked.Consumers are reminded by the study results that putting plastics in a recycling bin is just the first step. Further fate will depend on management systems. Without appropriate recycling infrastructure and proper waste management regulations, plastics which were intended for recycling may end up contributing to pollution anyway.
