Burning plastic releases harmful emissions and pollutants
Burning plastic is a major source of air pollution. It releases harmful emissions and pollutants, such as dioxins, furans, mercury, and polychlorinated biphenyls (PCBs), into the atmosphere. These toxins can cause cancer, disrupt neurodevelopment, endocrine, and reproductive functions, and interfere with hormone functions. They pose a threat to vegetation, human and animal health, and the environment as a whole. Burning plastic also contributes to climate change, as the release of hazardous halogens from Poly Vinyl Chloride pollutes the air.
The problem with incineration is that it does not solve the plastic pollution problem. Plastics will continue to pollute the environment, even if they are burned. Incineration also encourages more plastic production to replace the burned plastic, leading to a continuous rise in total emissions. Additionally, incinerators require a steady supply of waste to keep running, creating an incentive to produce more waste instead of reducing plastic consumption.
The cost of building and operating incinerators is also significantly high, making the energy produced from these facilities the most expensive. Furthermore, incinerators contribute to air emissions, releasing pollutants such as dioxins and heavy metals. These air pollutants pose health risks to communities located near plastic waste incinerators.
To address the issue of plastic waste, it is essential to focus on reducing, reusing, and recycling plastic. Community-based approaches, such as decentralized waste separation and collection, increased resource recovery, composting, and waste reduction, are healthier for the environment and create economic opportunities for waste workers. Burying plastic waste is another alternative, as it locks up unwanted carbon at a lower cost than incineration.
While burning plastic may seem like a solution to get rid of waste, it ultimately contributes to air pollution and poses risks to human health and the environment. Therefore, it is crucial to explore alternative methods of plastic waste management that do not involve burning, such as recycling and proper disposal, to prevent harmful emissions and protect the planet.

Burning plastic is an expensive process
Firstly, the financial cost of incineration facilities is high. They require expensive power generators that cost millions to build and operate. These facilities need a continuous supply of waste to keep running, which means a steady collection of waste. This makes it a demanding waste management system, and the energy produced from incineration facilities is the most expensive of all energy sources. For example, in Canada, it cost $250 to burn one tonne of waste at an incineration facility in Burnaby, BC, totalling $375,000 of taxpayers' money for 69 containers of waste.
Secondly, burning plastic is expensive in terms of its environmental cost. Plastic is made from oil and gas, and it burns hot and fast, creating a lot of heat. However, this process releases harmful pollutants and emissions into the environment, contributing to air pollution that can harm human health and the environment. Plastics, in particular, release pollutants such as dioxins, heavy metals, microplastics, bisphenols, and phthalates when burned. These toxins can disrupt neurodevelopment, endocrine, and reproductive functions and pose a health risk to communities located near plastic waste incinerators.
Additionally, burning plastic encourages more plastic production to replace the burned plastic, leading to a continuous cycle of burning and producing plastics that benefits the plastics industry but harms the environment. With only eight per cent of plastic waste being recycled in Canada, it is clear that the focus should be on reducing plastic consumption and increasing recycling efforts rather than burning plastic.
In summary, burning plastic is an expensive process that has negative financial and environmental implications. It contributes to air pollution, endangers human health, and perpetuates the linear plastics economy. Therefore, it is essential to explore alternative solutions, such as reducing, reusing, and recycling plastic waste.

Burning plastic encourages more plastic production
Burning plastic is a highly prevalent practice across the globe, especially in low- and middle-income countries where waste management systems are inadequate. While burning plastic can generate energy, it also has significant drawbacks, including air pollution and negative impacts on human health.
One of the main issues with incineration is that it does not address the root cause of plastic pollution. As long as plastic producers continue to increase their output, the challenge of collecting and managing plastic waste will persist. Incineration can even incentivize greater plastic production to replace the burned plastic, perpetuating a linear plastics economy that benefits the industry's profits.
The high cost of building and operating incinerators is another concern. These facilities require substantial investments in expensive power generators and a continuous supply of waste to remain operational. This can create a cycle where communities are pressured to generate enough waste to feed the machines, rather than focusing on reducing plastic consumption and promoting recycling.
Additionally, burning plastic releases toxic pollutants such as microplastics, bisphenols, and phthalates, dioxins, acid gases, and heavy metals. These emissions pose risks to the health of nearby communities and contribute to environmental degradation. While modern waste-to-energy plants employ technologies to capture these pollutants, there are concerns about proper operation and emissions control, especially in countries with lax environmental regulations.
To break free from the cycle of burning and producing plastics, it is essential to transition to a circular economy. This involves reducing plastic production, increasing recycling efforts, and promoting the reuse of materials. While pyrolysis, a technology that converts plastics into feedstock for new high-quality materials, can be considered part of a circular economy, it does not address the underlying issue of high plastic demand. Therefore, the most effective solution lies in decreasing plastic consumption and transitioning to alternative materials.

Burning plastic affects air quality and human health
The impact of burning plastic on air quality is further exacerbated by the inefficient energy generation of incineration processes. Incinerators produce electricity with only 25% heat efficiency, compared to 55% for new gas-fired power stations. This inefficiency contributes to increased pollution and encourages a continuous cycle of plastic production and incineration, rather than incentivizing plastic reduction and recycling. The high cost of incineration facilities and their demand for a steady waste supply reinforce this cycle, benefiting the plastics industry economically while negatively impacting the environment.
The problem of burning plastic waste is particularly acute in low- and middle-income countries, where plastic is readily available and affordable. In Guatemala, for example, 71% of households burn waste as the primary means of disposal. This practice contributes to both indoor and outdoor air pollution, which is a significant risk factor for nearly seven million premature deaths globally. The lack of solid waste collection services and proper waste management systems in many parts of the world exacerbates the issue, leading to open dumping and frequent waste burning.
To address the issue of burning plastic and its impact on air quality and human health, it is crucial to focus on waste management solutions that reduce, reuse, and recycle plastic materials. Projects such as the Center for Native Environmental Health Equity Research's solid waste disposal project aim to find alternatives to burning plastic in household fires. By promoting waste reduction, reusing, repurposing, and recycling, these initiatives strive to minimize the negative consequences of burning plastic on the environment and public health.
Additionally, burying plastic waste has been proposed as a potential alternative to burning. While it does not eliminate the carbon emissions associated with plastic, it contains the carbon and prevents the spread of toxic gases through the atmosphere. However, burying plastic waste is not without its challenges, as it requires careful consideration of disposal methods to avoid contaminating water sources and the surrounding environment. Overall, the most effective solution lies in reducing plastic consumption and transitioning to a circular economy, minimizing the need for incineration and its detrimental effects on air quality and human health.
