Incineration's Air Pollution: What's The Real Damage?

Incineration is a waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. While it is often touted as a safe and environmentally friendly alternative to landfills, the reality is that incineration releases harmful chemicals and pollutants into the air, soil, and water. These pollutants include particulate matter, nitrogen oxides, sulfur dioxide, lead, mercury, dioxins, and furans, which have serious public health effects such as increased cancer risk, respiratory illness, and cardiovascular disease. The impacts of incineration are far-reaching, with persistent organic pollutants travelling long distances and building up in people and wildlife, causing detrimental health effects. With the evolution of waste-handling options, such as composting and recycling, incineration is becoming an increasingly obsolete and poor waste management option.

Incineration releases harmful chemicals and pollutants into the air, water and food supply

Incineration is a waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. This process releases harmful chemicals and pollutants into the air, water, and food supply, which can have detrimental effects on both human health and the environment.

The exhaust gases from incineration facilities contain many potentially harmful substances, including particulate matter, oxides of nitrogen, oxides of sulfur, carbon monoxide, dioxins and furans, metals (such as lead and mercury), acid gases, volatile chlorinated organic compounds, and polycyclic aromatic compounds. These pollutants are released into the air and can directly affect those living close to the facility through inhalation.

Furthermore, these pollutants can also contaminate the surrounding soil, vegetation, and water sources. Metals and other persistent pollutants can travel long distances, undergo various transformations, and pass through soil, water, or food multiple times. Dioxins, furans, and mercury are examples of such persistent pollutants, and incinerators have been found to contribute significantly to their emissions. Fish consumption, for example, is the major pathway through which humans are exposed to mercury, while meat, dairy, and fish are potential pathways for dioxin and furan exposure.

The impact of incineration is far-reaching, with emitted substances considered persistent organic pollutants that do not break down, move across the globe, and accumulate in people and wildlife, causing harm to their health. Toxins like PFAS, dioxins, and mercury compounds have been detected in the environment, people, and marine mammals in the Arctic, far removed from any industrial sources. Studies have also linked proximity to waste incineration to increased risks of cancers, birth defects, and other adverse health outcomes.

While air pollution control devices can help capture and reduce some of the pollutants emitted by incinerators, they do not eliminate them entirely. Additionally, these devices are not always optimally maintained or operated, and even well-run incinerators can contribute to local pollution and health risks. Ultimately, incineration releases harmful chemicals and pollutants that enter the air, water, and food supply, posing risks to both the environment and human health.

Incineration facilities emit gases containing potentially harmful substances, including particulate matter, oxides of nitrogen, and carbon monoxide

Incineration is a waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. The process of incineration converts waste into bottom ash, fly ash, combustion gases, air pollutants, wastewater, and heat.

The impact of incineration facilities on air pollution can be influenced by the use of air pollution control devices. For instance, airborne particles can be captured using electrostatic precipitators, fabric filters, or wet scrubbers. Similarly, oxides of nitrogen can be partially controlled through combustion-process modifications and the injection of ammonia or urea through selective catalytic or non-catalytic reduction methods. These methods help reduce the emissions of pollutants from incineration facilities.

While the use of control devices can mitigate the impact, it is important to note that incinerators still release pollutants into the air, soil, and water. These pollutants can have both local and far-reaching effects. People living close to incinerator facilities may be directly exposed to contaminants through inhalation or indirectly through the consumption of food or water contaminated by the deposition of pollutants. The impact of incineration on air quality and public health is a concern, especially in environmental justice communities, where a significant number of incinerators are located.

In summary, incineration facilities emit gases containing harmful substances, including particulate matter, oxides of nitrogen, and carbon monoxide, among others. The emissions from these facilities have the potential to cause air pollution and adverse health effects, particularly in vulnerable communities located near incinerator sites. While control measures can help reduce emissions, the release of pollutants from incineration facilities remains a challenge in the pursuit of improving air quality and protecting public health.

Incineration disproportionately affects low-income communities and communities of colour

Incineration is a process that involves burning waste, which releases harmful chemicals and pollutants into the air, water, and food supply near incinerators. These pollutants include particulate matter, heavy metals such as lead and mercury, and toxic chemicals like PFAS and dioxins. While there is limited epidemiologic data specifically linking incinerator emissions to health effects, one study found an association between air pollution from incinerators and detrimental effects on lung function in primary-school children.

The placement of incinerators is not random but is influenced by socioeconomic and racial factors. Corporations, regulatory agencies, and local planning boards have been criticized for targeting low-income communities and communities of color when siting polluting facilities, including incinerators. This pattern has been attributed to structurally racist policies such as segregation and expulsive zoning, as well as the historical discrimination that communities of color have faced in housing, education, employment, and healthcare. As a result, these communities are more vulnerable to the cumulative impacts of multiple environmental threats, such as air pollution from incinerators, and face higher health risks.

According to a report from the Tishman Environment and Design Center, 1.6 million Americans, disproportionately low-income and minority residents, live near the country's 12 most polluting incinerators. Additionally, 79% of all municipal solid waste incinerators are located within three miles or less of communities of color and low-income communities. This pattern is not limited to incinerators but extends to other polluting facilities, such as natural gas facilities, oil refineries, and power plants, which disproportionately affect communities of color.

The environmental justice movement has brought attention to the disproportionate impact of pollution on communities of color and low-income communities. Despite federal efforts to prioritize equity in environmental initiatives, marginalized communities continue to bear the brunt of pollution, with limited resources to address the resulting health and environmental issues. The movement has also highlighted the need for stricter enforcement of environmental laws and accountability for polluters in these communities.

The impacts of incineration and pollution are far-reaching, and the release of persistent organic pollutants can have global consequences. Aging incinerator facilities further exacerbate the issue, as they become more costly to maintain or upgrade, shifting the financial burden onto local taxpayers and increasing the risk of accidents that can endanger neighboring communities. Overall, incineration disproportionately affects low-income communities and communities of color due to structural racism, socioeconomic inequalities, and the cumulative impacts of multiple environmental threats.

Incineration releases more toxic pollution than coal-fired power plants per unit of energy

Incineration is a significant contributor to air pollution. The process of burning waste releases harmful chemicals and pollutants, including particulate matter, heavy metals, and toxic chemicals, which can cause a range of health issues, from lung and heart diseases to cancer and neurological problems.

Despite industry claims that incineration is a form of "renewable" or "clean" energy, data suggests otherwise. Studies have shown that incinerators emit more greenhouse gas emissions per unit of electricity produced than any other power source. They also release a range of toxic pollutants, including dioxins, mercury, and lead, which can have detrimental effects on both human health and the environment.

Trash incinerators, in particular, have been found to emit more pollution than coal-fired power plants per unit of energy produced. A 2011 analysis by the New York State Department of Environmental Conservation revealed that the state's trash incinerators were dirtier than their coal-burning power plants in terms of emissions. While pollution controls have helped reduce mercury emissions from trash incinerators, they still release significantly more mercury than coal plants per unit of energy.

Furthermore, incinerators emit more criteria air pollutants than cleaner energy sources, such as natural gas. The inclusion of incineration in "renewable" or "clean" energy standards is counterproductive, as it diverts subsidies from cleaner energy sources. As the electric grid moves towards decarbonization, the disparities in emissions between incinerators and cleaner energy sources will only become more pronounced.

The impacts of incineration are far-reaching, with persistent organic pollutants released during waste incineration found in the environment, people, and even marine mammals in the Arctic, far from any industrial sources. These pollutants do not break down and can have long-term effects on health, making incineration a significant environmental and public health concern.

Incineration is a poor waste management option that worsens environmental inequalities and reduces incentives for more sustainable practices

The issue of environmental inequalities is complex and multifaceted. It involves the spatial distribution of environmental risks and amenities, with polluting industries often locating in areas with lower land prices and labor forces, which tend to be communities with higher proportions of racial and socioeconomic minorities. This results in these communities bearing the brunt of toxic burdens, such as air and water pollution, and having limited access to clean drinking water and sanitation facilities.

In addition to worsening environmental inequalities, incineration also reduces incentives for more sustainable practices. "Waste-to-energy" systems, for example, rely on significant waste quantities to generate energy, disincentivizing waste reduction. Recycling, on the other hand, saves more energy and avoids more greenhouse gas emissions compared to waste incineration. Composting organic materials also has environmental benefits, such as improving soil health and reducing the need for chemically derived fertilizers.

Furthermore, incineration can hinder the development of more sustainable practices. The promotion of incineration as a "green" technology through greenwashing terms like "waste-to-energy" and "chemical recycling" can mislead the public and policymakers, delaying the adoption of truly environmentally beneficial solutions. To address these issues, it is crucial to prioritize sustainable practices and address the underlying mechanisms that contribute to environmental inequalities.

To promote pro-environmental behaviors and reduce incentives for harmful practices like incineration, social influence, network connections, and trust in institutions are key factors. Internal social influence, which motivates individuals to change their perceptions and attitudes, is particularly important. Additionally, increasing connections among individuals can lead to pro-environmental actions. Trust in institutions, such as governments and companies, is also crucial in shaping policies and generating desired environmental outcomes.
