Incinerators are a source of energy, with the combustion process delivering steam that can be used to generate electricity. While incinerators may reduce the volume of solid waste, they do not eliminate waste entirely and create toxic by-products such as fly ash, which contains highly poisonous substances like dioxins and heavy metals. These toxic substances can escape into the air, water, and food supply near incinerators, causing adverse health effects for nearby populations, including an increased risk of cancer, birth defects, and respiratory diseases. In addition, the ash and sludge produced by incinerators are often deposited in landfills, which can break down and release these toxins into nearby waterways.

Incinerators create toxic fly ash, which can contaminate waterways
Incinerators are a waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. While incinerators are touted as a safe process that eliminates waste, allows for robust recycling programs, and generates renewable energy, they are not without their drawbacks. One of the major concerns with incinerators is their production of toxic fly ash, which can contaminate waterways.
Fly ash is one of the by-products of trash incineration, including bottom ash, combustion gases, air pollutants, wastewater, wastewater treatment sludge, and heat. Fly ash is the lighter form of ash that is produced during incineration, and it can more easily escape from the incinerator's stack and smokestacks. It contains high concentrations of toxic compounds, including dioxins, heavy metals (such as lead, mercury, cadmium, and arsenic), and "forever chemicals" like PFAS. These toxic substances can have serious health impacts on nearby communities, including an increased risk of cancer, birth defects, and respiratory diseases.
The toxic fly ash produced by incinerators is often deposited in landfills, and it can leach out as landfill containment systems break down. This leachate, or garbage juice, can contaminate groundwater and rivers, posing a threat to both the environment and human health. For example, in Massachusetts, the company Wheelabrator was fined for releasing contaminated water and ash sludge into local waterways and wetlands at its three incinerators. Additionally, the expansion of toxic ash landfills in New England has been criticized due to the risk of pollutants running off into important waterways, such as the Quinebaug River in Connecticut.
The impact of incinerator-produced fly ash on waterways is a serious environmental and public health concern. While incinerators may seem like a convenient solution for waste management, the toxic fly ash they produce can have far-reaching consequences for nearby communities and natural resources. To protect the environment and public health, alternative waste management solutions, such as recycling and waste reduction, should be prioritized over incineration.
To address the issue of incinerator-related waterway contamination, several actions can be taken. Firstly, stricter regulations and legislation are needed to hold incinerator companies accountable for properly treating and disposing of toxic ash. This includes implementing effective testing requirements for toxic contaminants in landfill discharge. Secondly, investing in recycling facilities and waste reduction technologies can help reduce the amount of waste that ends up in incinerators, thereby decreasing the production of toxic fly ash. Finally, communities, especially those disproportionately affected by incinerator pollution, need to be empowered to advocate for their health and protection of their local environment.

Air pollution control devices don't eliminate pollutants, which end up in landfill
Incinerators are a waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. The burning of trash has been shown to have adverse effects on the health, environment, and economy of many communities.
Air pollution control devices, such as air filters, are used in newer incinerators to capture and concentrate some of the pollutants produced during the burning process. However, it is important to note that these devices do not eliminate the pollutants entirely. Instead, the captured pollutants are simply transferred to other by-products, such as ash and wastewater treatment sludge, which are then deposited in landfills.
The problem with this approach is that the landfill containment systems can break down over time, leading to the release of these toxic by-products into the surrounding environment, including groundwater and rivers. This can have severe ecological and health consequences, as the pollutants can contaminate water sources and harm both wildlife and humans.
Furthermore, air filters still allow many hazardous emissions, such as ultra-fine particles, to escape into the air. These fine particles are unregulated and particularly harmful to human health, contributing to respiratory and cardiovascular diseases, including lung cancer and asthma. They can also travel long distances, affecting areas far removed from the incinerator site.
To truly address the issue of waste management and reduce pollution, it is essential to focus on producing less waste, reducing plastic usage, and adopting effective recycling methods. Alternative technologies, such as autoclaving, microwave disinfection, steam sterilization, and thermal desorption, offer safer and cleaner methods of waste treatment that do not rely on incineration or landfill disposal.

Incinerators emit harmful chemicals and pollutants, including heavy metals
The burning of waste generates a range of pollutants, including air pollutants such as particulate matter, heavy metals such as lead and mercury, and toxic chemicals like PFAS and dioxins. These emissions have been linked to various health issues, including lung and heart diseases, neurological disorders, and increased risks of cancers and birth defects. The pollutants released by incinerators can enter the air, water, and food supply near incinerator sites, impacting nearby communities.
Heavy metals released from incinerators are of particular concern due to their persistence and ability to accumulate in the environment. Metals tend to build up in the food chain and can cause health issues even at low doses. For example, exposure to certain heavy metals has been associated with skin lesions, neurological disorders, learning disabilities, and adverse respiratory effects. Additionally, some toxic metals, such as arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb), have been linked to potential carcinogenic, mutagenic, and teratogenic effects.
The ash produced by incinerators, known as fly ash and bottom ash, can contain high concentrations of toxic substances, including heavy metals. Improper management of this ash can lead to contamination of waterways. In one case, Wheelabrator, a company operating incinerators in Massachusetts, was fined $7.5 million for failing to properly treat and dispose of toxic ash. They were also found responsible for releasing 8,000 gallons of contaminated water and ash sludge into local waterways and wetlands.
To mitigate the impact of incinerator emissions, modern incinerators have employed air pollution control devices such as air filters. While these filters capture and concentrate some pollutants, they do not eliminate them entirely. The captured pollutants are transferred to by-products like ash and wastewater treatment sludge, which are then deposited in landfills. As landfill systems break down, these toxic substances can eventually be released into the environment, including nearby waterways.

Low-income and minority communities are disproportionately affected by incinerator pollution
Incinerators have been found to disproportionately affect low-income and minority communities. In the US, 79% of the 73 incinerators are located within three miles of low-income and minority neighbourhoods. This means that approximately 4.5 million people in the US are exposed to pollution from incinerators, with low-income and minority communities bearing the brunt of this toxic burden.
The placement of incinerators in these communities is a result of environmental injustice, where communities of colour are more likely to be located near sources of pollution, such as power plants, highways, and landfills. This is due in part to the high construction costs of incinerators, which often lead companies to rely on government subsidies, as well as the expensive operational costs of running an incinerator. As a result, incinerators are often located in low-income areas where land is cheaper.
The impact of incinerators on these communities is significant. Incinerators release harmful chemicals and pollutants, including particulate matter, heavy metals such as lead and mercury, and toxic chemicals such as PFAS and dioxins. These pollutants are linked to a range of health problems, including asthma, heart disease, lung disease, neurological diseases, cancer, and birth defects. The communities living near incinerators are already experiencing pollution from other industrial sources, and the addition of incinerator pollution contributes to the overall cumulative impacts on their health and well-being.
The issue is further exacerbated by the lack of regulation and accountability. While US incinerators typically follow rules on allowable emissions, the regulations do not take into account the cumulative burden of pollution faced by these communities. Additionally, there have been cases of mismanagement, with companies failing to properly treat and dispose of toxic ash, resulting in the contamination of local waterways and ecosystems.
The environmental and health impacts of incinerators on low-income and minority communities have led to strong opposition from environmental and environmental justice groups. These groups advocate for sustainable alternatives that improve public health and save money, rather than investing in a dying industry that perpetuates environmental injustice.

Incinerators are not efficient and cost energy to produce little compared to alternatives
Incinerators are a type of waste treatment technology that involves burning commercial, residential, and hazardous waste, also known as municipal solid waste. They are often touted as being environmentally beneficial by various industries, but incineration is a false solution that poses a threat to public health and the environment.
Firstly, incinerators are not efficient and cost energy to produce little compared to alternatives. According to the Environmental Integrity Project's report, incinerators need tons of trash to produce a maximum of 200 megawatts. There is little net gain from incinerators, and they can even be costly in terms of energy production. The process of incineration requires a significant amount of energy to operate, and the amount of waste generated does not always justify the energy expended.
In contrast, recycling and other waste prevention measures have become more viable since the 1990s. Recycling facilities produce more than twice the number of jobs provided by landfills and incinerators combined, and it is a successful business that creates real and tangible wealth. Recycling is also more energy-efficient than incineration, as it saves energy compared to the high energy requirements of incineration. Additionally, recycling puts materials back into the economic loop, preserving finite resources for future generations.
Furthermore, there are alternative technologies available that are safer and cleaner than incineration. For example, 45% of medical waste can be sterilized and reused through autoclaving, and the remaining waste can be treated through microwave disinfection and steam sterilization. Chemical treatment is another alternative, where specialized chemicals are used to neutralize and destroy hazardous components of medical waste, reducing the risk of pollution. These alternatives often require less energy and have a reduced environmental impact compared to incineration.
In conclusion, incinerators are not efficient and cost energy to produce little compared to alternatives. Recycling and other waste treatment technologies are more energy-efficient, economically beneficial, and environmentally friendly options that should be prioritized over incineration to protect public health and the environment.
