Trash Disposal: Burying Vs Burning, Which Is Worse?

Burning trash is a common method of waste disposal, especially in rural areas. It is often considered a more cost-effective and environmentally friendly alternative to burying trash in landfills, as it reduces trucking waste to distant landfills and generates energy. However, burning trash releases harmful pollutants into the air, water, and soil, posing significant risks to human health and the environment. These pollutants include carbon dioxide, mercury, lead, dioxins, and toxic ash. On the other hand, landfills emit methane and toxic leachate, contributing to greenhouse gas emissions and water pollution. While both methods have their drawbacks, the debate around burning versus burying trash highlights the complex challenges of waste management and the need for sustainable solutions that protect public health and the environment.

Burning trash releases harmful chemicals and pollutants into the air

The smoke from backyard burning, which is the burning of household trash by residents on their property, is released directly into the atmosphere without treatment or filtration. This smoke can contain synthetic chemicals from coated papers, plastics, and other commonly discarded materials. These pollutants can settle in water bodies, soil, and groundwater, contaminating the environment and entering the human food chain through crops, livestock, and meat, fish, and dairy products.

The health effects of exposure to smoke from burning trash include eye and nose irritation, coughing, nausea, headaches, and dizziness. People with heart and lung conditions are at an increased risk of experiencing these symptoms, and smoke can trigger asthma attacks. Repeated exposure to the pollutants in burn barrel smoke can lead to an increased risk of developing chronic health issues.

The carbon dioxide emitted from burning trash contributes to greenhouse gas emissions, impacting global warming. While the amount of carbon dioxide released from trash burning is dwarfed by other sources on a global scale, such as cars and power plants, it can be a significant contributor in certain countries and regions, warranting further attention and study.

Overall, the burning of trash releases a multitude of harmful chemicals and pollutants into the atmosphere, posing risks to both the environment and human health. The pollutants can contaminate the air, water, and soil, and the toxic chemicals released have been linked to adverse health effects and an increased risk of chronic illnesses.

Burning trash can be cheaper and more convenient than burying it

Burning trash is often considered a cheaper and more convenient alternative to burying it. This is especially true in areas with limited space and rising costs of landfilling, such as New Hampshire, where burning solid waste is seen as a more economical and environmentally friendly option.

Burning trash can reduce the need for trucking waste to distant landfills, thus lowering fuel costs and vehicle emissions. It is also argued that incineration shrinks waste and can produce heat and electricity, making it a seemingly attractive option for waste management. Additionally, burning trash can be seen as a quick and easy way to dispose of garbage, especially in rural areas where access to landfills or recycling centers may be limited.

In some cases, burning garbage may be the only feasible option for waste disposal. For example, in developing regions, backyard burning may be the most accessible method of waste management. Similarly, in the 1980s, the United States experienced a garbage crisis, with municipal dumps closing and landfills overflowing. This led to the construction of incinerators as a solution to manage the increasing waste.

However, it is essential to consider the environmental and health impacts of burning trash. Incineration releases thousands of pollutants into the air, soil, and water, including toxic chemicals such as mercury, lead, and dioxins. These pollutants can have severe consequences for nearby communities and the broader public. Additionally, incinerators can be expensive to build and maintain and they may divert attention and resources away from recycling and waste reduction initiatives.

While burning trash may offer certain advantages in terms of cost and convenience, it is crucial to weigh these benefits against the potential risks to human health and the environment. Exploring sustainable alternatives, such as waste reduction, recycling, and reusing materials, should be a priority to minimize the negative impacts of waste management practices.

Burning trash contributes to global warming and climate change

Burning trash releases harmful emissions into the atmosphere, contributing to global warming and climate change. Atmospheric scientist Christine Wiedinmyer's research revealed that burning trash pumps more greenhouse gases into the atmosphere than previously thought. According to Wiedinmyer's study, around 1.1 billion tons of waste, or over 40% of the world's garbage, is burned in open piles, emitting more pollutants than reported in regional and global inventories.

The emissions from trash burning include carbon dioxide, particulate matter, reactive trace gases, and toxic compounds. Carbon dioxide is the primary gas emitted, with an estimated 40-50% of the garbage composed of carbon. While other sources, such as cars and power plants, contribute more significantly to global carbon dioxide emissions, trash burning can be a notable source in certain countries and regions, particularly those without adequate waste management systems.

Trash incineration, a waste treatment technology, converts waste such as paper, plastics, metals, and food scraps into various byproducts, including ash, combustion gases, air pollutants, and wastewater. Incinerators have been promoted as environmentally friendly solutions, but they release thousands of pollutants that contaminate the air, soil, and water. Additionally, the ash management process can be challenging, with cases of toxic ash and contaminated water being released into local waterways and wetlands.

The composition of waste varies between countries, with organic waste, including food and green waste, comprising about 65% of waste generated globally. Lower-income countries tend to have a higher proportion of organic waste, while higher-income countries have more paper, plastics, and glass waste. By 2050, it is estimated that global waste generation will increase by 73%, with the most significant increases in Sub-Saharan Africa and South Asia.

The waste sector is one of the top three methane emitters, contributing about 20% of human-driven methane emissions. Methane is a potent greenhouse gas, with over 80 times the warming potential of carbon dioxide in the short term. Reducing methane emissions from waste is crucial for slowing global warming and meeting long-term climate goals.

In conclusion, burning trash releases significant amounts of greenhouse gases and pollutants, contributing to global warming and climate change. It poses risks to the environment and public health, and the emissions are often not adequately reflected in official inventories. Addressing this issue and improving waste management practices, especially in developing regions, are essential steps in mitigating climate change.

Burying trash in landfills has environmental consequences, including the emission of methane

Burying trash in landfills has significant environmental consequences. One of the most pressing concerns is the emission of methane gas, a greenhouse gas that is far more potent than carbon dioxide in absorbing the sun's heat. Methane is released as organic waste decomposes anaerobically in landfills, and it has a substantial impact on global warming and climate change. Landfills are the third-largest source of human-related methane emissions in the United States, contributing about 14.4% of these emissions in 2022.

While some landfills have systems to capture methane for energy production, there are still challenges with gas capture systems going offline or being improperly managed, leading to massive leaks. The Environmental Protection Agency (EPA) has been criticized for using outdated and flawed methods to estimate landfill methane emissions, which may result in underestimating the actual levels.

In addition to methane, landfills also produce carbon dioxide, water vapor, and trace amounts of other gases, which can contribute to climate change and smog if not controlled. The creation of landfills often involves destroying natural habitats, and the average landfill size of 600 acres has led to a significant loss of wildlife habitat in the United States.

Furthermore, landfills can pose health risks to nearby communities. Emissions from landfills contain toxins such as mercury and ammonia, which can cause eutrophication or a lack of oxygen in nearby water sources, creating "dead zones" where animals cannot survive. Studies have also linked proximity to hazardous waste landfill sites with an increased risk of congenital malformations in children.

The environmental consequences of burying trash in landfills extend beyond methane emissions, highlighting the importance of exploring alternative waste management strategies and reducing, reusing, and recycling whenever possible.

Incineration technologies attempt to reduce the environmental impact of burning trash

Burning trash releases a significant amount of carbon dioxide and other pollutants, which can be detrimental to human health and the environment. It contributes to global warming and air pollution, particularly in developing regions where open burning of waste is common. Incineration, a waste treatment technology that involves burning waste, has been touted as a solution for eliminating waste and generating energy. However, incinerators also release thousands of pollutants and toxic ash that contaminate the air, soil, and water.

To reduce the environmental impact of incineration, advancements in incineration technologies and waste management strategies are being explored. Here are some examples:

Intelligent Technologies for Clean Incineration

Municipal solid waste incineration (MSWI) systems aim for clean incineration by employing intelligent technologies. The selection of an appropriate site for incineration is critical to minimizing environmental impact and preserving natural resources. In-plant operation control, intelligent monitoring systems, and pollutant control technologies are utilized to achieve efficient and clean operations. Dynamic adjustment of waste incineration parameters and real-time monitoring of gaseous and particulate pollutants help optimize the treatment of heterogeneous wastes.

Integration of Internet of Things (IoT) with Bioleaching and Anaerobic Digestion

The integration of IoT technologies with bioleaching (BL) and anaerobic digestion (AD) enhances resource recovery from sewage sludge (SS). BL extracts heavy metals through microbial metabolism, while AD offers an efficient method for biogas production and nutrient recovery. IoT-based solutions enable real-time monitoring and optimization of environmental factors, minimizing adverse effects and maximizing resource recovery. They also reduce operational costs, energy consumption, and environmental impacts through predictive maintenance and process automation.

Advanced Incineration Technologies

Some advanced incineration technologies, such as "waste-to-energy" incinerators, aim to convert solid waste into synthetic gas or oils followed by combustion. These include high-heat technologies like gasification, plasma arc, and pyrolysis, also known as "conversion" technologies. However, these technologies are expensive to build, polluting, and unsustainable compared to Zero Waste programs.

Green Technologies in the European Union (EU)

EU member states have shown a commitment to reducing their reliance on incineration by adopting green technologies and environmentally conscious taxation policies. They aim to harmonize industrial emissions management with efficient waste disposal, tailoring waste management strategies to accommodate diverse consumption patterns and unique circumstances within individual member states.

While incineration technologies attempt to reduce the environmental impact of burning trash, it is important to note that they are not a perfect solution. The focus should also be on reducing, reusing, and recycling waste to minimize the need for incineration in the first place.
