Industrial Facilities: Major Sources Of Air Pollution

Industrial facilities are a major source of air pollution, emitting harmful substances such as nitrogen oxide, ammonia, mercury, and carbon dioxide. These pollutants are released into the air through various industrial activities, including power generation, waste treatment, and manufacturing processes. The impact of these emissions on the environment and human health is significant, contributing to climate change and causing serious health conditions such as asthma, bronchitis, cancer, and heart failure. Industrial air pollution disproportionately affects communities of color and low-wealth areas, leading to unfair health and economic burdens. To address this issue, organizations like the Clean Air Council work to reduce air pollution from industrial facilities and advocate for policies that prioritize public health and the environment.

Oil and gas operations

The health impacts of oil and gas air pollution are significant, with a study finding that in 2016, pollutants from the industry, such as nitrogen oxide, fine particulate matter (PM2.5), and ozone, led to 7,500 premature deaths, 410,000 asthma attacks, and 2,200 new cases of childhood asthma in the US. These impacts were felt in areas with high oil and gas production, like Texas, Pennsylvania, and Colorado, but also in states with minimal oil and gas activity, demonstrating the need for comprehensive regulatory action.

The Clean Air Council advocates for a rapid transition away from natural gas and single-use plastics, as well as improved recycling and the development of non-fossil fuel-based alternatives. They also work to prevent hazardous waste from the natural gas, plastics, and chemical industries, which can create significant air pollution during disposal. The US EPA has proposed revisions to the Clean Air Act to reduce methane and other harmful emissions from the oil and gas industry, recognizing the sector's contribution to climate change and public health risks.

It is important to note that the impacts of oil and gas air pollution extend beyond the direct emissions from combustion. The full life cycle of oil and gas, including extraction, processing, transportation, and end-use, contributes to the overall environmental and health consequences. Strategies focusing solely on end-pipe pollution controls address only a part of the problem, and comprehensive policies are needed to effectively mitigate the health impacts of this industry.

Petrochemical plants

The petrochemical industry is a major source of toxic air emissions, releasing chemicals such as ethylene oxide and chloroprene, which are known or suspected to cause cancer and other serious health problems. These emissions also contribute to climate change, as the chemicals released have a heating effect on the planet. A study in Texas found a correlation between proximity to oil refineries and higher rates of bladder, breast, colon, lung, lymphoma, and prostate cancers.

The impact of petrochemical pollution is exacerbated by the fact that these facilities are often located in African American, Latino, and low-income neighborhoods, which are frequently designated as mixed residential-industrial zones. This trend has worsened for Latino communities in the US over the past two decades. The result is that vulnerable communities are disproportionately exposed to toxic air pollution, with a higher risk of cancer and other health issues.

To address this issue, the US Environmental Protection Agency (EPA) has issued new regulations to reduce toxic emissions from petrochemical plants. The updated standards, known as the Hazardous Organic NESHAP or HON Rule, aim to reduce toxic air pollution, protect public health, and establish foundational protections for communities living near these facilities. The rules focus on limiting six of the EPA's high-priority chemicals of concern and are expected to reduce toxic air pollution by more than 6,000 tons each year.

In addition to government regulations, there are increasing incentives for sustainable manufacturing processes. Companies are motivated to proactively address air emissions to maintain operations and a positive reputation. Technologies such as scrubbers and oxidizers can be used to treat the byproducts of petrochemical processing and remove specific chemical waste generated by each process.

Hazardous waste

Industrial facilities are a significant contributor to air pollution, and this is often due to the hazardous waste they produce. Hazardous waste is a by-product of many industrial processes, and it can have a detrimental impact on the environment and human health if not properly managed and disposed of.

The natural gas, plastic, chemical, electric generation, and waste disposal industries are some of the major producers of hazardous waste. When new industrial facilities begin operating, they often require additional waste disposal operations, which can create more air and water pollution. Even the treatment facilities designed to manage hazardous waste can generate their own waste streams, which then require further disposal, creating a cycle of pollution.

In addition to the direct release of hazardous waste into the environment, the improper storage and disposal of such waste can also lead to air pollution. For example, waste incineration, a common method of disposal, can create significant amounts of smog-causing air pollution, as well as hazardous ash that must be landfilled. The Clean Air Council and similar organizations work to prevent the construction of hazardous waste incinerators and advocate for safer waste treatment and disposal practices.

Furthermore, industrial facilities often release toxic chemicals into the air, which can then contaminate the surrounding soil and groundwater. This can have direct health consequences for nearby residents, including developmental disorders in children. It is essential that facility managers and regulators are aware of effective waste management tactics and work towards implementing sustainable practices to minimize the impact of hazardous waste on the environment and human health.

Carbon emissions

Direct emissions from industrial processes, such as chemical reactions and the use of refrigerants or methane, also contribute significantly to carbon emissions. In addition, the construction industry is responsible for a substantial portion of global carbon emissions, with energy-intensive processes and the use of fossil fuels on building sites. Inefficient and outdated technology, as well as a lack of pollution controls, exacerbate the problem.

To reduce carbon emissions from industrial facilities, several strategies can be implemented. Firstly, improving energy efficiency in industrial processes and buildings is crucial. This includes optimizing production processes, using high-efficiency equipment, and implementing renewable energy sources such as electrification of thermal processes. Redesigning industrial processes to use less energy and transitioning to low- and no-carbon energy sources are also effective measures.

Additionally, addressing emissions in the manufacturing sector requires a combination of technological innovation, process optimization, and a shift towards cleaner energy sources. Carbon capture technology can also play a role in reducing emissions, although the cost and infrastructure requirements can be challenging. The federal government has provided incentives, such as the 45Q tax credit, to encourage the adoption of carbon capture technology in manufacturing.

Overall, reducing carbon emissions from industrial facilities requires a multifaceted approach, including improvements in energy efficiency, transitions to renewable energy sources, and the implementation of pollution control measures. By addressing these issues, we can mitigate the impact of industrial facilities on air pollution and work towards a more sustainable future.

Nitrogen oxides

Nitrogen dioxide is a significant component of NOx and is known to have detrimental effects on human health. It is formed when fossil fuels are burned at high temperatures, and it contributes to particle pollution and the formation of ozone in the atmosphere. People can be exposed to nitrogen dioxide by living near industrial facilities, power plants, or busy roads that emit this pollutant. Additionally, indoor exposure can occur through the use of appliances that burn natural gas, liquefied petroleum gas (including propane and butane), or kerosene, such as stoves, dryers, and space heaters.

The health impacts of nitrogen dioxide pollution are far-reaching. Short-term exposures to elevated levels of nitrogen dioxide can irritate the airways and aggravate respiratory diseases, particularly asthma. This can lead to coughing, wheezing, and difficulty breathing, resulting in hospital admissions and visits to emergency rooms. Prolonged exposure to high concentrations of nitrogen dioxide may also contribute to the development of asthma and increase susceptibility to respiratory infections. Scientific evidence suggests that exposure to nitrogen dioxide could be a factor in causing asthma in children.

To address the issue of nitrogen oxide pollution, various measures have been implemented. The federal Clean Air Act in the United States, for example, has helped drive down nitrogen dioxide emissions and improve air quality nationwide. Additionally, the Environmental Protection Agency (EPA) has established national and regional rules to reduce NOx emissions, aiding state and local governments in meeting air quality standards. However, despite these efforts, many people still breathe unhealthy levels of nitrogen dioxide, particularly those living near emission sources. It is crucial for individuals to take protective measures and advocate for further cleanup of air pollution to mitigate the harmful effects of nitrogen oxide pollutants on human health and the environment.
