The pulp and paper industry and the oil industry are two of the most polluting sectors. Paper mills produce waste water that contains solids, nutrients, and dissolved organic matter, which can cause eutrophication in fresh water bodies. They also consume and pollute large amounts of water, and discharge solid waste that can occupy land and emit odors. Oil refineries, on the other hand, emit atmospheric pollutants, produce toxic waste, and consume large amounts of water and energy. They release volatile compounds and greenhouse gases, such as carbon dioxide, methane, nitrogen oxides, and sulphur dioxide, which contribute to climate change and air quality deterioration. Both industries have a significant impact on the environment, but in different ways. This article will explore and compare the environmental impacts of paper mills and oil refineries, to determine which industry has a worse effect on pollution.

Paper mills emit hydrogen sulfide, causing foul odour and health issues
Oil refineries and paper mills have both been criticized for causing environmental pollution. Oil refineries are responsible for transforming crude oil into useful products, and while they are vital for the modern domestic and global economy, they are not beneficial to the environment. Oil refineries cause air pollution through the emission of toxins, and water pollution through the release of treated wastewater containing trace amounts of toxins into local bodies of water. Additionally, the process of extracting and refining crude oil results in physical waste generation, such as sludge and residues.
Paper mills, on the other hand, have been associated with the emission of hydrogen sulfide, a colorless gas with a strong odor resembling rotten eggs. This gas is produced during the kraft pulping process, where it is formed alongside other sulfur compounds. Hydrogen sulfide is not only unpleasant due to its smell but also poses significant health risks. Exposure to this gas can lead to irritation of the eyes, nose, and throat, difficulty breathing for asthmatics, headaches, poor memory, tiredness, balance issues, and even death in concentrated doses.
The New-Indy paper mill in Catawba, South Carolina, has been at the center of a pollution crisis, attracting more than 30,000 complaints due to its foul smell. The mill's emissions of hydrogen sulfide have resulted in federal and state orders to reduce its emissions, with the EPA issuing an emergency order for the plant to address the issue. The mill's stack test in 2020 revealed small particle pollution levels that were significantly higher than those of other large U.S. paper mills, with rates of up to 300 pounds per hour.
The impact of paper mills on the environment and public health cannot be overlooked. The emission of hydrogen sulfide, a component of Total Reduced Sulfur (TRS) compounds, has led to unpleasant odors and a range of health issues for residents near paper mills. While oil refineries also contribute to pollution, the specific issue of hydrogen sulfide emissions from paper mills has triggered a significant number of complaints and concerns, highlighting the need for improved environmental and health protections in these industries.

Paper mills release particulate matter, which can cause cardiovascular issues
While both paper mills and oil refineries contribute to pollution, the former has been singled out for releasing particulate matter, which is among the most harmful pollutants. Particulate matter is made up of particles 50 times smaller than a grain of sand, and these particles can bond with other toxins, infiltrate the bloodstream, and damage the heart, lungs, and nervous system.
For instance, the New-Indy paper mill in South Carolina has been the subject of more than 30,000 complaints due to its release of hydrogen sulfide, a gas with a rotten egg smell that can cause headaches and even death in concentrated doses. The mill's 2020 stack test revealed small particle pollution that peaked at nearly 300 pounds an hour, which is up to 50 times higher than other large U.S. paper mills.
By comparison, Exxon Mobil Corp’s Baton Rouge oil refinery, the highest among U.S. refiners, averaged 138 pounds of particulate matter per hour during its latest available stack test. While oil refineries do cause air pollution and water pollution, the extent of the latter depends on technology and the environmental responsibility of the operator. Refineries treat their wastewater, but it can still contain trace amounts of toxins that are released into local bodies of water.
Particulate matter air pollution has been linked to a range of cardiovascular issues. Clinical studies have shown that particulate matter air pollution has more detrimental effects on human health than gaseous components. Both acute and chronic exposure to particulate matter air pollution is associated with an increased risk of death from cardiovascular diseases, including ischemic heart disease, heart failure, and ischemic/thrombotic stroke.
Additionally, particulate matter has been identified as an important endocrine disrupter, contributing to the development of metabolic diseases such as obesity and diabetes mellitus, which are themselves risk factors for cardiovascular disease. Exposure to fine particle pollution over a few hours to weeks can trigger cardiovascular disease-related mortality and non-fatal events, while exposure of a few years or more increases the risk of cardiovascular mortality and decreases life expectancy.

Oil refineries generate over 800 toxic chemicals, impacting ecosystems and climate
Oil refineries are industrial facilities that have a significant environmental impact due to the emission of atmospheric pollutants, the production of toxic waste, and the intensive consumption of water and energy. These complexes release harmful gases that affect air quality, leading to the degradation of ecosystems and climate change.
The oil industry is one of the most regulated sectors worldwide, and its atmospheric emissions are subject to strict legislation. However, refineries can generate over 800 toxic chemicals, many of which are harmful to human health and the environment. These toxic chemicals are released into the air, water, and soil, endangering the health of billions of people worldwide and contributing to inequities.
One of the most notorious toxic chemicals present in the air near refineries is benzene, which is highly carcinogenic. Studies have shown higher rates of leukaemia in workers exposed to high levels of benzene in the refining industry. Benzene also causes neurological, reproductive, developmental, and immunological damage. Other hazardous air pollutants emitted by refineries include toluene, xylene, hexane, hydrofluoric and sulfuric acids, heavy metals such as mercury, nickel and cadmium, and organic compounds such as formaldehyde and acetaldehyde.
In addition to air pollution, oil refineries also contribute to water pollution. In the United States, refineries treat their wastewater, but it can still contain trace amounts of toxins that are released into local bodies of water. Refinery operators and oil producers aim to monetise every constituent component of the crude oil they refine, but some portion of it is always left as physical waste, such as sludge and residues, which must be disposed of.
While paper mills have also been associated with high levels of pollution, the impact of oil refineries on the environment and human health is far-reaching and cannot be ignored. Oil refineries are a major source of toxic chemicals, contributing to air, water, and soil contamination, and endangering the health of people worldwide.

Oil refineries release harmful gases, including carbon monoxide and nitrogen oxides
Oil refineries are responsible for transforming crude oil into useful products. While they are vital for the modern domestic and global economy, as well as fulfilling the basic needs of consumers, they are not beneficial to the environment. In fact, refineries are among the most toxic industries, ranking 10th on a toxicity list of over 200 grades, according to data from the Environmental Protection Agency (EPA).
Oil refineries are one of the most significant contributors to air pollution, releasing harmful gases such as carbon monoxide, nitrogen oxides, sulphur dioxide, and volatile organic compounds. These gases contribute to global warming, smog, and acid rain, which negatively impact the environment and human health. Communities near refineries are particularly vulnerable, experiencing higher rates of asthma and other lung conditions. Prolonged exposure to these pollutants can cause respiratory and cardiovascular diseases and increase the risk of cancer.
Nitrogen oxides (NOx) and sulphur oxides (SOx) move to higher levels of the atmosphere, reacting with oxygen and water vapour to produce acid rain. This phenomenon harms crops, forests, and ecosystems by decreasing growth and damaging foliage. Additionally, NOx contributes to the formation of ground-level ozone, which, along with VOCs, traps heat in the atmosphere, exacerbating global warming.
Oil refineries also contribute to water pollution, releasing treated wastewater that may still contain trace amounts of toxins into local water bodies. Physical waste is also generated in the form of sludge and residues, which must be disposed of. While biodiesel, derived from recycling waste cooking oil, is a more environmentally friendly alternative, oil refineries continue to release harmful gases, including carbon monoxide and nitrogen oxides, causing significant air pollution.

Water pollution is caused by oil refineries, with toxins released into local water bodies
Oil refineries are indeed detrimental to the environment, and water pollution is one of the key issues they present. While the degree of pollution can vary depending on factors such as age and technology used, it is clear that refineries contribute to water pollution. This is due to the discharge of contaminated wastewater, which still contains trace amounts of toxins, into local water bodies. Even though wastewater is treated, it can still contain harmful substances. As a result, the water pollution caused by oil refineries can have significant ecological and environmental impacts.
The process of refining crude oil inevitably generates physical waste, including sludge and residues. These by-products are often disposed of in water bodies, leading to the contamination of aquatic ecosystems. The sludge and residues can contain harmful chemicals and pollutants that are toxic to aquatic life and can also accumulate in the food chain, eventually affecting human health.
Additionally, oil refineries may also contribute to water pollution through accidental spills and leaks. During the extraction, transportation, and refining processes, there is a risk of oil leaking into nearby water sources. Oil spills can have catastrophic consequences for aquatic life, as the oil can coat and suffocate plants and animals, as well as contaminate drinking water sources.
Moreover, the refining process itself requires significant water usage, which can further deplete and pollute local water resources. The water used in the refining process may become contaminated with chemicals and pollutants, and if not properly treated and disposed of, can find its way back into water bodies, exacerbating the pollution problem.
It is important to note that the impact of oil refineries on water pollution is not uniform and varies depending on the region and the regulatory framework in place. Developed countries with stricter environmental regulations and enforcement may have lower levels of water pollution from refineries compared to developing countries with weaker environmental protections.
In conclusion, oil refineries are a significant contributor to water pollution, and their operations can have far-reaching consequences for the environment and public health. While the degree of pollution may vary, it is clear that the discharge of contaminated wastewater and the generation of toxic waste are key factors in the pollution of local water bodies. To mitigate these impacts, stricter environmental regulations, improved waste management practices, and the adoption of cleaner alternative fuels are necessary to reduce the water pollution caused by oil refineries.
