Burning Matches: A Pollutant In Disguise?

Burning matches may cause pollution, but it is difficult to ascertain the extent of their environmental impact. Matches are made from renewable materials like wood and bamboo, and a single match only burns for a few seconds, so the amount of sulfur dioxide emitted is likely minimal. However, the production of matches has been linked to freshwater aquatic and terrestrial ecotoxicity, and the carbon footprint of a carton of matches can be significant. Additionally, matchsticks may contain non-biodegradable materials like paraffin wax and glass, contributing to deforestation and pollution through mining. While the direct impact of burning matches may be negligible, the cumulative effect of producing and disposing of them could have adverse environmental consequences.

Matchstick production and transport

Matchstick production relies on a consistent supply of raw materials, primarily wood and chemicals. The wood, usually softwood like pine or aspen, forms the body of the matchstick, while the match head is composed of chemicals like potassium chlorate, sulfur, and phosphorus. The striking surface, which creates the friction necessary to ignite the match head, is typically made from red phosphorus and glass powder.

The procurement of these raw materials can be challenging due to fluctuations in timber prices and availability caused by factors such as weather conditions, deforestation, and transportation costs. In addition, the chemicals required for the match head and striking surface are sourced from different suppliers with varying pricing structures and quality standards, further complicating the production process.

The matchstick production industry is subject to stringent environmental regulations due to the potential harm caused by the chemicals used. Manufacturers must ensure proper waste management practices, including the disposal of waste chemicals, emissions control, and the handling and storage of chemicals to prevent leaks and spills. Compliance with these regulations can be challenging, especially for smaller manufacturers, as it may require significant investments in specialized equipment and infrastructure.

Transportation is a critical aspect of the matchstick production and distribution process. While it facilitates the sale and distribution of matchsticks, it also contributes to environmental challenges. The transportation sector is a significant source of greenhouse gas emissions, air pollution, noise pollution, and habitat fragmentation. Initiatives to reduce the environmental impact of transportation include improving energy efficiency, transitioning to electric vehicles, and promoting sustainable mobility options such as public transport, walking, and cycling.

Overall, matchstick production and transport have economic and environmental implications. While the industry faces challenges in raw material procurement and environmental compliance, efforts to reduce pollution from transportation sources have yielded positive results, contributing to improved air quality and public health.

Sulfur dioxide and other toxic chemicals

Matches contain sulfur, which, when burned, produces sulfur dioxide. While a single match would emit a minimal amount of sulfur dioxide, the chemical is a toxic air pollutant that can cause eye and nose irritation, coughing, headaches, and difficulty breathing. Sulfur dioxide is particularly harmful to individuals with heart disease, asthma, emphysema, or other respiratory diseases.

Furthermore, the production of matchsticks involves the use of materials such as paraffin wax, which is linked to deforestation and pollution due to mining. The water footprint for creating a single carton of matchsticks is about 265 liters (70 gallons), and the energy required for production comes primarily from fossil fuels. As a result, matchstick manufacturing contributes to freshwater aquatic and terrestrial ecotoxicity.

The burning of matches also produces other toxic chemicals, such as nitrogen oxides, volatile organic compounds (VOCs), and polycyclic organic matter (POMs). These chemicals can have adverse effects on both human health and the environment. For example, POMs, which are released during the burning of plastic and treated wood, have been linked to lung and neurological diseases and an increased risk of certain cancers.

Additionally, the smoke and ash from burned matches can contaminate the soil, groundwater, lakes, rivers, and streams. This contamination can enter the human food chain through crops and livestock, potentially causing long-term health issues. While the direct impact of burning a single match may seem insignificant, the cumulative effect of burning matches on a large scale can contribute to air pollution and have detrimental consequences for human health and the environment.

Single-use nature of matches

Matches are often overlooked when it comes to their environmental impact due to their small size and disposability. However, their single-use nature contributes to waste generation and resource depletion. While a matchstick might burn for only a few seconds, the resources and energy consumed in its production cannot be ignored.

The production of matchsticks involves various materials and processes that have ecological repercussions. For instance, the water footprint for manufacturing a single carton of matchsticks is approximately 265 litres (70 gallons). This significant water usage could exert pressure on water resources, especially in water-stressed regions. Moreover, the energy required to create a carton of matchsticks is about 715,860 megajoules, predominantly derived from fossil fuels. This energy consumption contributes to carbon emissions and climate change.

The single-use nature of matches also extends beyond the matchsticks themselves. Matchstick production relies on materials like paraffin wax, which is linked to deforestation and pollution due to mining. The mining of non-renewable resources, such as those used in lighters (metal, plastic, or glass), can lead to soil erosion, deforestation, and the release of emissions. While matches may be made from renewable materials, the single-use nature of these products means that resources are consumed faster than they can be replenished.

Additionally, the waste generated from matchsticks is not easily recyclable. The leftover matchsticks, along with any packaging, contribute to landfill waste. While wooden matchsticks are biodegradable, coatings or additives might hinder this process or introduce harmful chemicals into the environment as they decompose. The non-biodegradable waste from matches, if burned, could release toxic chemicals, further exacerbating air pollution.

The single-use nature of matches underscores the importance of considering alternatives. Reusable lighters or ignition sources, for example, could reduce the environmental impact associated with the production and disposal of matchsticks. While matches might seem insignificant due to their small size and brief usage, their cumulative impact on the environment is noteworthy, especially given their widespread use.

Renewable materials used in matchsticks

Matches are made from a variety of materials, some of which are renewable, while others are linked to deforestation and pollution. The matchstick, or handle, is traditionally made from wood, specifically poplar, pine, or aspen, for their light colour and ability to splinter easily. This allows them to be cut into thin sticks. Today, the type of wood is less important than its processing, as most matchsticks are soaked in flame-retardant materials, such as ammonium phosphate, to prevent them from catching fire when struck.

The match head, or tinder, contains the ignition material. The specific composition depends on the type of match, but generally, it involves a reaction between potassium chlorate and phosphorus. Some matches, known as "strike anywhere" matches, have all their active ingredients in the head, making them less safe than "safety matches", which separate the ingredients. The head may be made from potassium chlorate, a form of phosphorus (e.g. phosphorus sulfide), and a binder.

While matches are made from renewable materials like wood, and to a lesser extent, bamboo, other materials used in their production are less sustainable. Paraffin wax, for example, is used to coat wooden matchsticks, and is linked to deforestation and pollution due to mining. The production of matches also has a significant carbon and water footprint, with a high energy requirement, mostly from fossil fuels. The water footprint for a single carton of matchsticks is about 265 litres (70 gallons), and the energy requirement is 715,860 megajoules of energy, which is a cause for concern.

Overall, while matches do use some renewable materials, their production and use contribute to environmental concerns, particularly regarding deforestation, pollution, and carbon emissions.

Health effects of smoke exposure

Smoke exposure carries a range of health risks, from minor to severe. Even short-term exposure to smoke can cause eye, nose, and throat irritation, difficulty breathing, coughing, and headaches. The odour of smoke can also be nauseating.

Some people exposed to heavy smoke experience temporary changes in lung function, making breathing more difficult. Smoke can also cause changes in heart function, with carbon monoxide reducing the body's oxygen supply and aggravating heart conditions such as angina. Fine particles from smoke can travel deep into the respiratory tract, reaching the lungs, and causing respiratory irritation and shortness of breath. These fine particles can also worsen existing medical conditions like asthma and heart disease. Physical exertion can exacerbate these health effects.

Frequent exposure to smoke, even for brief periods, can increase the risk of long-term health issues. Studies of firefighters, for example, have shown a higher rate of cancer, lung disease, and cardiovascular disease. Exposure to smoke can also increase the risk of premature death.

The type of pollutants emitted by smoke depends on the materials being burned. Smoke from burning vegetation and organic materials contains toxic gases such as carbon monoxide, carbon dioxide, nitrogen oxides, and hydrocarbons. Burning trash, plastics, and treated wood releases heavy metals and toxic chemicals such as dioxin, benzo(a)pyrene, and polyaromatic hydrocarbons, which have been linked to cancer.
