Pollution's Benefits: Can We Turn Bad To Good?

While pollution is a pressing global issue with severe consequences for human health and the environment, some argue that it may have certain benefits. For instance, a study published in Nature found that hazy weather caused by pollution has increased plants' ability to process carbon dioxide, leading to a 10% increase in carbon fixation in the soil compared to the 1960s when air quality was better. Additionally, pollutants like nitrogen and sulfur, released by power plants, reflect sunlight back into space, contributing to a cooling effect that helps mitigate global warming. However, it is essential to recognize that the overall impact of pollution is detrimental, and the potential benefits do not outweigh the urgent need to address this global crisis.

Pollution can be turned into art

Art has long been a medium for social commentary, so it is no surprise that artists are now using pollution as a medium to highlight one of the most pressing issues of our time.

Michael Pinsky's Pollution Pods consist of five domes, each filled with air imitating the air quality of five different areas of the world: Northern Norway, London, New Delhi, Beijing, and São Paulo. As you move through the domes, you experience varied levels and sources of air pollution. Pinsky recreates the smell of diesel for London, mixes the smells of industrial fumes, coal or wood-based heating, and transportation emissions for Beijing, and includes small whiffs of burnt plastic and grass in the New Delhi dome, as citizens there still burn a lot of their rubbish.

Pinsky's work only copies the smell and visibility of the harmful air, without including the actual harmful gases, but the experience is still far from pleasant. This is intentional, as Pinsky wants people to understand that air pollution is not a pleasant experience for anyone. He hopes his work will lead to a more "radical approach" to dealing with air pollution, particularly in the transportation sector.

Another artist, Daan Roosegaarde, created the Smog-free Tower, which he calls the "largest smog vacuum cleaner in the world". The tower sucks up polluted air, cleans it using positive ionization technology, and releases it back into the atmosphere. Roosegaarde was motivated to create the tower after living in Beijing and witnessing the city's strive for economic development and citizen well-being. He wanted to contribute to the well-being of the environment and decided to use his engineering background to create a clean-air park or oasis. The towers are now found in China, Poland, the Netherlands, and soon, South Korea and Mexico.

Anirudh Sharma, while visiting his family in Mumbai, India, noticed that his white shirts would gradually turn speckled with something that resembled dirt. He realized that this was air pollution, specifically sooty particulate matter, made up of black particles released from vehicle exhausts. After returning to the Massachusetts Institute of Technology (MIT), Sharma set up Graviky Labs, a startup that has developed a technology to attach to diesel exhaust systems to capture particulate matter. The team at Graviky then treats the soot to turn it into ink, called Air-Ink, for use by artists around the world. So far, the startup has captured 1.6 billion micrograms of particulate matter, equivalent to collecting 1.6 trillion liters of outdoor air.

Through their art, Pinsky, Roosegaarde, and Sharma are raising awareness about air pollution, finding solutions to reduce it, and using it as a resource. They are helping to shine a light on the grave issue of air pollution and are inspiring others to take action to address it.

Smog can be turned into diamonds

While pollution is detrimental to human health and the environment, it can sometimes be turned into something useful. One such example is the process of converting smog into diamonds.

Dutch artist and designer Daan Roosegaarde's "Smog Free Project" is a creative initiative aimed at tackling air pollution in Beijing, China. The project consists of a 7-metre-tall tower, aptly named the "Smog Free Tower", that uses a positive ionization process to capture and filter tiny particles of pollution from the air. This innovative tower can clean up to 30,000 cubic meters of polluted air per hour and releases clean air back into parks and playgrounds, making the surrounding areas significantly cleaner than the rest of the city.

But what happens to the captured smog particles? This is where the remarkable transformation occurs. Daan Roosegaarde and his team discovered that over 30% of the collected pollution particles were carbon. Through a process of applying high pressure for approximately 30 minutes, this carbon can be converted into diamonds. These diamonds, often dark and boxy in shape, are then crafted into unique jewellery pieces such as rings and cufflinks. Each piece of jewellery represents the purification of 1,000 cubic meters of pollution, symbolising the transformation of a health hazard into a precious gem.

The proceeds from the sale of these smog diamonds are intended to support the development and installation of more Smog Free Towers. By turning smog into diamonds, Daan Roosegaarde's project not only addresses the pressing issue of air pollution but also creates a sustainable funding mechanism to expand the initiative. This waste-to-wonder conversion showcases the potential for innovative solutions to environmental challenges, demonstrating that even the most unpleasant aspects of pollution can be turned into something valuable and aesthetically pleasing.

While the Smog Free Project has specifically addressed air pollution in Beijing, it highlights the potential for similar initiatives in other polluted cities around the world. Daan Roosegaarde's work serves as an inspiration for creative thinking and the exploration of new technologies to combat pollution and create a brighter future for our planet.

Oil spills can be converted into advantages

Oil spills can have devastating effects on the environment, wildlife, and the economy. However, some believe that even oil spills can be converted into advantages. Here are some ways in which the negative impact of oil spills could potentially be mitigated and turned into opportunities:

Artificial Reefs

Old offshore oil rigs that are no longer in use are sometimes tipped over and left on the seafloor as part of Rigs-to-Reefs programs. Within a year, these structures become covered in barnacles, coral, sponges, clams, and other sea creatures. These artificial reefs can attract fish and increase fish populations, benefiting recreational fishing and diving opportunities.

Cooperation Between Industries

Cooperation between power plants and mariculture producers has resulted in successful fish-growing ventures in artificially heated waters. For example, oysters in Northport, lobsters in Maine, shrimp in Miami, and catfish in Nashville, Lake Colorado, Texas, and Washington, D.C., have all been successfully cultivated with the help of heated waters from power plants.

Restoration Projects

After an oil spill, restoration projects are implemented to actively bolster the environment. These projects can include building marshland, protecting bird nesting habitats, and constructing parks, boat ramps, and fishing piers. These efforts help speed up the recovery of different species and habitats affected by the oil spill.

Scientific Advancements

Oil spills, particularly large-scale incidents, have spurred advancements in scientific knowledge and technologies used to respond to and mitigate the impacts of such disasters. For example, the Deepwater Horizon oil spill in 2010 led to the development of new tools and models to estimate the movement and weathering of spilled oil.

While it is essential to recognize that the advantages mentioned above do not outweigh the detrimental effects of oil spills, exploring these potential silver linings can help inform strategies to mitigate the negative consequences and, in some cases, turn challenges into opportunities.

Pollution can be used to regulate climate change

While pollution is often viewed as detrimental to human health and the environment, there are certain contexts in which it can have positive effects or be utilised for beneficial purposes. One of the most pressing global challenges today is climate change, and there are ways in which pollution can be used to regulate it.

Firstly, certain pollutants in the atmosphere can actually help to keep global warming in check. Power plants that burn fossil fuels release a range of chemicals, including nitrogen and sulfur, which reflect sunlight back into space. These pollutants, known as aerosols, have a net cooling effect on the planet. While reducing these aerosols is beneficial for human health, it could potentially lead to increased global warming. This is a complex issue, as these same aerosols can also contribute to poor air quality and have negative impacts on human health, such as heart and lung disease.

Additionally, pollution can be captured and transformed into useful products. For example, Dutch artist Dan Roosegaarde's Smog Free Project involves using towers to suck up polluted air, clean it, and then release the clean air back into parks and playgrounds. The leftover carbon from the process is then turned into diamonds. Another example is the work of Newlight Technologies, which has created AirCarbon, a material that is 40% air and 60% greenhouse gas. AirCarbon is biodegradable, as strong as plastic, and can be moulded into various shapes, providing a greener alternative to traditional plastic.

Furthermore, there are instances where pollution has been utilised for beneficial purposes in the past. For instance, cooperation between power plants and mariculture producers has resulted in successful fish farming in artificially heated waters. Additionally, the toxic effects of quicklime on sea urchins helped restore giant kelp beds off the coast of San Diego, California. While these examples do not directly address climate change, they demonstrate how pollution can sometimes be harnessed for positive outcomes.

It is important to note that the positive aspects of pollution do not outweigh the significant negative consequences it has on the planet and human health. However, these examples highlight the potential for innovative solutions that can help mitigate the effects of pollution and, in some cases, utilise it for beneficial purposes.

Pollution can be used to create better packaging

While pollution is generally harmful to the environment, it can be used to create better packaging. The packaging industry is the largest and fastest-growing consumer of synthetic plastics derived from fossil fuels, with food packaging plastics accounting for the bulk of plastic waste. This has led to an urgent need for eco-friendly, sustainable packaging materials.

Biopolymers have emerged as a promising alternative, although they still have a very low market uptake. Polylactic acid (PLA) is the most favoured bioplastic due to its biodegradability, excellent transparency, and good barrier properties against oxygen and water vapour. PLA can be derived from the fermentation of carbohydrates such as starch or by chemical synthesis. It is also possible to blend PLA with other materials, such as natural fibres and fillers, to improve its mechanical and barrier properties.

Using biodegradable materials for packaging can result in reduced plastic waste, lower greenhouse gas emissions, and the sustainable exploitation of environmental resources. For example, recycling one pound of polyethylene, the most commonly used material in plastic water bottles, conserves up to 12,000 BTUs of heat energy.
