Mushrooms: Nature's Air Purifiers?

Mushrooms have been proposed as a solution to air pollution, with some claiming that they can clean the air. Mycelium, the root structure of mushrooms, has been found to capture carbon dioxide and absorb harmful hydrocarbons as it grows. This has been utilised in projects such as The Growing Pavilion, a building in the Netherlands made from mushrooms, which cleans the air as it grows. Additionally, mushrooms have been used to filter oil from canals and break down petroleum and other pollutants. However, it is important to note that indoor mushroom cultivation can create unhealthy air quality issues, and long-term exposure to mushroom spores can lead to lung inflammation and respiratory issues. Overall, while mushrooms have shown promise in cleaning the air and combating pollution, further research and careful consideration of potential risks are necessary.

Mycelium, the root structure of mushrooms, captures CO2 as it grows

Mycelium, the root structure of mushrooms, is a natural, workable material with several beneficial properties. One of its most notable characteristics is its ability to capture carbon dioxide (CO2) as it grows. This makes mycelium a potential solution for improving air quality and combating climate change.

Mycelium has been found to absorb a significant amount of CO2 from the air. During its growth, mycelium can capture twice its weight in carbon dioxide. This property has led to the development of innovative applications such as The Growing Pavilion, a bio-based building in the Netherlands constructed using materials like mycelium and timber. Mycelium was grown in molds using a hemp waste substrate, resulting in a strong, lightweight, and fire-retardant product.

Beyond building construction, mycelium's capacity to capture CO2 has broader implications for addressing air pollution and reducing greenhouse gas emissions. For example, mycelium-based products like Myco-Hex tiles can be integrated into building facades or used as modular hexagonal tiles, absorbing up to 80% of the carbon dioxide in the surrounding air. Additionally, mycelium plays a crucial role in breaking down complex carbon chain molecules, such as those found in leaves and wood, through the production of specific enzymes.

The ability of mycelium to capture and break down carbon-based molecules has far-reaching potential. It offers a natural and innovative approach to tackling environmental challenges. By utilizing mycelium in construction, pollution cleanup, and ecosystem restoration, we can harness its CO2-capturing capabilities to create more sustainable and resilient environments. Furthermore, mycelium's rapid growth and unique properties, such as its ability to absorb hydrocarbons, make it a promising tool for addressing air pollution and mitigating the impacts of climate change.

Overall, the root structure of mushrooms, known as mycelium, plays a vital role in capturing CO2 during its growth. This characteristic, coupled with its additional beneficial properties, positions mycelium as a promising natural solution for improving air quality, reducing pollution, and promoting sustainability in various applications.

Myco-Hex tiles, made from mycelium, absorb carbon dioxide and trap hydrocarbons

Mushrooms and their root structure, mycelium, have been found to have air-purifying properties. Mycelium is a natural, workable material that captures carbon dioxide as it grows. In fact, it can capture twice its weight in carbon dioxide. Mycelium is also capable of trapping hydrocarbons, which are harmful particles that can cause ailments such as psoriasis, eczema, and even skin cancer.

The use of mycelium in sustainable architecture, or "mycotecture", is an innovative solution to air pollution. Myco-Hex tiles are modular, hexagonal tiles made primarily of mushroom mycelium, a substance with explosive growth capacity. Myco-Hex tiles can absorb up to 80% of the carbon dioxide in the air and trap a large number of suspended hydrocarbon particles. This technology has already been proven effective in the cleanup of oil spills in the Niger Delta.

In addition to their air-purifying properties, Myco-Hex tiles offer other benefits. The tiles are strong, light, shock-absorbing, fire retardant, and provide insulation. They are also likely to have self-repairing properties. The production of these tiles is a natural process that uses minimal energy and resources. Mycelium grows on a substrate, using it for energy and nutrients. The substrate for Myco-Hex tiles can be wood sawdust, coffee grounds, or compost from organic waste.

The use of mycelium-based products has the potential to reduce the environmental impact of the construction industry. Concrete, the most widely used man-made material, is responsible for producing eight percent of the world's CO2 emissions. Mycelium-based structures, on the other hand, can help reduce carbon emissions and combat air pollution, creating more sustainable cities.

However, it is important to note that the indoor cultivation of mushrooms can create unhealthy air quality issues. Mushroom growers can develop breathing disorders due to the inhalation of polluted air and long-term exposure to mushroom spores. Therefore, the use of HEPA filters is recommended to ensure clean, unpolluted air during the mushroom cultivation process.

Oyster mushrooms are used to clean up oil spills and reduce toxins

Mushrooms have been used to clean up oil spills and reduce toxins. Oyster mushrooms, in particular, have been deployed for this purpose by enthusiasts and citizen scientists. Oyster mushrooms have mycelia that can clean contaminated water. They have been used to clean up oil spills in the Amazon, boat fuel pollution in Denmark, and contaminated soil in New Zealand.

Mycoremediation is a bioremediation technique that uses mushrooms to clean up hazardous waste. It harnesses their natural ability to use enzymes to break down foreign substances. Mycelium, the underground part of the fungus, breaks down heavier hydrocarbons into lighter-weight compounds that are less harmful to people and the environment. Oyster mushroom mycelia break down hydrocarbons more effectively when mixed with wood chips and compost.

In one test, researchers inoculated diesel-contaminated soil with oyster mushrooms and found that they reduced the concentration of toxic hydrocarbons from 10,000 parts per million to just 200 parts per million over 16 weeks. Oyster mushrooms have also been used to clean up the largest land-based oil spill in history, in the Ecuadorian Amazon.

In addition to cleaning up oil spills, mushrooms can also convert pesticides and herbicides into less harmful compounds, remove heavy metals from water and soil, and break down plastic. They can even remove arsenic, asbestos, copper, hexavalent chromium, lead, and zinc from the soil—all of which are pollutants that can result from wildfires.

The use of mushrooms to clean up toxic messes is an innovative and natural solution that has the potential to be cheaper than other methods. However, it is still being researched and may not be widely known or used.

Fungi can be used to clean up polluted air in cities

Fungi, including mushrooms, have been found to have air-purifying qualities, which could be used to clean up polluted air in cities. Mushrooms are already being used to clean up pollution around the world, from oil spills in the Niger Delta to post-wildfire cleanup in the wake of the 2017 Northern California wildfires.

The root structure of mushrooms, mycelium, is a natural, workable material that captures CO2 as it grows. Mycelium can absorb up to 80% of the carbon dioxide in the air and traps a large number of suspended hydrocarbon particles. Mycelium-based structures also have fireproofing and insulating properties.

The Growing Pavilion, a building in the Netherlands, was built using mycelium and other natural materials. Mycelium was grown on a hemp waste substrate, and the resulting product was strong, light, shock-absorbing, fire retardant, and provided insulation.

In addition to mycelium, solutions to air pollution using mushrooms often include compartments in which nutrients are stored, such as wood sawdust, coffee grounds, or compost from organic waste.

However, it is important to note that the indoor cultivation of mushrooms can create unhealthy air quality issues. Mushroom growers can develop breathing disorders due to the ongoing inhalation of polluted air in cultivation houses, and long-term exposure to mushroom spores can lead to lung inflammation.

Mushroom growers risk developing breathing disorders without the use of HEPA filters

Mushroom cultivation has become a booming industry, with many businesses and individuals setting up enclosed operations to regulate temperature, light, and humidity for healthier and more robust growing results. However, this popularity has come with a cost: indoor growing can create unhealthy air quality issues.

Mushrooms are highly susceptible to contamination, especially in the early stages of growth. The air in a mushroom-growing space can carry harmful spores and bacteria that can invade the substrate (the material mushrooms grow on). These spores are densely dispersed in the air, and growers can inhale large amounts while harvesting mushrooms. Long-term exposure to mushroom spores can lead to lung inflammation and even chronic respiratory diseases. Mushroom Worker's Lung, for example, is a common inflammatory condition associated with mushroom spore exposure. It is an immune system disorder where the lungs become inflamed as an allergic reaction to inhaled microorganisms, plant and animal proteins, or chemicals.

To prevent the inhalation of these spores and the development of breathing disorders, mushroom growers must use High-Efficiency Particulate Air (HEPA) filters. HEPA filters are an indispensable tool in mushroom cultivation, creating a clean, sterile environment that allows mushrooms to grow without the risk of contamination. They work by forcing air through a fine mesh that captures harmful particles like dust, pollen, mold, bacteria, and spores. By investing in a reliable HEPA filtration system, growers can ensure that their mushrooms have the best environment to thrive and avoid potential health risks.

Without the use of HEPA filters, mushroom growers are at risk of developing breathing disorders due to ongoing inhalation of polluted air. Therefore, it is crucial for the safety and well-being of mushroom growers to prioritize the use of HEPA filters in their cultivation operations.
