What You'll Learn
Mushrooms are the fruit of a fungus, which feeds on dead organic matter
Mushroom farming is sustainable for several reasons. Firstly, mushrooms have a lower water footprint compared to many other crops, requiring only about 3.9 gallons (15 litres) of water to produce 2.2 pounds (1 kilogram) of mushrooms. Additionally, mushroom farms recycle by-products from other agricultural sectors, such as crushed corn cobs, cottonseed hulls, and soybean hulls, which helps manage waste from other agricultural operations. The substrate material used to grow mushrooms can also be recycled as a soil amendment.
Indoor mushroom farming also allows for better control of environmental factors, land use, and energy and water needs. Modern mushroom production is energy-efficient, utilising heat generated by composting to warm production facilities. While emissions can vary depending on the type of mushrooms, production methods, and energy sources used, farms that utilise solar power or other forms of green energy can significantly reduce their carbon footprint.
Mushrooms themselves have a unique nutrient profile, containing vitamins and minerals not commonly found in plant- or animal-derived foods. They are also used in various applications beyond food, including meat replacements, building materials, textiles, and biodegradable coffins.
Furthermore, mushrooms have been explored as a source of renewable energy. In one example, scientists combined mushrooms with 3D printing and cyanobacteria to produce electricity. The bacteria used in this process can turn sunlight into electric current, producing bio-electricity. This innovative use of mushrooms showcases their potential beyond just food and agricultural applications.

Mushroom farming is sustainable due to low water usage
Mushroom farming is an increasingly popular form of sustainable agriculture. Mushrooms are a nutritious food with a very small environmental footprint. They require fewer resources to grow than traditional crops, making them an environmentally friendly choice. One of the key advantages of mushroom farming is its low water usage.
Mushrooms are highly efficient at converting waste products into food. They can be cultivated in a controlled indoor environment using waste products like sawdust, straw, and agricultural byproducts. This means that mushroom growers are able to recycle waste from other sectors of agriculture, reducing the amount of water needed. According to the American Mushroom Institute, growers use smart management and production practices that use less than 2 gallons of water to produce one pound of button mushrooms. This is around 32 (8 oz) glasses of water to grow, harvest, and process an entire pound of mushrooms, compared with an average of 50 gallons of water per pound of other fresh produce items.
Mushroom farming also has a low energy footprint. Producing one pound of button mushrooms takes 1.0 kilowatt-hour (kwh) of electricity, the same amount of energy as it takes to run a coffeemaker for one hour each day. This efficiency means that growing one pound of mushrooms generates just 0.7 pounds of CO2 equivalents.
Mushrooms are also beneficial for improving soil health. Fungi play a crucial role in ecosystems as primary and secondary decomposers. As they digest and decompose organic matter, they create small particles they can absorb, making nutrients available for other organisms and improving the soil. This ability to convert low-quality and low-value waste materials into high-quality food makes mushrooms a valuable crop for farmers, whether in urban or rural settings.
The sustainability of mushroom farming is further enhanced by the fact that mushrooms can be grown in small spaces, making them ideal for urban farming. Additionally, because they are grown indoors, they require fewer pesticides and herbicides than traditional crops, reducing the environmental impact associated with agriculture.

Mushrooms can be used to produce electricity
Mushrooms are the fruiting bodies of fungi, which are neither plants nor animals. They cannot produce their own food like plants, and instead, they derive nutrients from their environment. Fungi play a crucial role in ecosystems as primary and secondary decomposers. They digest organic matter, creating small particles they can absorb, and simultaneously making nutrients available for other organisms and improving the soil.
Mushrooms have several environmentally-friendly applications, and one of them is producing electricity. Scientists have discovered a way to generate electricity from mushrooms, which could be a new form of sustainable energy. This discovery is exciting news for green technology.
A team of researchers, including Sudeep Joshi, a postdoctoral researcher at the Stevens Institute of Technology, found that mushrooms could be used to generate electricity from cyanobacteria. They had initially been experimenting with cyanobacteria by placing them on artificial surfaces, but the bacteria failed to thrive. However, Joshi realized that mushrooms naturally host several bacteria and could be used as a surface for the bacteria.
The researchers used 3D printing to deposit the cyanobacteria onto the mushrooms. The bacteria produce electricity by turning sunlight into an electric current through photosynthesis. This process splits water molecules, releasing electrons, which then flow into the graphene nano-ribbons printed onto the mushrooms.
While the amount of electricity generated by this method is currently very small, it shows promise for the future of eco-friendly electricity production.

Fungi are neither plants nor animals
Mushrooms are the fruiting bodies of fungi, which are often hidden underground or inside decaying organic matter. Fungi are neither plants nor animals, despite often being mistaken for vegetables. Fungi cannot produce their own food like plants do, and instead, they absorb nutrients from their environment.
Fungi have a complex classification and have been studied by both botanists and zoologists. For a long time, fungi were classified as plants, based on the observation that they are immobile and have rigid cell walls. However, it was later discovered that fungi lack chloroplasts, a key feature of plants.
Fungi are now understood to be more closely related to animals than plants. This is because they share a common ancestor with animals, which can be observed in the structure of their cells. All plants have cell walls made from cellulose, while all animals lack cell walls entirely. On the other hand, fungi have cell walls made of chitin, which is a substance not found in plants or animals.
Fungi have unique characteristics that set them apart from plants and animals. They play a crucial role in ecosystems as primary and secondary decomposers, breaking down organic matter and making nutrients available for other organisms. This process also improves soil quality.
The study of fungi has led to exciting innovations, such as using mushroom mycelium to create meat replacements, building materials, textiles, and biodegradable coffins. Additionally, mushrooms have been used in renewable energy research, where they serve as hosts for bacteria that produce bio-electricity.
