Mycelium. It’s more than a concept kids learn about in school. It’s more than a way to restore ecosystems and help trees survive and thrive. It’s a material that may alter the way we build our homes, neighborhoods, and cities.
Mycelium is the vegetative part of a fungus, and researchers have been discovering its many uses for years. One includes creating innovative, sustainable building materials to revolutionize the construction industry.
In simple words: Living in mushroom homes never seemed more feasible.
Join us to explore the fascinating world of fungal architecture. We discuss how it works and how we may create eco-friendly buildings with unique properties.
Hint: we will discuss self-healing and fire resistance.
Where plants have roots, fungi have mycelium. This network of tiny, thread-like fibers grows underground, absorbing water and nutrients. Sometimes, the fruiting body (what we know as mushrooms) emerges above ground.
This material is self-healing. It consists of a network of fibers that easily break and re-form. Hyphae keep growing after receiving damage, essentially repairing themselves.
Mycelium has impressive fire resistance. It consists of fibers with low thermal conductivity, meaning it doesn’t spread heat. Its water contents make it less susceptible to ignition. It can also release water vapor and extinguish flames if heated.
Fungal architecture is also well-insulated. Mycelium is dense and three-dimensional, with air pockets that trap heat and keep living spaces comfortable.
The possibilities are endless, but scientists have a few general ideas.
One option is to use mycelium as a binding agent due to its adhesive properties. Combining it with sawdust or agricultural waste creates hardy, sustainable composite material.
Another option is to grow mycelium into blocks by placing it into a mold filled with nutrient-rich substrate. The resulting structures are light and sturdy, with minimal waste or carbon emissions.
Fungal architecture isn’t solely a theoretical concept: we can find real-world examples across the globe. Notable projects include:
As we’ve seen, mycelium has a range of impressive properties. But how does it compare to traditional options?
Concrete and wood have long been the go-to choices in the construction industry. Their durability compares to mycelium, but they lack self-healing ability. Fungal materials are lightweight and easy to transport, making them easier to use on-site. They’re also simple to cut and shape without specialized tools, saving time and money during construction.
Buildings are complicit in the climate crisis. Their creation and existence contribute 39% of the world’s carbon footprint. Of this staggering percentage, 11% is from construction and materials. Mycelium is much environmentally friendlier.
Fungal materials are grown rather than manufactured, meaning they have a smaller carbon footprint. They may even sequester (isolate and diminish) carbon dioxide as they develop.
Fungal blocks also produce less waste. Concrete, wood, and bricks scraps and debris often end up in landfills. We can compost fungal leftovers and use them as nutrient-rich soil additives.
Fungal architecture may require a higher initial investment but offers significant long-term savings. Being durable against wear and tear, they require less maintenance and replacements.
The production process is also less resource-intensive. We can grow mycelium with organic waste, reducing the use of energy and raw materials.
Sustainable building materials of fungi are promising, but they come with unique challenges.
Notably, scalability and availability can be problematic. While fungi rapidly grow, producing large quantities for commercial construction is still hard. They also require specific nutrients, some of which are expensive or inaccessible.
Scientists and engineers are developing methods for producing mycelium blocks efficiently and cost-effectively. For instance, these materials may grow in farm manure or combine with existing materials for added sturdiness. The projects are in their infancy, but promising.
Fungal architecture can be game-changing for eco-friendly construction. Startups are coming up to make it commercially available for components like:
The future of sustainable building materials relies on continued interest and investment. As science meets industry, we can expect greater demand and innovation.
Mycelium as a sustainable building material has massive potential. It offers various environmental benefits, potential cost savings, and safety for people within homes.
While issues remain, ongoing research is looking bright. Experimental architecture already proved it possible: all that’s left is expansion. Since the world is going greener, we may see those mushroom homes spring into reality.
Let’s continue to push the boundaries with fungal architecture and work towards a more sustainable future. Visit our blog for more fascinating explorations in this field.
