The structure trade is in search of options to concrete, the world’s most generally used constructing materials. Low-cost, versatile and robust, concrete is likely one of the most revolutionary substances in historical past. It might not be an exaggeration to say that cities as we all know them at the moment wouldn’t have been potential with out strengthened concrete. Nevertheless, the carbon footprint of cement manufacturing is big, accounting for 8% of world emissions every year. For comparability, it is a far greater share than the aviation trade, which is answerable for 2% of emissions. It isn’t onerous to see why architects are desirous about shifting away from concrete — and shortly.
Among the many options to concrete being researched, a fabric derived from fungus referred to as mycelium is by far essentially the most romantic. In 2024, everybody is aware of somebody obsessive about mushrooms and their alleged dietary, medicinal and psychotropic virtues. For these varieties, it simply is sensible, in an inventive or religious method, that fungi will rescue us from the local weather disaster we’ve created.
I imply this with no condescension in anyway: fungi are fascinating and galvanizing. They’ve additionally been round far longer than animals and vegetation. Personally, I like the concept of a future world the place we dwell in properties made from mycelium. There’s an simple Richard Scarry-esque allure to the picture of dwelling inside a mushroom.

So what precisely is mycelium? Briefly, mycelium is the root-like construction of a fungus. It capabilities each as a root system as we’d consider it — that’s, a fungus transports vitamins by its mycelium — but additionally as a sort of large mind. The mycelium of a fungal system sends electrical alerts to totally different components of the organism to warn of modifications within the surroundings.
In some instances, a mycelium system can span 1000’s of acres, as is the case in Oregon’s Malheur Nationwide Forest. Particular person mushrooms are merely the “fruiting our bodies” of this huge organism, which is estimated to be not less than 2,400 years previous.
Mycelium is extensively used on the earth of packaging, with corporations like Ikea and Dell utilizing it as an alternative of polystyrene, which isn’t biodegradable. The method for creating mycelium packaging is similar as for creating mycelium bricks, that are used for constructing.
First, natural waste is cleaned after which mixed with mycelium, which grows across the waste and digests the fabric. (Bear in mind: fungi eat their vitamins like we do. They’re really extra intently associated to animals than vegetation biologically). Then, the remaining materials is positioned right into a mould. It continues to develop to suit the form of the mould, and when it’s dried, voila! A mycelium brick is born. This course of is fast, taking solely 5 days.

Licensed Vitality, an environmental consulting agency in Australia, aptly describes the virtues of mycelium development: “Via bio fabrication a carbon impartial constructing course of could be achieved eliminating such merchandise as synthetic insulation utilized in partitions, MDF and different non load bearing buildings.” As well as, “Mycelium merchandise may present different advantages similar to termite proofing, with merchandise being created which are a magnet for termites however when eaten trigger a fungus spore to activate inside the termite killing it and making a fungus whose spores repel different termites.”
Stunningly, Licensed Vitality explains that “relative to its weight a mycelium brick is stronger than concrete with a cubic meter of mycelium brick weighing 43 kilograms and a cubic meter of concrete weighing 2400 kilograms” (95 kilos versus 5,290 kilos). Sadly, this isn’t essentially the most related metric. By quantity, quite than weight, mycelium has nowhere close to the compressive power of concrete, clocking in at 30 kilos per sq. inch versus 4000 kilos per sq. inch for concrete. These bricks is not going to be used to construct a house close to you within the close to future.
Hy-Fi by The Residing, New York Metropolis, New York
And but, there’s nonetheless one thing inspiring about mycelium’s capacities. In 2014, The Residing New York exhibited a tower referred to as Hy-Fi in entrance of MoMA PS1. Standing 43 ft (13 meters) tall, the construction was made from 10,000 compostable mycelium bricks. As mycelium bricks are created by the method of natural decomposition, the manufacture of the bricks for this tower resulted in fertile soil as an output, which is clearly vastly preferable to the carbon launched in cement manufacturing. Certainly, The Residing New York donated this soil to area people gardens.
One other unbelievable function of mycelium bricks: they’re technically nonetheless alive when they’re used. This permits them to bond to one another with out mortar and even heal themselves when cracks seem. Are you able to think about? A crack in your wall therapeutic by itself.
Mycelium is actually cool, and reveals promise as a fabric for insulation, furnishings, and the development of short-term buildings. Nevertheless, it’s sadly not a sensible various to concrete and even wooden. Researchers ought to contemplate the best way mycelium parts can complement sustainable structure quite than pitching it as a constructing materials by itself.
