It’s October and the Citizen Science NC Mushroom Quest is on! We told you about the Mushroom Quest recently in this blog post, and your opportunity to do the Mushroom Quest through our fun scavenger hunt on Goosechase. We hope you’ll take advantage of that this month.
As I was reading through some interesting new science articles, as I do with my coffee every morning, I came across a fascinating new concept developed at the University of British Columbia (UBS) in Canada. What if the solution to cleaner, greener public restrooms was hiding beneath our feet in the roots of mushrooms? Researchers at the University of British Columbia (UBC) think so, and they’ve just unveiled the world’s first mushroom-powered toilet, a waterless system that turns waste into compost and fertilizer while eliminating the odors that often plague traditional composting toilets.
The experimental “MycoToilet” (seen here) uses mycelium—the underground fungal network that supports mushrooms—to help break down solid waste. In the process, the fungi and microbes neutralize more than 90% of the smelly compounds. Liquids and solids are separated, and over the course of a year, one unit could produce roughly 159 gallons of rich soil and more than 500 gallons of usable liquid fertilizer. Importantly, the system requires no extra water, electricity, or chemical additives.
The design team also considered user comfort and aesthetics. The MycoToilet is housed in rot-resistant cedar, includes a green roof, circulates air with a low-power fan, and is wheelchair accessible. Unlike older composting toilets, it was designed to avoid the stigma of being messy, smelly, or inconvenient.
So why does this matter here in North Carolina? Our state parks often face the challenge of balancing increased visitor use with sustainable infrastructure. Traditional flush toilets require plumbing and sewage treatment, which can be costly and difficult to install in remote natural areas. On the other hand, chemical toilets and older composting models can be unpleasant and environmentally unfriendly.
The MycoToilet points to a different path – sustainable sanitation that works with nature instead of against it. Imagine hiking in the Blue Ridge Mountains or kayaking along one of our many river systems and finding restrooms that are not only odor-free, but that also turn waste into something useful for the surrounding landscape. For parks and natural spaces that strive to model sustainability, mushroom-powered toilets could be a perfect fit.
While the technology is still in its pilot phase, the potential is huge. As North Carolina continues to invest in its state parks and myriad outdoor recreation opportunities, embracing innovations like the MycoToilet could make our public lands even more welcoming – and more sustainable – for generations to come.
