The University of British Columbia has developed the world’s first toilet based on mushroom mycelium. The device, called MycoToilet, does not require water, electricity, or chemical reagents, using natural processes to process waste.
The system separates waste into liquid and solid fractions. The solid fraction goes into a chamber with mycelium, where it is turned into compost. Thanks to enzymes and microbiota that form inside, the fungi neutralize more than 90% of unpleasant odors. The liquid waste is processed separately, forming fertilizer.
The toilet’s design includes antimicrobial and moisture-resistant cedar cladding, a green roof, and energy-efficient ventilation. It is fully accessible to users with limited mobility and requires minimal maintenance — about four times a year. This is especially relevant for parks, natural areas, and places with limited access to infrastructure.
According to estimates, the system can produce up to 600 liters of soil and about 2,000 liters of liquid fertilizer annually. This is not just waste disposal, but turning it into a useful resource, reducing pressure on the environment.
