- No flushing, water, or electricity is needed, making it ideal for remote or off-grid environments.
Production and Sustainability
- 600 litres of nutrient-rich compost are produced annually for use as soil enhancers.
- 2,000 litres of liquid fertilizer are generated per year, creating a closed-loop ecological cycle.
Design and Accessibility
- Modular structure includes cedar panels with antimicrobial properties, contributing to durability and hygiene.
- Wheelchair-friendly design improves accessibility and inclusivity.
- Minimal maintenance: only four service visits per year, compared to monthly visits for traditional composting systems.
A Scalable Global Sanitation Innovation
The MycoToilet provides a promising alternative to conventional chemical toilets, which often use harmful substances like formaldehyde. Its nature-inspired approach is especially beneficial for parks, off-grid areas, remote communities, and regions without sewage infrastructure. As a product of interdisciplinary collaboration between UBC’s architecture and microbiology departments and funded by organizations including NSERC, the project demonstrates potential for wider global impact.

World’s First Mushroom-Powered Toilet Transforms Human Waste Into Fertilizer
I’m excited to share details about a groundbreaking innovation from the University of British Columbia that’s revolutionizing sanitation technology. The MycoToilet represents the world’s first mushroom-powered, waterless composting toilet system, offering an unprecedented approach to human waste management through the power of mycelium.
How the MycoToilet System Works
Unlike traditional composting toilets or chemical alternatives, the MycoToilet operates through a sophisticated biological process powered entirely by mushroom networks. I find this system remarkable because it requires no additional water, electricity, or harmful chemicals to function effectively. The mycelium – the root-like structure of mushrooms – actively breaks down human waste through natural decomposition processes, converting what was once considered waste into valuable resources.
The system’s design capitalizes on the incredible efficiency of fungal networks, which have evolved over millions of years to decompose organic matter. This biological approach offers significant advantages over conventional sanitation methods, particularly in off-grid locations or areas with limited water access. The MycoToilet’s ecological design demonstrates how innovative sanitation solutions can work with natural processes rather than against them.
Impressive Production Capabilities
Once fully operational, UBC researchers expect the MycoToilet to generate substantial amounts of useful materials annually. The system’s production capabilities include several key outputs:
- Up to 600 litres of nutrient-rich compostable soil per year
- Approximately 2,000 litres of liquid fertilizer annually
- Complete elimination of waste disposal concerns
- Zero water consumption during operation
- No chemical additives required for processing
I’m particularly impressed by the system’s ability to transform human waste recycling into a circular economy model. Rather than viewing waste as something to dispose of, the MycoToilet treats it as a valuable input for soil enhancement and agricultural applications. This shift in perspective aligns with growing demands for sustainable sanitation solutions that support environmental health.
The implications for off-grid communities and environmentally conscious facilities are significant. Traditional sanitation infrastructure often requires extensive water systems and energy inputs, making it challenging to implement in remote locations. The MycoToilet’s self-contained operation removes these barriers while providing tangible benefits through its fertilizer production.
This innovative approach from UBC demonstrates how biomimicry and natural processes can solve complex human challenges. By harnessing the power of mushroom networks, the MycoToilet offers a practical solution that addresses sanitation needs while contributing to soil health and agricultural productivity.

How Mycelium and Microbes Break Down Human Waste
The MycoToilet operates through a carefully engineered biological system that relies on nature’s most efficient decomposers. At its core lies a mycelium-lined compartment that serves as both an odor absorption system and a foundation for aerobic decomposition of solid waste materials.
The Biological Partnership in Action
Mycelium forms the backbone of this innovative waste processing system. This dense root network of mushrooms creates an intricate web that works alongside thermophilic microbes to break down human waste efficiently. I find this partnership particularly fascinating because it mimics natural forest floor decomposition processes, where fungi and bacteria collaborate to transform organic matter into nutrient-rich soil.
The system demonstrates remarkable engineering by separating liquid and solid waste streams from the outset. While liquids are diverted for separate processing pathways, the fungi and microbes focus their digestive powers on solid materials, converting them into usable compost through controlled biological processes.
Enzyme Production and Odor Control
These biological agents produce specialized enzymes that tackle one of the most challenging aspects of waste management: odor control. The enzymes work by converting complex waste compounds into simpler, less volatile substances that don’t produce offensive smells. This biochemical transformation represents a significant advancement over traditional composting toilets that often struggle with odor management.
Laboratory testing has validated the system’s effectiveness in real-world conditions. Results demonstrate that this biological process removes over 90% of harmful odor-causing compounds, creating a more pleasant user experience while maintaining sanitary conditions. This level of odor reduction surpasses many conventional waste treatment methods and makes the system viable for residential and commercial applications.
The transformation process underwent rigorous field testing through a six-week pilot program at the UBC Botanical Garden. During this trial period, researchers monitored the system’s performance under actual usage conditions, measuring everything from decomposition rates to user satisfaction levels. The pilot confirmed that the mycelium-microbe partnership could handle regular waste loads while maintaining consistent performance standards.
Temperature control plays a crucial role in optimizing the biological activity within the system. Thermophilic microbes thrive in elevated temperatures, accelerating the breakdown process while ensuring pathogen elimination. The mycelium network helps regulate these conditions by creating microenvironments that support optimal microbial activity throughout the decomposition chamber.
This biological approach offers several advantages over mechanical waste processing systems:
- No manual turning needed – the system operates continuously without human intervention.
- Natural air channels – fungi create conditions that maintain aerobic decomposition.
- Odor prevention – aerobic conditions prevent the formation of unpleasant anaerobic smells.
The end product of this biological transformation process is nutrient-rich compost suitable for agricultural applications. The mycelium network breaks down complex organic compounds into bioavailable nutrients, while the microbes ensure complete pathogen destruction through controlled decomposition. This creates a closed-loop system where human waste becomes a valuable resource rather than a disposal problem.
Understanding how these biological agents interact provides insight into the system’s reliability and scalability. The mycelium establishes a stable foundation that supports diverse microbial communities, creating resilience against environmental fluctuations that might disrupt single-organism systems. This biological diversity ensures consistent performance across varying conditions and usage patterns.
The success of this biological waste processing system opens possibilities for broader applications beyond individual toilets. Space exploration programs could benefit from such self-contained biological systems, where traditional waste management infrastructure isn’t available. The mycelium-microbe partnership represents a sustainable approach to waste treatment that aligns with growing environmental consciousness and resource conservation goals.
Accessible Design Built for Parks and Remote Communities
I find the MycoToilet’s modular approach particularly impressive because it addresses a critical infrastructure gap in underserved areas. The self-contained unit arrives ready for deployment in locations where traditional plumbing simply isn’t feasible or cost-effective. Parks, remote communities, and urban environments without adequate sanitation infrastructure can now access a sophisticated waste management solution that doesn’t require complex installation procedures.
Universal Access and Durable Construction
The design team prioritized accessibility from the ground up, ensuring wheelchair users can navigate the facility comfortably. This consideration extends far beyond basic compliance—it demonstrates a commitment to serving diverse populations in remote settings where accessible facilities are often nonexistent.
The prefabricated timber panel structure offers significant advantages over traditional concrete or metal alternatives. Cedar forms the primary construction material, but the exterior receives a specialized charring treatment that transforms its surface properties. This process creates natural antimicrobial characteristics while dramatically improving rot resistance, crucial factors for outdoor installations exposed to varying weather conditions.
Above the main structure, a green roof serves multiple environmental functions:
- Local wildlife finds habitat space
- Native plants help the facility blend into its surroundings
- Reduces visual impact
- Supports biodiversity in areas where development might otherwise disrupt natural ecosystems
Smart Interior Features for Maximum Efficiency
Inside, sustainability drives every design decision. A strategically positioned skylight eliminates the need for electric lighting during daylight hours, reducing energy consumption while creating a more pleasant user experience. Natural light makes the space feel less confined and more welcoming than typical portable facilities.
The ventilation system combines passive and active elements for optimal performance. Cedar panels line the interior walls, but these aren’t merely decorative—they contain integrated mycelium that actively absorbs odors as part of the biological waste processing system. A low-power fan maintains consistent air circulation, ensuring the environment remains comfortable for users while supporting the mushroom cultivation process below.
This ventilation approach addresses one of the biggest challenges with traditional composting toilets: managing unpleasant odors that often make these facilities unacceptable to users. The mycelium integration creates a living filtration system that works continuously without requiring chemical additives or frequent cleaning.
The MycoToilet requires only four service visits annually, a dramatic improvement over conventional composting toilets that typically need monthly attention. This reduced maintenance schedule makes the system particularly attractive for remote installations where regular servicing presents logistical challenges. Facility managers can plan quarterly visits rather than monthly trips, reducing operational costs and minimizing disruption to users.
Each service visit focuses on:
- Harvesting processed soil
- Conducting basic system checks
The biological processing handles most maintenance automatically, while the durable cedar construction withstands extended periods without attention. This reliability proves essential for installations in areas where backup facilities aren’t readily available.
The modular design allows multiple units to be connected or configured according to specific site requirements. A small park might need just one unit, while a remote community could install several connected facilities to serve a larger population. This flexibility makes the system economically viable for diverse applications, from emergency relief situations to permanent infrastructure development.
Installation requires minimal site preparation compared to traditional sewage systems. The self-contained nature means:
- No underground piping
- No connection to electrical grids beyond basic power needs
- No ongoing supply of chemicals or additives
These characteristics make the MycoToilet particularly suitable for locations where conventional infrastructure development would be prohibitively expensive or environmentally disruptive.
Revolutionary Alternative to Chemical Toilets and Global Sanitation Crisis
Traditional chemical toilets rely on formaldehyde to break down human waste, creating a hazardous byproduct that requires specialized disposal methods. I find this approach fundamentally flawed because it transforms a natural resource into a toxic liability. The MycoToilet completely eliminates this problem by harnessing mushroom-based decomposition processes that convert waste into fertile soil without any harmful chemicals or dangerous residues.
The timing couldn’t be more critical. Nearly half of the global population currently lacks access to adequate sanitation facilities, creating widespread health risks and environmental degradation. Chemical toilet solutions often prove too expensive or logistically challenging for remote areas and developing regions. This innovative system addresses these limitations by operating completely off-grid while producing valuable output instead of hazardous waste.
Scalability and Environmental Benefits
The MycoToilet’s design allows for deployment across diverse environments and use cases. Consider these practical applications:
- Trail systems and national parks where chemical disposal creates logistical nightmares
- Remote construction sites and temporary installations requiring sustainable waste management
- Rural communities in developing regions lacking traditional sewage infrastructure
- Emergency response situations where rapid sanitation deployment is essential
- Off-grid residential properties seeking environmentally responsible alternatives
Beyond waste management, this technology reduces dependence on synthetic fertilizers that contribute to soil degradation and water pollution. The nutrient-rich soil output supports local food production and landscaping projects, creating a circular economy approach that benefits both users and surrounding communities.
User acceptance remains crucial for widespread adoption of any sanitation technology. The MycoToilet prioritizes comfort and aesthetic appeal while maintaining accessibility features that accommodate diverse users. This thoughtful design approach helps overcome the stigma often associated with composting toilets, making sustainable sanitation more appealing to mainstream audiences.
The environmental advantages extend beyond waste processing. Chemical toilet systems require regular servicing with specialized vehicles, contributing to carbon emissions and operational costs. MycoToilet installations operate independently, eliminating these transportation requirements while producing beneficial output that enhances local ecosystems rather than burdening them with toxic waste streams.
Research Partnership and Future Applications
The MycoToilet project represents an ambitious collaboration that spans multiple disciplines at the University of British Columbia. I can see how the research brings together expertise from UBC’s School of Architecture and Landscape Architecture (SALA) and the Department of Microbiology and Immunology, creating a unique intersection between design innovation and biological science. This interdisciplinary approach proves essential for developing technology that must function both as a practical sanitation solution and as an effective biological system.

This diverse funding portfolio ensures the project can pursue long-term development goals while maintaining academic rigor and practical focus.
Data Collection and Scaling Potential
Current pilot programs focus intensively on gathering performance data that will shape future iterations of the technology. Researchers track microbial and mycelial efficiency in waste decomposition processes, monitoring how effectively different mushroom species break down human waste into usable soil amendments. User experience data provides equally valuable insights, helping designers understand how people interact with this alternative sanitation approach in real-world conditions.
The team’s vision extends far beyond laboratory testing or campus installations. They see the MycoToilet as a scalable solution that could address sanitation challenges in underserved communities worldwide. This technology could prove particularly valuable in areas lacking traditional sewage infrastructure or water access, where conventional toilets aren’t practical options.
Environmental benefits drive much of the project’s momentum, as the system converts waste into valuable soil rather than requiring water-intensive treatment processes. Public health improvements represent another crucial outcome, especially in communities where inadequate sanitation creates disease transmission risks. The mushroom-powered approach offers a clean, odor-controlled alternative that doesn’t rely on chemical treatments or extensive maintenance requirements.
Future applications might include:
- Deployment in remote communities.
- Disaster relief situations.
- Off-grid locations where traditional sanitation systems aren’t feasible.
The technology’s potential for addressing global sanitation challenges while producing beneficial soil amendments positions it as more than just an innovative toilet – it represents a comprehensive approach to waste management that could transform how communities handle human waste disposal and soil enhancement simultaneously.
