In the realm of alternative burials, one unique and eco-friendly option has been gaining traction: the mushroom suit burial, also known as a biomass burial or a mushroom death suit. This innovative approach to end-of-life care is not only intriguing but also raises important questions about our relationship with the environment and our mortality.
What is a Mushroom Suit Burial?
A mushroom suit burial is a type of green burial that uses the mycelium, the vegetative part of a fungus, to facilitate the decomposition of the body. The process involves wrapping the deceased in a suit made from mushroom roots, which are then placed in a growing medium, such as wood chips or sawdust, within a biodegradable coffin or shroud.
How Does it Work?
The mushroom suit, developed by the company Coeio, is made from the roots of mushrooms, specifically those of the Amadou mushroom (Fomes fomentarius). These roots, or mycelium, are dried and pressed into a fabric-like material. When the body is wrapped in the suit and placed in a growing medium, the mycelium begins to break down the body's tissues, accelerating the decomposition process.

In addition to speeding up decomposition, the mycelium also has the potential to cleanse the soil of toxins. This is because mushrooms have the ability to absorb and break down harmful substances, a process known as mycoremediation. This makes mushroom suit burials not only a more natural and eco-friendly alternative to traditional burials but also a potentially beneficial one for the environment.
Benefits of Mushroom Suit Burials
- Eco-Friendly: Mushroom suit burials are a more sustainable alternative to traditional burials, which often involve the use of non-biodegradable materials and embalming fluids that can harm the environment.
- Accelerated Decomposition: The mycelium in the mushroom suit can break down a body in as little as a few weeks, compared to the several years it can take for a body to decompose naturally in the ground.
- Potential Soil Remediation: The mushrooms used in the suit can help cleanse the soil of toxins, potentially improving the quality of the soil over time.
- Cultural Significance: For some, the idea of becoming one with the earth in a literal sense can be deeply meaningful and spiritually fulfilling.
Considerations and Criticisms
While mushroom suit burials offer many potential benefits, they are not without their criticisms and considerations. Some of these include:
- Cost: Mushroom suit burials can be more expensive than traditional burials, making them less accessible to some people.
- Availability: The mushroom suit burial process is not yet widely available, with only a few companies offering the service.
- Regulatory Challenges: The legality of mushroom suit burials varies by location, and some places may require additional permits or have specific regulations that need to be followed.
- Cultural Acceptance: Like any alternative burial practice, mushroom suit burials may face resistance from those who prefer more traditional methods.
Mushroom Suit Burials in the Context of Green Burial
Mushroom suit burials are just one example of the many innovative and eco-friendly alternatives to traditional burials that are emerging in the green burial movement. Other options include natural burial, alkaline hydrolysis (water cremation), and promession (freeze-drying). Each of these methods offers a unique approach to end-of-life care that is more in line with sustainable and environmentally conscious practices.

As our understanding of the environmental impact of traditional burials grows, so too does the demand for more sustainable alternatives. Mushroom suit burials, with their potential to accelerate decomposition, cleanse the soil, and provide a unique cultural significance, are a compelling addition to the green burial conversation.
