How the Living Coffin Revolutionizes Eco-Friendly Burial
A mushroom-based innovation speeds decomposition, restores soil, and transforms human burial into a force for environmental renewal.
The Innovative Living Cocoon: Rethinking Burial
Emerging from the intersection of biology, technology, and sustainability, the Living Cocoon—often called the living coffin—presents a transformative approach to human burial. Created by Dutch designer and researcher Bob Hendrikx and his team at Loop, this novel coffin is crafted from mycelium, the intricate root network of mushrooms. By leveraging the natural decomposing power of fungi, the Living Cocoon not only accelerates the breakdown of human remains but also restores and enriches the surrounding soil. It marks a radical departure from traditional burial practices, seeking to reconnect humanity with the earth and promote a truly circular lifecycle. This article explores how the Living Cocoon works, its environmental advantages, production details, and its growing role in reshaping the funeral industry.
Why Traditional Burial Needs to Change
Conventional burial and cremation methods pose several environmental challenges:
- Slow Decomposition: Standard burial coffins, especially those lined with non-biodegradable materials, can delay the decomposition process for decades, sometimes up to 20 years.
- Chemical Pollution: Embalming fluids such as formaldehyde can leach into the soil, contaminating groundwater and local ecosystems.
- Loss of Resources: Coffins made from solid wood, metals, plastics, or decorative linings expend valuable natural resources and energy.
- Missed Ecological Opportunities: Human bodies and coffins, when properly managed, could instead serve as nutrients to revitalize depleted soils and foster biodiversity.
In light of these issues, there is growing interest in environmentally conscious alternatives, with the Living Cocoon emerging as a prominent and innovative solution.
What is the Living Cocoon?
The Living Cocoon is a biodegradable coffin formed entirely from mycelium. This fungal root network naturally decomposes organic matter, making it an ideal material for returning bodies to the earth swiftly and safely. Once buried, the coffin and its occupant become part of a larger ecological cycle, improving both the rate of decomposition and the quality of the surrounding soil.
Key Features
- Grown, Not Manufactured: Each coffin is cultivated over seven days by mixing mycelium with a natural substrate and shaping it in a mold.
- Passive Production: The growth process does not require external energy, heat, or light, minimizing environmental impact during production.
- Full Biodegradability: Both the coffin and body break down within two to three years, compared to more than a decade for conventional coffins.
- Soil Enrichment: The mycelium helps detoxify the earth, removing heavy metals and pollutants while enriching the soil for new plant growth.
How Mycelium Coffins Restore Nature
Mycelium is often called “nature’s recycler.” This web of fungal fibers digests organic material and breaks down complex compounds, including toxins and synthetic chemicals. By using mycelium as the primary material for coffins, the decomposition process is greatly accelerated, and the resulting byproducts actively contribute to soil remediation.
Research and tests by Loop and external partners, such as Ecovative, show that the Living Cocoon itself is absorbed into the earth in just 30 to 45 days under typical Dutch soil conditions. In contrast, it takes bodies buried in traditional caskets 10 to 20 years to fully decompose, largely because of impermeable coffin barriers and environmental toxins.
Main Environmental Benefits
- Detoxification: Mycelium binds and breaks down heavy metals and pollutants, cleaning the burial soil.
- Biodiversity Support: By improving soil quality, the coffin fosters healthier microorganisms, insects, and plant life.
- Renewable Cycle: The process returns nutrients to the earth, promoting the growth of trees and plants and effectively making cemeteries new sites of ecological richness.

How is the Living Coffin Made?
The fabrication of a Living Cocoon is a testament to nature-inspired innovation. The process involves:
- Mixing Materials: Selecting an optimal mycelium strain and combining it with organic matter—often wood chips—serves as food for the fungus.
- Molding: The mix is placed in a specially designed coffin-shaped mold.
- Growth Phase: Over about seven days, the mycelium colonizes the substrate, forming a lightweight but robust structure without external energy inputs.
- Drying: The completed coffin is dried to halt fungal growth, ensuring it is sturdy enough to hold a human body for burial.
Production is entirely passive, relying on natural fungal processes, thus minimizing manufacturing’s carbon footprint.
The Burial Process: From Cocoon to Soil
When a body is placed in the Living Cocoon and the coffin is interred, the burial process initiates a series of natural reactions:
- The mycelium reactivates upon contact with soil moisture and groundwater.
- Decomposition accelerates, typically taking two to three years for full body and coffin breakdown.
- Moss lining is often used within the coffin instead of synthetic fabrics, reinforcing the natural approach.
- The process avoids plastic linings, chemical dyes, and metals, all common in traditional caskets.
The result is a gentle, natural, and cleansing return to the earth, transforming human remains into a source of renewal for the local ecosystem.
Sustainability Certifications and Partnerships
The Living Cocoon is distinguished by several certifications and collaborations:
- Certified 100% Natural: Accredited by Cradle2Cradle Gold and GreenLeave for using only natural materials.
- Funeral Industry Adoption: Tested by Netherlands-based cooperatives CUVO and De Laatste Eer, with early burials already conducted.
- International Research: Ongoing scientific evaluation continues, including tests by US-based biotech firm Ecovative.
While Loop is still expanding its knowledge base about the effects on biodiversity, early indicators suggest substantial positive outcomes.
