MYCELIUM BRICKS

As part of efforts to fight climate change, the construction industry is exploring eco-friendly materials like mycelium bricks to reduce carbon emissions and promote sustainability.

Mycelium Bricks

These are bricks made from mycelium combined with agricultural waste (like husk, sawdust) and fungal spores.

Mycelium is the vegetative root structure of fungi.
These are formed by growing a fibrous network that solidifies into a lightweight, biodegradable material.

What are Mycelium Bricks?

Mycelium is the root-like structure of fungi that grows beneath the soil.
Mycelium bricks are made by combining:

Mycelium spores
Agricultural waste (like sawdust, husk)
The mixture grows into a fibrous, solid form that becomes a lightweight and biodegradable brick.

Characteristics of Mycelium Bricks

Composition: Made from organic waste (husk, sawdust) and fungal spores.
Biodegradable: Decompose naturally, reducing landfill waste.
Fire-resistant: Naturally resistant to flames.
Thermal Insulation: Effective heat insulators, reducing energy needs for heating/cooling.
Lightweight: Easier to transport and handle than traditional bricks.
High strength-to-weight ratio but lower load-bearing capacity than concrete or fired bricks.
Short lifespan: Biodegrade within a few years.

Significance of Mycelium Bricks

Environmental Benefits
Carbon Footprint Reduction: Fired clay bricks emit ~300 million tonnes of CO₂ annually. Mycelium bricks use low-energy production.
Waste Utilization: Repurposes agricultural waste into construction materials.

Application

Construction: Interior panelling, insulation
Other Uses: Liquid filters, sports equipment, printed circuit boards.

Challenges

Structural Limitations: Cannot bear heavy loads long-term (strength 100x lower than concrete).

Degrades under prolonged heat/moisture exposure.
Durability Issues: Susceptible to moisture, termites, and fungal decay (especially in tropical climates like India).
Production Barriers: High costs due to lack of infrastructure.
It cannot be mass-produced yet.
