Mycelium Bricks
Context
With rising concerns about climate change, the construction industry is exploring sustainable alternatives to reduce its carbon footprint. A significant focus is on mycelium bricks, an innovative bio-material derived from fungi, which could potentially replace conventional fired clay bricks.
About Mycelium Bricks:
- Mycelium is the vegetative part of fungi, composed of branching filaments.
- Mycelium bricks are made by combining sawdust, husk, and fungal spores, which solidify into a lightweight, fibrous network.
- Advantages of Mycelium Bricks
- Sustainability: They are fully biodegradable and has a lower carbon footprint than traditional bricks.
- Traditional brick production emits nearly 300 million tonnes of CO? annually.
- Lightweight: They are easier to transport and handle.
- Fire Resistance: They are naturally fire-resistant, reducing fire hazards.
- Good Insulation: They offer better heat insulation than conventional bricks.
- Versatile Uses: Potential applications in interior design, liquid filtration, circuit boards, and sports equipment.
- Sustainability: They are fully biodegradable and has a lower carbon footprint than traditional bricks.
- Challenges of Mycelium Bricks
- Structural Strength: Lower load-bearing capacity compared to concrete and fired bricks.
- Moisture Sensitivity: Highly absorbent and prone to fungal decay in humid environments.
- Durability Issues: Biodegrades within a few years, requiring further treatment.
- Production Constraints: Large-scale manufacturing is currently expensive due to limited infrastructure.
- Market Acceptance: Consumer skepticism and lack of awareness about its long-term viability.
- India-Specific Concerns
- Tropical Climate: High humidity and monsoons increase susceptibility to moisture damage.
- Termite Vulnerability: Unlike synthetic materials, mycelium is prone to pest attacks.
- Higher Costs: Limited production facilities make it a costly alternative for now.
