In the face of climate change, the construction industry is seeking low-carbon alternatives, and mycelium bricks have emerged as a promising innovation. 

• Mycelium Bricks: Created from fungal spores, husk, and sawdust, mycelium bricks form a lightweight, fibrous structure with a low environmental impact compared to traditional fired clay bricks, which emit nearly 300 million tonnes of CO₂ annually. 
  • They are biodegradable, fire-resistant, lightweight, and good heat insulators, making them suitable for interior panelling, filters, and electronics. 
  • Potential applications include interior panelling, liquid filters, sports equipment, and electronic components. 
• Challenges Hindering Adoption: Mycelium bricks have low load-bearing capacity, high moisture absorption, and a short lifespan due to biodegradability and vulnerability to termites, making them less durable than concrete. 
  • Tropical weather conditions, high humidity, and lack of infrastructure  in India make large-scale manufacturing expensive and impractical. 
• Potential Solutions: Flame retardants and Ultra Violet Coatings can improve fire resistance and durability, while R&D and policy support can enhance competitiveness with clay bricks.
