1.3. Bacteria-Grown Bricks.

Bacteria-grown bricks are a bio-inspired solution that uses bacteria to “grow” building materials. These bricks are made by mixing sand, bacteria, and nutrients in moulds. Over time, the bacteria consume the nutrients and bind the sand particles together, forming solid bricks. This process eliminates the need for energy-intensive brick firing, reducing carbon emissions associated with traditional brick production.

  • Challenge: Durability and Maintenance – One challenge with bio-inspired surfaces is ensuring their long-term durability and minimizing maintenance requirements. The replication of natural structures on building surfaces may require ongoing care to preserve their functionality and appearance.
  • Solution: To overcome this challenge, it is important to invest in research and development to enhance the durability of bio-inspired surfaces. This involves exploring new materials and surface treatments that can withstand environmental factors, such as weathering and pollution. Additionally, developing maintenance protocols and guidelines specific to these surfaces can help ensure their long-term performance and reduce the need for frequent interventions.
