Which eco-friendly technique is being piloted in 2025 to conserve stone monuments using bio-consolidants derived from bacteria?
- Microbial Induced Calcite Precipitation
- Nanoparticle coating
- Laser cleaning
- Polymer sealing
Answer: Microbial Induced Calcite Precipitation
MICP (2025 pilot) uses bacteria to precipitate calcium carbonate, strengthening weathered stone without chemicals. Tested at Qutub Minar and Khajuraho, it offers sustainable alternative to synthetic consolidants.
