Recent Advances in Bio- Brick Research
Mikrobially Induced Calcite Precipitation (MICP)
MICP harnesses urease-producing bacteria, such as Sporosarcina pasteurii, to hydrolyze urea and generate carbonate ions. In the presence of calcium ions, calcium carbonate crystals precipitate around the particles. When applied to a mixture of sand and organic waste (e.g., rice husk), MICP can produce bricks with compressive strengths of 4–10 MPa—suitable for structural use. Some formulations even exhibit self-healing properties: if cracks form, bacteria can be reactivated to seal them. Research at the University of Colorado Boulder has demonstrated viable MICP bio-bricks using recycled concrete aggregate and food waste.
