Geological Microbial Formations

Geological Microbial Formations explores biocementation as a transformative approach to converting construction waste into architectural materials. It combines biotechnology, robotic fabrication, and architecture to leverage biomineralisation—a process where microorganisms precipitate calcium carbonate (CaCO₃) minerals. Sporosarcina pasteurii, a microbial calcium carbonate precipitation (MICP), binds aggregates into solid structures under low-energy conditions. The installation features a robotic arm mimicking stromatolite formation, depositing aggregates and spraying bioactive agents. Visitors witness dynamic material growth alongside completed artifacts, and microscopic visualisations highlight the intricate biological and biochemical processes involved. Geological Microbial Formations reimagines material processes and cycles, fostering a critical dialogue about the role of biotechnology in developing new sustainable and interdisciplinary practices within architecture.
