Photo bioreactor from Fraunhofer FEP at lab scale to culture cyanobacteria under defined light, temperature, and gas conditions
Fraunhofer researchers have developed a method of creating biogenic construction materials based on cyanobacteria. The bacteria multiply in a nutrient solution, driven by photosynthesis. When aggregates and fillers such as sand, basalt, or renewable raw materials are added, rock-like solid structures are produced. Unlike traditional concrete production, this process does not emit any carbon dioxide, which is harmful to the environment. Instead, the carbon dioxide is bound inside the material itself.
