Algae are small climate savers. Even in their natural state they are extremely efficient photosynthesizers and absorb ten times more carbon dioxide (CO₂) than land plants. In bioreactors equipped with appropriate sensors, control technology and automation, the efficiency of algae can be increased to a hundred times that of land plants. This shows that they have a significant potential for a climate-neutral circular economy. With the PhotoBionicCell research project Festo demonstrates a potential approach for the industrial biologisation of...
