A company called aIgreen has developed a system using algae to absorb carbon dioxide from indoor air and convert the resulting biomass into biofuel.
The company aIgreen has developed a system that uses algae to absorb carbon dioxide from indoor air, aimed at improving air quality in enclosed spaces and reducing its effects on human health.
The system uses a bioreactor that keeps algae in constant motion, enabling it to absorb carbon dioxide through photosynthesis. The resulting biomass can be converted into biofuel using a process that consumes less energy than conventional methods.
