Greenwater Scientific Develops Algae-Based Indoor Air Purifier Recognized in US and India
Greenwater Scientific, founded by an Indian undergraduate at UC San Diego, developed greenwaterHOME, a technology using microalgae to absorb carbon dioxide and produce oxygen in sealed rooms. Recognized with awards including a Grand Prize at UC San Diego and support from a U.S. Congressman, the system combines biological photosynthesis with a three-stage filtration to improve indoor air quality. This innovation addresses the issue of closed windows trapping carbon dioxide indoors, especially in polluted metropolitan areas where ventilation is limited.
