NAMI’s Microalgae Technology

Ambient air purification

About Microalgae Technology

Global warming is caused by emission of greenhouse gases, 72% is caused by CO2 from automobiles, power plants and industries. Indoor CO2 concentration can vary from 500-600ppm and can even exceed 1000ppm in crowded indoor places, such as classrooms, conference hall. High level of CO2 can cause drowsiness, headaches and loss of attention. NAMI’s microalgae technology, with a high removal performance of up to 90% of inlet CO2, has been incorporated into green walls in a joint collaboration with Greentins Technology Limited. Microalgae are aquatic species which can carry out photosynthesis and absorb CO2 to release O2. Microalgae green wall serve to provide aesthetics in addition to the air purification in both indoor and outdoor environments.
