CARBELIM: AN IIT MADRAS INCUBATED CLIMATE-TECH MAKING BUILDINGS BREATHE AND CITIES COME ALIVE

Across the world's fast-growing cities, air pollution has become an invisible crisis.

- 

Rising CO₂ emissions, fine particulates, and industrial pollutants have turned urban air into a public health hazard. While mechanical filters and tree-planting campaigns provide partial relief, neither offers the scale or speed required for a climate-positive future.

That is where Carbelim steps in. Incubated at IIT Madras Incubation Cell and accelerated by IIM Lucknow EIC, Carbelim is reimagining the very air we breathe. Its innovation is simple yet radical: harness the world's most efficient carbon capturers microalgae to transform polluted city air into breathable oxygen and valuable bioproducts.

From Nature’s Blueprint to Urban Innovation

Founded by Dr. Karthika Gopi, a scientist-turned-entrepreneur with a PhD from UAE University in nature-based carbon sequestration, Carbelim fuses biotechnology, engineering, and sustainability to address one of humanity's most urgent challenges. At its core lies a bold vision: that every wall, façade, and home can become a living carbon sink.
