Bhopal has introduced India's first algae tree, a bioreactor designed to capture carbon dioxide more efficiently than traditional trees. The system uses microalgae to absorb CO2 and release oxygen, with claims that one unit can perform the work of 25 mature trees. While the technology offers a compact way to reduce urban emissions, it raises questions about scalability and maintenance compared to natural reforestation. This installation represents a growing interest in urban bioreactors as tools for city-level decarbonization.
