Bhopal's Future: Algae Trees Combat Pollution
13 May
Summary
- Algae tree purifies air by absorbing CO2 and releasing O2.
- One unit performs like 25 mature trees in pollution absorption.
- The device operates using solar energy and microalgae.
India has launched a novel climate innovation in Bhopal, Madhya Pradesh: an "Algae Tree." This bio-engineering structure, distinct from a natural tree, utilizes microscopic algae within a water-filled system to purify the air. Polluted air is drawn in, and the algae absorb carbon dioxide (CO₂) through photosynthesis, subsequently releasing oxygen (O₂).
The Algae Tree operates on solar energy, making it an eco-friendly system. Developers claim one unit can absorb approximately 1.5 tonnes of CO₂ annually, equating to the environmental benefit of 20 to 25 mature trees. This technology is particularly relevant for Indian cities like Bhopal, which grapple with rising emissions and limited green space.
While celebrated as an experimental climate technology, experts emphasize that the Algae Tree is an supplementary method and cannot replace the broader ecological contributions of natural forests. The system effectively traps dust and particulate matter, but the biodiversity impact of actual trees remains unparalleled.
