MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133338 A) filed by Dr. Mahalingam College Of Engineering And Technology, Coimbatore, Tamil Nadu, on Dec. 30, 2025, for 'an artificial hexa tree for urban carbon dioxide removal.'
Inventor(s) include S. Mahalingam; Dr. T. Saravana Kannan; and R. B. Rajeshkumar.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "An artificial carbon dioxide (C02) removal system, a newHexaTree prototype is proposed to be used in urban and semi-urban areas. The system is formed using multiple hexagonal modules assembled into a vertical, tree-like structure, where each module holds a replaceable solid C02 capture material such as amine-based sorbents, activated carbon, zeolite, or metal-organic framework composites. The hexagonal design makes it easier for air to get in, makes the structure stronger, and makes it easier to expand, so the system can be used in different places. Air from the outside world flows through the structure naturally or with the help of low-power ventilation. This arrangement enables effective interaction between the airflow and the carbon capture material. The system can be fitted with basic environmental sensors to monitor C02 concentration, . . temperature, humidity, and airflow for performance evaluation and maintenance planning. In one implementation, bio-sequestration units such as microalgae modules cab be added to utilize the captured carbon dioxide and generate oxygen. The proposed HexaTree prototype offers a practical, modular, and low-energy approach for carbon reduction in roadside areas, campuses, public spaces, and industrial surroundings."
