MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641042743 A) filed by Raju Egala; and Sirisha Korrai, Visakhapatnam, Andhra Pradesh, on April 2, for 'sustainable cold-pressed eco-bricks employing high-volume coconut ash and chemical activation for enhanced structural performance.'
Inventor(s) include Sirisha Korrai; G. Tanuj Kumar; and K. M. Archana.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The current invention provides a cement free, cold pressed, eco-brick that can promote sustainable development in the construction industry. The system uses a binder replacement of 50-60 % of coconut shell and coir ash and a chemical activation process using lime and gypsum to activate pozzolanic reaction within a stone dust skeleton. The process also removes the need for kiln firing by utilizing a high pressure mechanical compression of 35 MPa; thus producing a product with a near zero carbon footprint, and a 15-20% reduction in brick weight. The experimental results have shown that the ultimate compressive strength is 7.98 MPa, which exceeds standard building codes and utilizes greater than 80% of total waste materials."
