MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641018303 A) filed by Sri Krishna College Of Engineering And Technology, Coimbatore, Tamil Nadu, on Feb. 18, for 'eco bricks from marine waste and red mud for sustainable construction.'
Inventor(s) include Dr. R. Chandra Devi; Dr. D. Maruthachalam; Srikaviya S; Pooja N; Syed Mushtaq SJ; and Mustaq Ali M.
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: "The present invention provides a sustainable and eco-friendly masonry brick and a method for manufacturing the same. The brick composition uniquely utilizes industrial and marine waste, specifically red mud from aluminum production and seashell waste, as primary constituents. The invention includes a novel pre-treatment step involving low-temperature calcination (300-500 C) of a portion of the red mud and seashell powder to enhance their reactivity. The calcined and raw materials are combined with activators like hydrated lime and alccofine in specific proportions to form a homogeneous mixture. This mixture is molded and cured at low temperatures (105-110 C) without traditional kiln-firing, resulting in a brick with a compressive strength of approximately 9.064 N/mm, comparable to conventional bricks. The invention offers a low-carbon, energy-efficient solution for converting hazardous and nuisance wastes into high-performance, durable construction materials, addressing environmental challenges and promoting a circular economy in the building sector."
