Inventor(s) include Sre Adethya. V; Thanushree. G S; Isha Vaishnavi. E; Harini. T; and Keerthana. P.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "This study investigates the partial replacement of fly ash with bagasse ash and rice husk ash in the production of eco-friendly ily ash bricks. Agricultural wastes such as bagasse ash (from sugarcane) and rice husk ash (from rice mills) are produced in large quantities and often cause environmental problems when disposed of improperly. Using these waste ashes in brick manufacturing helps reduce pollution and promotes sustainable construction. In this project, fly ash bricks were prepared with different replacement percentages of bagasse ash and rice husk ash. The prepared bricks were tested for compressive strength, water absorption, density, and durability. The results showed that adding these ashes can improve certain properties of the bricks while also lowering production costs. The study concludes that bagasse ash and rice husk ash can be successfully used as partial replacements in fly ash bricks, making them a costeffective, sustainable, and environmentally friendly alternative to conventional bricks. This approach also supports waste recycling and reduces the burden on natural resources."
