MUMBAI, India, Nov. 28 -- Intellectual Property India has published a patent application (202531108186 A) filed by North Eastern Regional Institute Of Science And Technology, Nirjuli, Arunachal Pradesh, on Nov. 7, for 'a composition and a sustainable method for achieving a significant improvement in strength of organic soil.'
Inventor(s) include Dr. Ajanta Kalita; Nabam Jumsi; and Prof. Ajay Bharti.
The application for the patent was published on Nov. 28, under issue no. 48/2025.
According to the abstract released by the Intellectual Property India: "A composition and a sustainable method for achieving a significant improvement in strength of organic soil. The present invention relates to a composition (100) of organic soil and a sustainable method (200) with the use of Sporosarcina pasteurii in a sustainable process of biocementation utilizing eggshell powder as a natural form of calcium as a sustainable alternative source of calcium carbonate to enhance the strength and stability of organic soil with a particular focus on the performance under freeze-thaw cycles. The process involves controlled curing and testing the UCS and CBR values of the composition under varying temperature conditions, thus providing a composition that delivers the best balance of bearing capacity, strength, durability, and permeability improvement in natural organic soils, leading to a 466% enhancement in CBR of the soil. Additionally, freeze-thaw cycles are applied to assess durability under temperature variation and enhancement of strength."
