MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202631007129 A) filed by North Eastern Regional Institute Of Science & Technology, Itanagar, Arunachal Pradesh, on Jan. 24, for 'a composition and a method of stabilisation of clayey soil using bio-polymer with microbial induced calcite precipitation.'
Inventor(s) include Dr. Ajanta Kalita; and Nisha Kumari Singh.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to the field of strengthening of clayey soil in the cold areas which are susceptible to frost action. More particularly, the invention provides an eco-friendly composition (100) and a method (200) for significant enhancement in strength of clayey soil. Due to the continuous freezing and thawing cycles in cold hilly regions, the 5 strength of the clayey soil reduces and the same can be stabilised by using a natural biopolymer i.e. guar gum and microbial induced calcite precipitates. The strength of the clayey soil undergoing freezing thawing can be stabilised by using microbial induced calcite precipitates (MICP). The invention discloses a composition of 0.5% guar gum and 1.0 OD MICP added to clayey soil resulting in enhancement in strength of the soil by 432.61% in 10 the first cycle of freeze thawing, and a method thereof."
