MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202517080618 A) filed by Washington State University, Pullman, U.S.A., on Aug. 26, for 'methods for carbon-capture within biochar.'

Inventor(s) include Shi, Xianming; and Li, Zhipeng.

The application for the patent was published on Sept. 26, under issue no. 39/2025.

According to the abstract released by the Intellectual Property India: "Methods for carbon-capture within a biochar are provided. The method includes mixing a biochar with an alkaline solution to form an intermediate mixture and exposing the intermediate mixture to a CO2 source so as to precipitate calcium carbonate onto and into the biochar to form a CO2 -weathered biochar. In some cases, the method also includes injecting CO2 into alkaline wastewater to sequester/store CO2 which can then serve as mixing water for producing cementitious composites. This method may be used to upcycle three waste streams, and treated CO2-wcathcrcd biochar preserves compressive strength of resultant concrete when substituted for a portion of the pre-cure cement and aggregate components. Further, treated CO2- weathered recycled aggregate preserves mechanical strength of resultant concrete when substituted for a portion of aggregate."

The patent application was internationally filed on Mar. 01, 2024, under International application No.PCT/US2024/018024.
