MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541134559 A) filed by Vallurupalli Nageswara Rao Vignana Jyothi Institute Of Engineering And Technology, Hyderabad, Telangana, on Dec. 31, 2025, for 'next-generation reinforcement materials utilizing eco-sustainable composite bars as alternatives to traditional tmt steel bars.'
Inventor(s) include Bagathi Harsha Vardhan; Boppana Narendra Kumar; Alapati Rahul; Challamalla Likhitha; Kirala Sahasra; and Askani Arun.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "This invention relates to a Sustainable Green Technology (SGT) Bar developed as an environmentally responsible alternative to standard Thermo Mechanically Treated (TMT) steel bars in concrete construction. The SGT Bar is comprised of a core of recycled plastic onto which E-glass fibers are helically wound and bonded with a polymer resin. The resulting reinforcing member is lightweight, corrosion-resistant, and mechanically durable. By reconstituting waste plastic into a structural material, the invention reduces reliance on steel production and significantly decreases carbon emissions from traditional reinforcement. Testing indicated that the bar supplies greater elongation at yield (about 32.9 mm) and a similar tensile strength to Fe550D-grade steel with a weight almost two-thirds less. The composite is resistant to deterioration from moisture, salt, and chemical exposure and is suitable for applications such as marine works, chemical plants, bridges, and precast components. The invention therefore provides a practical, durable, and sustainable reinforcement system supportive of long-life and low-maintenance concrete structures."
