SCALE @ Chemtech 2026 ,UrjanovaC {carbon capture & utilization} @UrjanovaC

Summary

Key Points

• Urjanovak, an IIT Bombay startup, has developed a patented technology to capture carbon dioxide from both direct air (DAC) and industrial flue gases (point source). 0:32
• The absorbed carbon dioxide then reacts with calcium ions, precipitating into calcium carbonate, which can be further purified if needed. 1:42
• This technology offers significant advantages over traditional methods by requiring minimal energy, operating at room temperature, and having negligible catalyst loss over thousands of recirculation cycles. 3:12
• The core process involves a patented catalyst in an aqueous solution, specifically industrial wastewater or seawater, which chemically reacts with and absorbs the CO2 at room temperature. 3:22
• A key innovation is the ability to utilize readily available non-distilled water sources like industrial wastewater or seawater, enhancing sustainability and reducing operational costs. 4:16
• The produced calcium carbonate is a valuable end product that can be sold to various industries, including pharmaceutical, cosmetic, and cement, turning an environmental waste product into a revenue stream. 5:21
• The process demonstrates a high conversion ratio, yielding approximately 2.25 tons of stable calcium carbonate for every 1 ton of CO2 captured. 5:55
• Urjanovak's technology helps address India's calcium carbonate deficiency and enables companies to meet carbon credit and ESG compliance, transforming CO2 from an environmental liability into a business opportunity. 8:09
• This entirely 'Made in India' technology, researched and patented at IIT Bombay, utilizes non-hazardous, environmentally friendly materials, further enhancing its sustainable profile. 10:08
• The system is designed to be scalable and retrofittable for diverse industrial applications, with current deployments underway for refineries and other industrial groups. 11:16
