en.Wedoany.com Reported - Indian cement manufacturer JK Lakshmi Cement reviewed the progress of limestone calcined clay cement (LC3) technology and its commercial applications during a meeting, focusing on low-carbon alternatives to traditional cementitious materials. Compared to conventional cement, LC3 can reduce carbon dioxide emissions by up to 40%, a reduction that the company says helps drive industry decarbonization. JK Lakshmi Cement emphasized that it was one of the first two Indian cement manufacturers to put LC3 into commercial production after the Bureau of Indian Standards approved the technology as a cement standard.
Vinita Singhania stated that the transition of LC3 from research to commercial production reflects collaboration between industry, academia, and international institutions. Maya Tissafi acknowledged JK Lakshmi Cement's role in advancing LC3 adoption in India and its contribution to moving the technology from laboratory trials to commercial implementation. Both representatives emphasized the growing relevance of sustainable building materials as India's infrastructure and urban development expand.
The meeting explored ongoing collaborations with Swiss research institutions such as the Swiss Federal Institute of Technology Lausanne (EPFL), the Swiss Federal Laboratories for Materials Science and Technology (EMPA), and ETH Zurich, as well as Indian academic partners and development organizations. JK Lakshmi Cement has been involved in the LC3 initiative since 2014, with partners including EPFL, the Indian Institute of Technology Delhi (IIT Delhi), the Indian Institute of Technology Madras (IIT Madras), Development Alternatives, and Technology and Action for Rural Advancement. The company conducted one of the earliest industrial trials of LC3 and recently announced the commercial production of Green Pro LC3 cement at its Jaykaypuram plant in Rajasthan.
India remains the world's second-largest cement producer, with infrastructure expansion, urbanization, and housing demand continuing to support long-term industry growth, increasing interest in low-carbon technologies. JK Lakshmi Cement has an annual turnover of over INR 60 billion, with current cement capacity of approximately 18 million tons per year, targeting 30 million tons by 2030. In addition to gray cement, the company produces ready-mix concrete, gypsum plaster, wall putty, primers, adhesives, and fly ash blocks. The meeting concluded by emphasizing the need for continued collaboration to develop sustainable building solutions.
