Anuj Khandelwal, Business Head, JK Cement, discusses his company’s technological odyssey in environmental stewardship, and how it changed the thought process of India’s cement sector.

In the realm of global construction, the cement industry stands as a vital pillar, albeit one burdened with a significant environmental footprint, contributing to 5-8 per cent of global emissions. JK Cement recognises the imperative role it must play in fostering sustainability, understanding that our long-term growth is intricately linked to advancing the sustainability agenda.

Commitment to Sustainability
JK Cement has undertaken a proactive stance by signing up for Science-Based Targets Initiative (SBTi)-based goals, committing to a robust 21.7 per cent reduction in specific gross CO2 emissions by 2030 compared to the 2020 baseline. These ambitious targets, already validated and approved by SBTi, signify a substantial stride toward a greener future. Remarkably, we have exceeded expectations, achieving a 16.3 per cent reduction in H1FY24 and poised to surpass our FY25 commitments of a 7.2 per cent reduction.

Challenges in the Industry
Understanding the unique challenges of the cement and lime industry is pivotal. Unlike many other industries, the majority of greenhouse gas emissions in cement production emanate not from energy use but from the raw materials themselves. Approximately 60 per cent of CO2 emissions result from limestone processing, necessitating a nuanced approach to sustainability across four dimensions:

  1. Reduce the need for energy-intensive materials
  2. Improve energy intensity
  3. Greenify sources
  4. Prevent release at the source

A Catalyst for Sustainability
Embracing the philosophy that technology is pivotal in the road to sustainability, JK Cement has strategically invested in technological advancements. Our sustainability journey revolves around three key technological pillars:

  1. Technological upgrades for lower energy intensity
    Upgrading manufacturing technologies and equipment has been instrumental in achieving lower energy intensity. Notable examples include the upgrade of older plants and kilns, such as Nimbahera L3 and Mangrol L2, with ongoing projects in Mangrol L1 and deployment of state-of-the-art Waste Heat Recovery Systems (WHRS) ensures maximal green power output across all our integrated units.
  2. Technological innovations for enabling usage of greener sources
    The substitution of traditional fuels and raw materials with green sources demands technological innovations. JK Cement has taken the lead in deploying a chlorine bypass system at our Muddapur plant to achieve over 35 per cent Thermal Substitution Rate (TSR). Upgrades in feeding systems across kilns facilitate higher TSR levels.
    These innovations are integral to our circularity agenda. By harnessing cutting-edge technology, we are redefining our processes, ensuring a more sustainable and environmentally friendly approach to cement production.
  3. Unlocking scale and navigating challenges with technology
    Scaling sustainability initiatives requires automation and digital solutions. This is a critical part of our capability build as we move towards the new clean-tech solutions offered.
    For instance, real-time power balancing solutions address the variability in green power generation profiles. Digital load and demand balancing solutions have increased the usage of green power, helping us achieve a remarkable 48 per cent+ green power mix for JK Cement in H1FY24.
    Similarly addressing challenges associated with quality variance in alternate fuels and impact on stable kiln operations required innovative solutions. NIR sensors for online quality testing enable precise control over the alternative fuel blend. In parallel, automated feedback loops helped ensure stable kiln operations even at higher TSR levels.
    Investments in digital quality control systems enable the incorporation of higher alternate raw materials, crucial for maintaining product quality amid the variability of alternate materials.
    Our investment in digital solutions not only underscores our commitment to sustainability
    but also positions us as industry leaders. By leveraging automation, we not only achieve environmental goals but also enhance operational efficiency and competitiveness. These technological interventions also showcase our dedication to overcoming challenges.
  4. The Road Ahead
  5. Technological innovation remains central to JK Cement’s future sustainability initiatives.
    After evaluating the underlying physical and technical limits of available technologies, our
    findings are that the three technologies available today can have a material impact on driving
    down carbon emissions from cement production by 2030. Therefore, our short-term focus is on the three groups of cost-saving technologies to drive the focus further:
    • Substitute Cementitious Materials (SCM), including LC3 Cement
    • Biomass and waste alternative fuels
    • AI for energy efficiency, predictive maintenance, quality improvement and cement logistic and fleet optimisation
    Similarly exploring avenues such as hydrogen (H2) utilisation and electrification, Carbon Capture, Utilisation and Storage (CCUS), carbon-neutral transport, CO2 capture in the built environment, and efficient concrete use will be pivotal in achieving our long-term goals and the basis of technological evolution in these.
    As we look to the future, the role of technology in sustainability cannot be overstated. Our commitment to exploring innovative solutions aligns with the ever-evolving landscape of sustainable practices, positioning JK Cement as a beacon of environmental responsibility in the cement industry.

Conclusion
In conclusion, JK Cement views technology as a catalyst for not only meeting but exceeding sustainability targets. As we navigate the complexities of the cement industry, we remain dedicated to pioneering sustainable solutions that redefine the role of technology in our environmental stewardship. Our endeavours are not just about cement; they are about shaping a sustainable future for generations to come.

The Confederation of Indian Industry (CII), through its Green Business Centre and Energy Efficiency Council, inaugurated the 16th Conference on Alternative Fuel and Raw Material Usage (AFR) in Goa on 27 October 2026. The two-day conference brought together more than 350 industry leaders, policymakers, waste management experts and technology providers to explore strategies for accelerating alternative fuel adoption in India’s cement industry.

Held under the theme ‘Preparation for Net-Zero: Alternative Fuels & Raw Material in Cement Manufacturing’, the conference focused on reducing dependence on conventional fuels, improving waste utilisation and strengthening circular economy practices across cement manufacturing operations.

E R Raj Narayanan, Chairman, AFR Conference 2026, and Business Head and Chief Manufacturing Officer, UltraTech Cement, highlighted the industry’s progress in alternative fuel adoption. He emphasised the need to scale implementation, strengthen supply chains and extend circularity beyond fuel substitution to alternative raw materials through technological innovation and industry collaboration.

Harish Adconkar, Managing Director, Goa Waste Management Corporation, highlighted Goa’s progress in scientific waste management and refuse-derived fuel (RDF) production. He stated that approximately 765,000 tonnes of RDF had been supplied to cement plants, contributing to an estimated displacement of 320,000–560,000 tonnes of coal. He emphasised the importance of consistent RDF offtake and stronger coordination between urban local bodies, waste management agencies and cement manufacturers.

Dr L P Singh, Director General, National Council for Cement and Building Materials, identified AFR as an important opportunity for decarbonisation and resource efficiency. Drawing parallels with the industry’s successful utilisation of fly ash, he stressed the need to address quality, technological and economic challenges to expand alternative fuel adoption.

Dr Sharad P Kale, Special Advisor to the Chief Minister of Goa and former Head of Technology Transfer and Collaboration at BARC, emphasised treating waste as a resource. He highlighted decentralised biodegradable waste processing, reduced food waste and improved resource recovery as essential measures for minimising landfill dependence.

Kiran Ananth, Executive Director, Energy Efficiency, Renewable Energy and Green Entrepreneurship, CII-Green Business Centre, noted that India’s cement production reached approximately 491 million tonnes in FY2025-26, while the industry’s thermal substitution rate (TSR) stood at 7.5 per cent, with around 7 million tonnes of alternative fuels utilised annually.

He added that the industry had invested over Rs 12 billion in co-processing infrastructure during the past six years. Improving RDF supply reliability and quality assurance would be crucial to maximising the utilisation of existing infrastructure and accelerating industrial decarbonisation.

The conference also featured discussions on advanced AFR co-processing technologies, waste pre-processing solutions and industrial best practices for improving fuel substitution and resource recovery.

A publication titled ‘From Waste to Kiln: Scaling the Use of MSW-Derived RDF in Indian Cement Plants’ was launched during the inaugural session. The report identified inconsistent RDF supply and quality as major barriers to achieving higher thermal substitution rates.

According to the publication, many cement kilns already possess the technical capability to achieve higher alternative fuel substitution. However, variations in RDF availability, moisture content, particle size and calorific value continue to limit utilisation. The report emphasised the need to strengthen waste segregation, pre-processing and aggregation systems to establish reliable RDF supply chains.

The conference’s second-day agenda includes discussions on innovative domestic and industrial waste management solutions, alternative raw materials for low-carbon cement and strategies to increase alternative fuel utilisation across India’s cement manufacturing sector.
