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.

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.
