Can you elaborate on the importance of logistics in cement industry?
Cement being a low cost and high-volume commodity, logistics is the most important part in cement industry as almost 30 per cent of the cost of cement is involved in logistics. But it is much more in the Northeast part of the country, since it is hilly terrain, transportation cost is very high, which can be more than 40 per cent of the cement price. Efficient logistics management has played a very crucial role in terms of the profitability, efficiency and delivery of the materials to last mile/end users. In short, logistics is a lifeline of the cement industry and you cannot imagine cement industry’s best performance without best logistics/supply chain management.

What has been the journey of logistics in the last 25 years? What specific changes have occurred other than the cost?
As per my view, the major changes in the last 25 years in supply chain management (logistics) are given under:
Globalisation:
The business landscape is rapidly becoming more global. Largely due to improvements in communications, globalisation is dramatically impacting the way business is managed and transacted, even on the most local levels. No area of a business is more affected by the trend to a global business environment than the supply chain. Manufacturing, distribution, sourcing of materials, invoicing and returns have all been significantly impacted by the increased integration of a global customer and supplier base, and many companies find that existing processes and technology are not flexible enough for this new business environment.

The right supply chain design is critical to managing the changes brought about by rapid globalisation. The thought-out supply chain network design can optimise the supply chain network and the flow of materials through the network. In doing so, network design captures the costs of the supply chain with a "total landed cost" perspective and applies advanced mathematical technology to determine optimal answers to both strategic and tactical questions.

Demand driven manufacturing and supply chain management: The capacities for manufacturing have increased, more companies have moved away from focusing efforts on plant-level production planning and are adopting more of a demand-driven focus of trying to influence and manage demand more efficiently. Rationalising what your company is best at selling, making and delivering, and aligning the sales force with that mindset, is critical to adopting a demand-driven model.

The demand-driven approach can help a company create a more customer-focused mindset, without sacrificing operational efficiency. Ultimately, a demand-focused approach to planning can significantly improve demand planning and management efforts and help overall costs and customer service efforts. Goals are then set to gain consensus on what will be sold each month for each product line or category and the resulting revenue. Of course, the driver of the demand review process is continuous improvement of forecast accuracy. Critical to the success of any demand plan is having all stakeholders, including sales, marketing, finance, product development and supply chain agree upon a consensus demand plan. It’s important for all participants to discuss factors affecting customer demand patterns Increased competition and price pressures: Historically, price, product features and brand recognition were enough to differentiate many products in the marketplace. With the continued commoditisation of many products, companies need better ways to distinguish themselves. Product innovation and brand equity no longer allowed them to command a higher price in the market. In order to continue to compete with that commoditised product the firm made significant cost improvements with supply chain redesign and technology.

Companies are looking to their supply chains in two ways to help offset this trend. First, they are looking at ways to reduce cost and are creating a more efficient value chain to remain cost competitive. Second, companies are looking at ways they can provide value-added services to meet the demands of more sophisticated customers. There are a number of ways suppliers can differentiate themselves and provide value and additional services and capabilities to their customers, such as:

  • Vendor managed inventory (VMI)
  • Radio frequency identification (RFID)
  • Packaging, and product differentiation
  • Express/seed deliveries of materials/products
  • Real-time information of materials monitoring
  • Companies should not only look to their supply chain to drive cost improvement but should increase capabilities as a means for staying competitive. Streamlining processes with better design, better collaboration across networks and new services will help your company stay competitive and strengthen relationships with your customers.

    Outsourcing: As many companies step back and examine their core competencies some realise that outsourcing in parts or entire supply chain can be advantageous. There can be significant economic benefits from outsourcing all or part of your supply chain operation, but without the right systems, processes or organisational management structure the risk to success can increase to frightening levels. In an outsource-heavy environment, companies need to put more controls and systems in place to compensate for the fact that the supply chain capabilities no longer reside onsite. In an outsourced supply chain environment the need for information, controls and excellence from the information worker becomes a high priority.

    Complex product lifecycles: Many companies are under pressure to develop innovative products and bring them to market more rapidly while minimising cannibalisation of existing products, which are still in high demand. In order to meet the needs of both customers and consumers, companies need more efficient product lifecycle management processes. This includes heavy emphasis on managing new product introduction, product discontinuation, design for manufacturability and leveraging across their entire product and infrastructure characteristics.

    As the economy becomes more global, compliance to packaging requirements and regulations have become critical to success. Without adherence to local packaging regulations a product may violate local requirements, preventing it from being distributed and sold in that market.

    Product lifecycle management (PLM) technology processes can help ensure that products being produced and targeted for specific markets are well-managed and are compliant. PLM tools and processes have helped consumer goods companies with their efforts to try to continually drive demand through packaging innovation and design. Implementation of an optimal PLM process and technology can allow a consumer goods company to effectively produce and distribute products that are only targeted for regional promotions or consumer preferences.

    Strong relationship between supply chain and customers: As supply chains continue to develop and mature there has been a move towards more intense relationship between customers and suppliers. The level of relationship goes beyond linking information systems to fully integrating business processes and organisation structures across companies that comprise the full value chain. The ultimate goal of relationship is to increase visibility throughout the value chain in an effort to make better management decisions and to ultimately decrease value chain costs. With the right tools, processes and organisational structure in place collaboration provides key people throughout the value chain with the information needed to make business-critical decisions with the best available information.

    Relationship is seen in the increased focus around RFID. Value chain leaders are looking at functional areas to better integrate the supply chains of their partners with themselves and RFID can serve as a means to quickly and efficiently ensure that critical product information is communicated as products flow thru the value chain and ultimately to the consumer.

    Companies that expand the usage of sales and operations planning have greater visibility across their owner enterprise and respective value chain, gain the agility necessary to improve the PLM process, improve promotional planning, minimise unnecessary build-ups of inventory, increase revenue predictability and execute customer service expectations.

    The role of technology in supply chain management: As supply chain networks have become more complex the need for greater and improved supply chain technology solutions has become critical. Enterprise resource planning (ERP) and best-of-breed supply chain management (SCM) solution providers have made significant investments in developing solutions to address the needs of manufacturing and distribution companies in areas in last 25 years, such as:

  • Network and inventory optimisation
  • Product lifecycle management
  • Sales and operations planning
  • Manufacturing optimisation
  • Logistics optimisation
  • RFID
  • Procurement
  • Business intelligence
  • Automation of warehouses, packers, weighbridges and fast tags at toll plaza etc.
  • These technologies have enabled the supply chain information worker to innovate, drive cost reductions, improve service and meet customer expectations better than ever. In order to have sustainable improvement in supply chain performance a business must have the right balance of investments in organisation, processes and technology. Lack of investment and focus in any one of these areas will reduce a company’s ability to achieve fundamental, sustainable improvement.

    Developing, manufacturing and selling a product can challenge the best organisations in the best of times. As a company’s business driver’s change, business processes, SCM technology investment and the overall approach to supply chain management must change and keep pace. An inefficient and poorly functioning supply chain can negatively impact every aspect of an organisation, jeopardising the long-term performance and success of a business.

    Companies that re-evaluate their business and how the current supply chain structure supports the business’ from a strategy, process, technology and organisational perspective’ must focus on keeping their supply chain aligned with the overall business strategy. Resulting, the high productivity and efficiency of last mile delivery with competitive logistics cost.

    What is primary and secondary transportation?
    The primary transportation means materials or goods transport from manufacturing unit/plant to direct retailers, customers, end users and secondary transportation means transport of materials of goods from warehouses, port, market organiser, distributors and C&F agents to the direct retailers, customers and end users.

    Can you compare rail v/s road transport in terms of cost, time and impact on environment?
    Railways and roadways are considered the most crucial modes of transportation. The rails being the major medium initially, road transportation has dominated the industry over the past few years.

    The major highlights of comparison of rail v/s road transport as given below:

  • There is a monopoly of the Indian Railways when you transport goods by rail. You cannot bargain for better rates. This is not the case when you use the roads for transporting your goods. The heavy competition ensures that you can bargain for better rates. Road transportation is available 24 hours a day and is often more affordable than other methods of transportation.
  • The delivering and collecting the goods from the railway yards rests with you. When you use roadways to transport goods, you get door-to-door delivery. Shipping specialty services are not uncommon in the trucking industry either. Whether you are shipping dry freight; frozen, fresh, or refrigerated; heavy or oversized, there are an array of companies available to you.

    Alex Nazareth, Whole-time Director and CEO, Innomotics India, explains how plants can achieve both cost competitiveness and sustainability by lowering emissions, reducing downtime and planning for significant power savings.

    As one of the most energy-intensive industries, cement manufacturing faces growing pressure to optimise power consumption, reduce emissions and improve operational reliability. Technology providers like Innomotics India are enabling this transformation by combining advanced motors, AI-driven digital solutions and intelligent monitoring systems that enhance process stability and reduce energy costs. From severe duty motors built for extreme kiln environments to DigiMine AI solutions that optimise pyro and mill operations, Alex Nazareth, Whole-time Director and CEO, Innomotics India, explains how the company is helping cement plants achieve measurable energy savings while moving closer to their sustainability goals.

    How does your Energy Performance Contracting model typically reduce power consumption in cement plants—e.g., MWh saved?
    Our artificial intelligence-based DigiMine AI Pyro and Mill solutions developed specifically for the cement industry, supports our customers in improving their process stability, productivity and process efficiency. In Pyro, this is achieved by optimising fuel consumption (Coal / AFR), reducing Specific Heat Consumption and reduction in emissions (CO2, SOx and NOx) through continuous monitoring of thermodynamics in pyro and recommending set-points of crucial parameters in advance for maintaining stable operations.
    Within the mill, this is achieved by improving throughput, reduce energy / power consumption and maintaining stable operations on a continuous basis. Our ROI-based value proposition captures the project KPIs like reduction of coal usage, increase of AFR, reduction of specific heat consumption (Kcal / Kg), reduction of specific power consumption (KWH / tonne), reduction of emissions, etc., by a specific percentage. This gives clarity to our customers to understand the investment vis-à-vis savings and estimate the recovery time of their investment, which typically is achieved within one year of DigiMine AI Pyro and Mill solutions implementation.

    What role do digitalisation and motor monitoring play in overall plant energy optimisation?
    Motors are being used extensively in cement production, and their monitoring play crucial role in ensuring continuous operation of applications. The monitoring system can automatically generate alerts for any anomaly / abnormalities in motor parameters, which allows plant team to take corrective actions and avoid any major equipment damage and breakdown. The alerts help maintenance team to plan maintenance schedule and related activity efficiently. Centralised and organised data gives overview to the engineers for day-to-day activities. Cement is amongst the top energy intensive industries in comparison to other industries. Hence, it becomes critically important to optimise efficiency, productivity and up-time of plant equipment. Motor monitoring and digitalisation plays a vital role in it. Monitoring and control of multiple applications and areas
    within the plant or multiple plants becomes possible with digitalisation.
    Digitalisation adds a layer on top of OT systems, bringing machine and process data onto a single interface. This solves the challenges such as system silo, different communications protocol, databases and most importantly, creates a common definition and measurement to plant KPIs. Relevant stakeholders, such as engineers, head of departments and plant heads, can see accurate information, analyse it and make better decisions with appropriate timing. In doing so, plant teams can take proactive actions before machine breakdown, enable better coordination during maintenance activities while improving operational efficiency and productivity.
    Further using latest technologies like Artificial Intelligence can even assist operators in running their plant with minimal requirement of human intervention, which allows operators to utilise their time in focusing on more critical topics like analysing data to identify further improvements in operation.

These motors have ingress protection that prevents dust, moisture ingress and can withstand mechanical stress. These motors are available in IE3 / IE4 efficiency classes thereby ensuring lower energy consumption during continuous operation. These motors comply with relevant Indian as well as international standards.

    How do your SD Severe Duty motors contribute to lower emissions and lower cost in heavy duty cement applications?
    Severe duty motors enhances energy efficiency and durability in demanding cement applications, directly contributing to lower emissions and operational costs. With high-efficiency ratings (such as IE3 or better), they reduce power consumption, minimising CO2 output from energy use. Their robust design handles extreme heat, dust and vibration—common in cement environments—ensuring reliable performance and fewer energy losses.
    These motors also lower the total cost of ownership by reducing downtime, maintenance and replacement frequency. Their extended service life and minimal performance degradation help cement plants meet sustainability targets, comply with emissions regulations and improve overall energy management—all while keeping production consistent and cost-effective.

    What pump, fan or compressor drive upgrades have shown approximately 60 per cent energy savings in industrial settings and can be replicated in cement plants?
    In the cement industry, the primary high-power applications are fans and mills. Among these, fans have the greatest potential for energy savings. Examples, the pre-heater fan, bag house fan, and cooler fans. When there are variations in airflow or the need to maintain a constant pressure in a process, using a variable speed drive (VSD) system is a more effective option for starting and controlling these fans. This adaptive approach can lead to significant energy savings. For instance, vanes and dampers can remain open while the variable frequency drive and motor system manage airflow regulation efficiently.

    As energy costs continue to dominate the cement industry, efficiency and sustainability are proving to be vital components. MM Rathi, Joint President, Power Management, Shree Cement, explains the company’s long-term strategy is focused on cutting emissions while powering growth with renewable energy solutions.

    Energy efficiency has always been a cost-saving lever for the cement industry. Today, it is the backbone of sustainability and competitiveness. Cement manufacturers are under growing pressure to optimise consumption, diversify power sources and align with decarbonisation targets. Shree Cement has been at the forefront of this transformation, significantly scaling up its green power capacity and embedding advanced technologies across operations. In this exclusive conversation, MM Rathi, Joint President – Power Management, Shree Cement, shares insights on the company’s approach to energy efficiency, challenges in brownfield modernisation and long-term strategies for achieving net zero alignment.

    What percentage of your total operational cost is attributed to energy consumption?
    At Shree Cement, energy is one of the most significant components of production cost, accounting for nearly 30 per cent to 40 per cent of total operational expenses. Within this, thermal energy typically contributes around 20 per cent to 25 per cent, while electrical energy forms about 10 per cent to 15 per cent. The exact share varies depending on factors such as the fuel mix (coal, pet coke or alternative fuels and raw materials), the power source (grid-based or captive like solar, wind or thermal), raw mix quality, and regional fuel and electricity price variations. This makes energy efficiency and the adoption of sustainable power sources a key focus area, both from a cost and sustainability perspective.

    How has your company improved energy efficiency over the past five years?
    Over the past five years, Shree Cement has consistently invested in enhancing energy efficiency across operations. Our green power capacity, covering wind, solar and Waste Heat Recovery (WHR), has more than doubled from 245 MW in 2020 to 592 MW in 2025. All grinding units are now equipped with biomass firing facilities, reducing dependence on conventional fuels. From the project stage itself, we prioritise efficiency by selecting advanced technologies such as six-stage kilns with integrated WHR, CFD-designed plants, and equipment fitted with VFDs, centrifugal compressors and high-efficiency fans. We also review and upgrade equipment systematically, replacing fans, compressors, blowers, pumps, boilers and turbines with more efficient options. This continuous approach has reduced costs while significantly advancing our sustainability journey.
    What technologies or practices have shown the highest energy-saving potential in cement production?
    WHR stands out as one of the most effective solutions, offsetting a significant portion of electricity required for clinker production. Hot air recirculation has also proven highly beneficial in reducing heat losses. Additionally, regular energy audits help us identify opportunities for improvement and implement corrective measures in daily operations. Together, these practices play a critical role in optimising energy efficiency and driving sustainable operations.

    What are the key challenges in adopting energy-efficient equipment in brownfield cement plants?
    The biggest challenge is the significant upfront investment required for upgradation. Retrofitting existing facilities often involves complex civil and structural modifications, which add costs and extend downtime. Integration is another hurdle, as new high-efficiency equipment may not align seamlessly with older kiln systems, fans, mills or automation setups. These factors make the transition in brownfield plants more resource-intensive and time-consuming compared to greenfield projects.

    How do you measure and benchmark energy performance across different plants?
    We track key performance indicators such as specific heat consumption and specific power consumption for each unit, benchmarking them against internal and external standards. Thermal Substitution Rate (TSR percentage) is another critical metric, measuring the share of alternative fuels in the thermal energy mix. Internally, we benchmark performance across plants to encourage best practice sharing. Externally, we compare against national averages and align with the Bureau of Energy Efficiency’s PAT (Perform, Achieve, Trade) scheme, which sets Specific Energy Consumption (SEC) baselines and targets for cement plants. This multi-layered approach ensures continuous monitoring, improvement, and industry leadership in energy efficiency.

    What role does digitalisation play in achieving energy efficiency in your operations?
    Digitalisation is pivotal in driving energy efficiency at Shree Cement. IoT sensors integrated with SCADA and DCS systems allow real-time monitoring of parameters like heat consumption and energy use, moving beyond periodic reports. Our digital platforms consolidate plant data, enabling management to compare metrics such as SPC, SHC, kWh per tonne and kcal per kg across units in real time. This visibility supports data-driven decisions, faster corrective actions, and higher operational efficiency.

    How do government policies and incentives influence your energy-saving decisions?
    Government policies and incentives strongly shape our energy-saving decisions. The Perform, Achieve, Trade (PAT) scheme sets plant-specific SEC targets. Non-compliance incurs penalties, while compliance earns tradable energy-saving certificates. This ensures energy efficiency is both cost-driven and regulatory. Additionally, subsidies and viability gap funding for renewable energy projects in wind, solar and AFR co-processing help reduce payback periods and make energy-saving investments more viable.

    What is your long-term strategy for aligning energy efficiency with decarbonisation goals?
    Our long-term strategy aligns energy efficiency with India’s net zero 2070 goals. Key levers include improving efficiency, expanding green electricity, producing more blended cement, and increasing alternative fuel use. Today, more than 60 per cent of our electricity comes from green sources such as solar, wind, and WHR, the highest in India’s cement industry. Our blended cement products, which reduce limestone and fuel consumption, further lower emissions. These products are certified under the GreenPro ecolabel by CII, validating our sustainability practices and environmental standards.
