THE Green Company Rating System has helped us in effectively communicating to our stake holders about our commitment to sustainable growth, to reduce consumption of natural resources without jeopardising growth of the company, says CK Jain, Unit Head, Vasavadatta Cement, Sedam. In an exclusive chat with Agith G Antony, Jain elaborates on various aspects of sustainability initiatives taken by the plant which is the first one to be awarded Greenco Gold, by the CII for the year 2012-15 under the GreenCo, Green Company Rating System. Excerpts from the interview.

What were the major objectives of going through with the GreenCo Rating System by CII?

One of the most important reasons behind applying for the rating system was to understand our environmental performance on various aspects of environmental sustainability. This includes areas such as energy efficiency, water conservation, greenhouse gas emission, waste management, material conservation, recycling and recyclability, green supply chain, product stewardship, life cycle analysis, other areas like ventilation, biodiversity preservation, innovation, etc. Another major objective was to frame a long term roadmap on going green.

What were the major challenges involved?

VC has always been a believer of sustainable growth and has taken several initiatives on the ecological front. These initiatives helped in achieving GreenCo certification. However, the missing component was the meticulous system of documentation required for GreenCo certification. The certification system helped us in documenting the initiatives taken.

The system presented a challenge that turned into an opportunity for us to record our savings in terms of energy savings, water savings, and GHG emissions mitigation and track the results on a regular basis. GreenCo system has been designed with 30 per cent weightage for systems and 70 per cent weightage for performance and results achieved. This emphasises the fact that just having systems in place is not sufficient and requires actual implementation of initiatives and consequent savings in terms of natural resource conservation.

What are the tangible advantages of the rating system?

GreenCo gives energy efficiency 20 per cent weightage (200 out of total 1000 points). Energy costs also account for approximately 45 per cent of our expenditure.

The system emphasises on the need to have an energy policy, formation of cross- functional energy management cell, energy metering and monitoring systems, setting internal, national and international benchmarks and equipment wise efficiency monitoring. All these initiatives have a direct impact on the energy consumption of the plant as well as energy costs.

The second parameter under GreenCo was, water conservation encourages companies to avoid competition and conflict with the neighbouring communities for shared resources like water. The rating emphasises on the need to have a water policy, water management team, targets for reduction and benchmarks for reduction in consumption. This has helped the plant in understanding and preparing itself for the future to ensure availability of water for both the community and the plant operations.

The plant also has to pay huge amounts of money for disposing hazardous waste. GreenCo encourages companies to reduce, reuse and recycle and practice sustainable waste management practices. For all the other parameters like GHG mitigation, material conservation, greening the supply chain, the rating has given us several tangible benefits.

The rating system has helped us in achieving our objectives of understanding our environmental performance on various aspects of environmental sustainability and in framing a long term roadmap on how to be greener.

Do you think it is a value addition in terms of your marketing strategies?

Yes, most certainly. GreenCo, the Green Company Rating System, has helped us in effectively communicating to our stake holders about our commitment to sustainable growth, to reduce consumption of natural resources without jeopardising growth of the company.

We have been in the cement industry since the year 1983-84, with a rich experience of more than 30 years. In these years, we have encountered all sorts of challenges. These challenges have made the organisation even bolder and determined in its journey to be the best in the country.

We have built faith and trust with our clients and builders by taking various initiatives on the ecological front. GreenCo has helped us in reiterating these initiatives to the near-by communities, our customers, stakeholders and employees.

To what extent has this rating system helped the company to become more sustainable and green?

It’s the proud proclamation but not egoistic exaggeration that this rating system has helped the company to become more sustainable and green. Vasavadatta Cement keeps its eyes and ears always open and vigilant to international standards, conventions and treaties to grasp the spirit with mind and heart.

What is VC’s stated goal of reducing your carbon footprint?

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.

Which of your high-efficiency IEC low-voltage motors deliver the best energy savings for cement mills or fans?
Innomotics India offers a range of IEC-compliant low-voltage motors engineered to deliver superior performance and energy savings, particularly for applications such as cement mills, large fans, and blowers. Innomotics has the complete range of IE4 motors from 0.37kW to 1000kW to meet the demands of cement industry. The IE5 range is also available for specific requirements.

Can safe area motors operate safely and efficiently in cement kiln environments?
Yes, safe area motors are designed to operate reliably in these environments without the risk of overheating.

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.
