Philippe Fonta, Managing Director, Cement Sustainability Initiative

The Cement Sustainability Initiative (CSI) is a global effort by 24 major cement producers with operations in more than a hundred countries who believe there is a strong business case for the pursuit of sustainable development. Collectively these companies account for around 30 per cent of the world’s cement production and range in size from very large multinationals to smaller local producers. ICR interacted with Philippe Fonta, Managing Director, Cement Sustainability Initiative (CSI), to know more about the organisation and how the Indian cement industry can benefit from it. Excerpts from the interview.

Tell us about CSI, its objectives and its functioning.

CSI is a platform where we bring different cement manufacturers from different parts of the world to work on the best practices, share them with others and r help each other in implementing them to ensure sustainable development. In India, the plants are very modern with very efficient technology. India is probably more energy-efficient than some other parts of the world but there are some areas where we can do even better. For example, in terms of usage of alternative fuels for instance, India is a bit behind compared to other parts of the world. With CSI, we have room for discussion with other parts of the world, for co-operating and understanding how other countries have improved in this business and how we can improve as well.

How can we make the sector more sustainable?

With inputs from international energy agency, we have developed a road map which identifies the different levels in order to reduce CO2 emissions and to reduce the energy consumption in the process of cement manufacturing. And for that we have identified four levels, one is improving energy efficiency to all the technology in place, second is the use of alternative fuels, third is the limestone to cement ratio if we can reduce the limestone in the cement which we use by using all sorts of materials like fly ash in cement and the fourth one is carbon capture or carbon capture and utilisation. We are also looking at biologically transforming captured carbon into algae and then using algae as alternative fuels for all the sectors.

What are the objectives of the CSI`s communication arm?

The first objective is to make sure that our members in India are well aware of the activities of CSI in terms of sustainable development. As CSI is a CEO-led organisation, the communication happens at a corporate level on a global scale. We have to make sure that the objectives are met at an operational level and that they (CEO) know what it means in terms of requirements and commitment.

The other objective is to work on image building of the cement sector. The world over, the perception of the cement and concrete sector is a bit skewed. Cement is perceived as something which is dirty, not responsible, in the way it is produced with regards to the environment, which is not the case. So we have to re-establish the correct picture on that.

Thirdly, we want to have the leading companies in CSI, the ones who are really driving the process Our interest is not to have all the cement manufacturers worldwide, but if we can expand what we are doing, we may attract some additional companies in the country who are interested in sustainable development and who don’t have the expertise, or who are already doing things and would like to share it with the group.

How do you persuade the member companies to share their knowhow openly with their competitors?

Yes, we understand that we are in a very competitive market and there are some elements which cannot be openly shared or openly exchanged between the members because of anti-trust issues, etc. But we are offering a platform where we can share the knowledge without the need to share critical business information.

For instance, we have a database which is called Getting the Numbers Right. The GNR database has numbers pertaining to CO2 emissions and energy consumption of the members at a detailed level. This helps in comparing performance of various types of technology, the volume of market, etc. Clearly, this cannot be exchanged between one member and another. So we are having a third party to facilitate this exchange, which has a confidentiality agreement with each member. They take the data, mix them together and present an aggregated form. So you cannot identify which competitor has given the information but at least you can see how your own performance compares to that of others in the sector.

The data on the website is for 2012? How frequently is this data updated?

It is updated every year but for anti-trust reasons we keep a gap of one year. So in May 2014 we will publish the data we have collected in 2013 which is basically 2012 data. In 2014, you actually get the 2012 data, in 2015 you will get 2013 data. This one- year buffer gives us more relief in terms of anti-trust issues.

How does CSI help companies to improve their compliance to sustainability index?

We have several ways of helping the companies. First, we have a series of crash courses in which every company who is a member of CSI is invited to participate. These crash courses serve as a platform to share information, discuss with their peers and understand and share best practices. I would say that the beauty of CSI is that companies are being trained by other companies. In other words, some companies are training their competitors, because in the end what is important is that the sector is improving. It’s really a collaborative effort and I tend to think that the challenge of sustainable development is so huge that one single company cannot solve it alone. Even the companies in CSI cannot solve it alone. So we need collaboration and that’s why we need more companies to be involved but also we need to work with trade associations. We are working with CMA, and CMA is helping to spread our message. Through the work that we are doing with the trade associations and also other stakeholders, we are trying to reach the policy- makers to tell them what we are doing and to make them understand how we need them to help us implement the solutions. Even a company who is not a part of CSI has access to its documents. Globally this collaborative approach can make the difference.

How does a company become a CSI member?

We have a charter at CSI in which we have a list of commitments that the company has to fulfill. So when a company is interested in joining, they have to follow the process in three steps. First they have to sign a letter from their CEO to express their interest in joining and to explain what they have already done in terms of sustainable development. So, it’s at CEO level, it cannot be someone from the board. Then the company has to have a sustainable development report on their website which explains what they are doing in terms of sustainable development. And thirdly, we send the company a checklist with regards to all the commitments we have in the charter. It does not mean that the company has to be fully compliant at the day of joining. The aim of this check list is just to do a self- assessment or gap analysis between where the company stands in terms of developments and where the commitments are. This is done by the company and sent back to CSI. Then, CSI is governed by core members evaluate the self assessment coming from the company. If they are confident that in three years of joining, the new member will be fully compliant with the charter then the company is accepted. If the core Chair thinks it will be hard in the next three years for the company to be compliant, then we request the company to keep improving and come back next year.CSI by no means an exclusive club. It’s just that we have some criteria and that the companies have to fulfill the criteria. And when the company joins, the existing members try to help the company fulfill their commitments in the next three years. We are going to start and audit process this year for the existing members and for members who have joined for more than four years in order to make sure they are compliant. And if we identify some gaps, we help them to be compliant.

Naveen Kumar Sharma, AVP – Sales and Marketing, Toshniwal Industries, talks about redefining instrumentation with customised, digitally enabled solutions engineered for harsh plant environments.

For over six decades, Toshniwal Industries has played a pioneering role in advancing process instrumentation for Indian manufacturing. In this exclusive conversation with Kanika Mathur, Naveen Kumar Sharma, AVP – Sales & Marketing, explains how the company designs kiln and grinding plant solutions tailored to the unique demands of the cement industry. As plants transition to higher AFR use and smarter automation, Toshniwal’s technologies offer greater reliability, accuracy and predictive insight.

Tell us how are your process instruments and condition monitoring system customised for cement kilns and grinding plant operations?
Toshniwal is a company with a legacy of over 65 years, and our experience has taught us that cement kilns and grinding units are fundamentally different in their operational demands. As an Indian company, we understand the unique requirements of Indian cement manufacturers. We work closely with our customers, engage deeply with their technical teams, and study operational challenges in real-time.
Based on these insights, we customise our solutions for both kiln and grinding applications. This tailoring is not just at a product level, but at a solution level—engineering design, instrumentation logic, and process optimisation. Our primary objective, for both the industry and our customers, is to reduce yield loss. Every customisation we implement is driven by this goal. We engineer smarter systems to reduce waste, improve consistency and increase plant reliability.
Ultimately, our solutions are built on an understanding that cement manufacturers require robust, practical and maintainable instruments. We design with this mindset so plants can operate more efficiently, with better control and higher profitability.

With the rising use of AFR, how do your solutions support thermal zone reliability and process time?
Our solutions are built around four core parameters: energy efficiency, yield loss reduction, product quality and environmental responsibility. These pillars drive our engineering decisions and define how our technologies support cement plants, especially as they adopt alternative fuels and raw materials (AFR).
We strongly believe in energy conservation. Every product we offer—whether for thermal monitoring, kiln control or flame optimisation—is engineered to improve energy performance. Reducing yield loss is another principle deeply embedded in our solutions, because production interruptions and material losses directly affect plant profitability and clinker quality.
We are also highly conscious of the end-product quality delivered by our customers to their markets. Consistency in burning, heat transfer, and thermal profiling directly influences clinker characteristics, and our instruments help maintain this stability.
Lastly, and most importantly, we care about the environment. We want to leave a greener world for the next generation. This mindset aligns with India’s digitalisation movement, advocated by our Prime Minister. Digital technologies are crucial for optimising AFR use, process stability, emissions and kiln efficiency. We are proud to contribute to this transition.
By optimising flame patterns, energy use, and pollution, our solutions deliver direct and indirect savings. Plants benefit from lower operational losses, reduced maintenance, and improved reliability, especially in pyroprocessing zones.

Tell us how do you address harsh environment challenges in cement plants, say dust, temperature, etc. with your sensor and monitoring?
This is a very important question because cement plants, steel plants, and power plants operate in extremely harsh environments. There are two major categories of specifications that we must respect while designing solutions: technical specifications and environmental specifications. Technical specifications relate to performance accuracy, measurement integrity, responsiveness and process safety. Environmental specifications, on the other hand, relate to high temperatures, heavy dust, humidity, vibrations and corrosive atmospheres. Our solutions are engineered to withstand both. We customise sensors, housings, mounting mechanisms and protective systems so that our instruments operate at 100 per cent functionality in harsh conditions. We ensure that the plant experiences minimal downtime from our systems. That is our engineering philosophy—solutions must work reliably in real-world environments, not just in ideal laboratory conditions.

What retrofit pathways do you offer for older cement lines to upgrade measurement and monitoring systems and how is the Indian market responding?
Every solution we provide is scalable and digitally adaptable. Technology evolves rapidly, and our offerings evolve with it. When we upgrade instruments or monitoring systems, we design them to integrate with existing plant infrastructure, so customers do not have to rebuild everything from scratch. Once our solution is installed, software upgrades or performance improvements can often be deployed without major cost. This ensures that customers continue to benefit from ongoing technological advancements. The Indian market has responded positively to this approach. Plant operators appreciate solutions that are future-ready and dynamic rather than static. Scalability helps them maintain competitiveness, extend asset life, and move toward smart manufacturing with confidence.

So how is your organisation leveraging digital technologies in your instrumentation portfolio for cement plants?
Digitalisation is at the core of every product we manufacture. We stand firmly behind the digital movement, not only because it represents efficiency, but because it is the direction in which the Indian industrial ecosystem is evolving. We deploy machine-vision technologies, advanced inline monitoring systems, and solutions capable of visualising the
inside of the furnace. These systems help reduce downtime, enable predictive asset management and provide actionable analytics to customers. All our technologies communicate seamlessly with Level 1, Level 2, and Level 3 automation. This allows integration across SCADA, DCS, ERP, and cloud ecosystems. Digitalisation for us is not an add-on—it is foundational to how our instrumentation is built.

What are your key innovation priorities to help Indian cement plant producers hit harder, higher substitution rates, lower emissions and smarter processing?
Sustainability is a national priority, and we are committed to supporting it. Our current portfolio already helps improve efficiency, reduce emissions, and support alternative fuel integration. But our innovation roadmap goes further. We are now developing specialised productivity-oriented software modules that will provide proactive alerts—not just alarms triggered after a fault has occurred. These modules will leverage artificial intelligence and machine learning to detect patterns early. The intention is to help plant teams take corrective actions ahead of time, reducing yield loss and environmental impact. Instead of informing the plant that a disruption has happened, the system will indicate that a disruption will happen, giving operators time to prevent it. We believe that within the next 12 to 18 months, we will launch these predictive solutions in combination with our instrumentation. When implemented, they will significantly improve decision-making, process stability and environmental performance across the Indian cement sector.

In this insightful article, KB Mathur, Founder and Director, Global Technical Services, explores how reclaiming used lubricants through advanced filtration and on-site testing can drive cost savings, enhance productivity, and support a greener industrial future. Read on to discover how oil regeneration is revolutionising sustainability in cement and core industries.

The core principle of the circular economy is to redefine the life cycle of materials and products. Unlike traditional linear models where waste from industrial production is dumped/discarded into the environment causing immense harm to the environment;the circular model seeks to keep materials literally in continuous circulation. This is achievedthrough processes cycle of reduction, regeneration, validating (testing) and reuse. Product once
validated as fit, this model ensures that products and materials are reintroduced into the production system, minimising waste. The result? Cleaner and greener manufacturing that fosters a more sustainable planet for future generations.

The current landscape of lubricants
Modern lubricants, typically derived from refined hydrocarbons, made from highly refined petroleum base stocks from crude oil. These play a critical role in maintaining the performance of machinery by reducing friction, enabling smooth operation, preventing damage and wear. However, most of these lubricants; derived from finite petroleum resources pose an environmental challenge once used and disposed of. As industries become increasingly conscious of their environmental impact, the paramount importance or focus is shifting towards reducing the carbon footprint and maximising the lifespan of lubricants; not just for environmental reasons but also to optimise operational costs.
During operations, lubricants often lose their efficacy and performance due to contamination and depletion of additives. When these oils reach their rejection limits (as they will now offer poor or bad lubrication) determined through laboratory testing, they are typically discarded contributing to environmental contamination and pollution.
But here lies an opportunity: Used lubricants can be regenerated and recharged, restoring them to their original performance level. This not only mitigates environmental pollution but also supports a circular economy by reducing waste and conserving resources.

Circular economy in lubricants
In the world of industrial machinery, lubricating oils while essential; are often misunderstood in terms of their life cycle. When oils are used in machinery, they don’t simply ‘DIE’. Instead, they become contaminated with moisture (water) and solid contaminants like dust, dirt, and wear debris. These contaminants degrade the oil’s effectiveness but do not render it completely unusable. Used lubricants can be regenerated via advanced filtration processes/systems and recharged with the use of performance enhancing additives hence restoring them. These oils are brought back to ‘As-New’ levels. This new fresher lubricating oil is formulated to carry out its specific job providing heightened lubrication and reliable performance of the assets with a view of improved machine condition. Hence, contributing to not just cost savings but leading to magnified productivity, and diminished environmental stress.

Save oil, save environment
At Global Technical Services (GTS), we specialise in the regeneration of hydraulic oils and gear oils used in plant operations. While we don’t recommend the regeneration of engine oils due to the complexity of contaminants and additives, our process ensures the continued utility of oils in other applications, offering both cost-saving and environmental benefits.

Regeneration process
Our regeneration plant employs state-of-the-art advanced contamination removal systems including fine and depth filters designed to remove dirt, wear particles, sludge, varnish, and water. Once contaminants are removed, the oil undergoes comprehensive testing to assess its physico-chemical properties and contamination levels. The test results indicate the status of the regenerated oil as compared to the fresh oil.
Depending upon the status the oil is further supplemented with high performance additives to bring it back to the desired specifications, under the guidance of an experienced lubrication technologist.
Contamination Removal ? Testing ? Additive Addition
(to be determined after testing in oil test laboratory)

The steps involved in this process are as follows:
1. Contamination removal: Using advanced filtration techniques to remove contaminants.
2. Testing: Assessing the oil’s properties to determine if it meets the required performance standards.
3. Additive addition: Based on testing results, performance-enhancing additives are added to restore the oil’s original characteristics.

On-site oil testing laboratories
The used oil from the machine passes through 5th generation fine filtration to be reclaimed as ‘New Oil’ and fit to use as per stringent industry standards.
To effectively implement circular economy principles in oil reclamation from used oil, establishing an on-site oil testing laboratory is crucial at any large plants or sites. Scientific testing methods ensure that regenerated oil meets the specifications required for optimal machine performance, making it suitable for reuse as ‘New Oil’ (within specified tolerances). Hence, it can be reused safely by reintroducing it in the machines.
The key parameters to be tested for regenerated hydraulic, gear and transmission oils (except Engine oils) include both physical and chemical characteristics of the lubricant:

  • Kinematic Viscosity
  • Flash Point
  • Total Acid Number
  • Moisture / Water Content
  • Oil Cleanliness
  • Elemental Analysis (Particulates, Additives and Contaminants)
  • Insoluble

The presence of an on-site laboratory is essential for making quick decisions; ensuring that test reports are available within 36 to 48 hours and this prevents potential mechanical issues/ failures from arising due to poor lubrication. This symbiotic and cyclic process helps not only reduce waste and conserve oil, but also contributes in achieving cost savings and playing a big role in green economy.

Conclusion
The future of industrial operations depends on sustainability, and reclaiming used lubricating oils plays a critical role in this transformation. Through 5th Generation Filtration processes, lubricants can be regenerated and restored to their original levels, contributing to both environmental preservation and economic efficiency.
What would happen if we didn’t recycle our lubricants? Let’s review the quadruple impacts as mentioned below:
1. Oil Conservation and Environmental Impact: Used lubricating oils after usage are normally burnt or sold to a vendor which can be misused leading to pollution. Regenerating oils rather than discarding prevents unnecessary waste and reduces the environmental footprint of the industry. It helps save invaluable resources, aligning with the principles of sustainability and the circular economy. All lubricating oils (except engine oils) can be regenerated and brought to the level of ‘As New Oils’.
2. Cost Reduction Impact: By extending the life of lubricants, industries can significantly cut down on operating costs associated with frequent oil changes, leading to considerable savings over time. Lubricating oils are expensive and saving of lubricants by the process of regeneration will overall be a game changer and highly economical to the core industries.
3. Timely Decisions Impact: Having an oil testing laboratory at site is of prime importance for getting test reports within 36 to 48 hours enabling quick decisions in critical matters that may
lead to complete shutdown of the invaluable asset/equipment.
4. Green Economy Impact: Oil Regeneration is a fundamental part of the green economy. Supporting industries in their efforts to reduce waste, conserve resources, and minimise pollution is ‘The Need of Our Times’.
