Sustainable mining is the buzzword for all industries depending on mined raw materials, especially the cement sector. It is, therefore, imperative that we take a closer look at its economic and environmental impact.
The focus on mining in the context of cement has more than one reason to be at the top of the agenda on sustainability. With the sheer growth of this sector as an extractive process that touches many aspects of the environment on the one hand, and leaves the livelihoods of the people associated in a state of quandary on the other, given that the life of the mine and that of the prosperity of the people get intertwined.
The narratives have changed from the mere lifecycle of the mineral deposit to the complete sustainability that includes an integrated and holistic approach to preclude economic, environmental and social value from mining and allied operations and supply chains for a large number of stakeholders.
Economic Repercussions
The prelude to this narrative is the understanding of stakeholder responsibilities at a time when some parts of the world, where the global extractive process for limestone, the key mineral for producing cement, has seen capacities being ramped up to serve the burgeoning rise of cement demand. As ballpark estimates suggest, for a 4 billion tonne cement output of the world, the limestone requirement stands at close to 2.8 billion tonnes, which is the highest mineral ore extracted every year from the deposits of the world, which happens to be the top cover of the earth’s surface.
Most of these deposits occur closer to forests, biodiversity and tribal populations, essentially places where economic progress has been slow. If one looks at the total extractive mineral output, one would be seeing a three-fold increase over the last four decades. From 1970 to 2017, the annual global extraction of materials tripled and the global use of materials is expected to more than double from 79 Gt in 2011 to 167 Gt in 2060. Minerals that are non-metallic, such as construction material, e.g., sand and gravel, represent more than half of the total use of materials by weight and their use is expected to grow rapidly in the coming years (from 35 Gt in 2011 to 82 Gt in 2060). Cement industry, coupled with the concrete that needs aggregates and sand, is a part of the extractive mining industry landscape, and thus the environmental and social impact of mining becomes a very important subject, if one adds these supply chains as well.
On the one hand, mining as an economic activity could be encouraging for the populace, it could end up with the ‘Resource Curse’ as well, as mines reach the end of cycle of the deposits. Thankfully at least for cement, we have a burgeoning downstream, mostly closer to the mining operations, where a vibrant downstream operation is established that employs larger sections of people and thus livelihoods are intertwined on a bigger scale through supply chains that crisscross. Apart from the building and construction industry, which requires 80 per cent of the extraction, we still have steel, agriculture and chemical Industries needing limestone mining for a number of reasons.
Keeping Track of Sustainability
Sustainability reporting, which is mostly voluntary reporting, is at the core of the sustainable initiatives, sometimes prompted by the Country Reporting guidelines and Environmental and Sustainability Goals (ESG) of 2015 or the Global Reporting Initiative (GRI). The investors also demand more disclosure on Sustainability Initiatives with clear mandates that can be verified through trends and data. However, the 2018 Responsible Investing Survey and the 2020 Responsible Mining Index cites lack of quantity and quality in the reporting so far. Stakeholders increasingly require information on the environmental and social impacts of mining at the mine-site level, and presented in the local context. Sometimes there is little use to look at headline numbers aggregated over many sites across countries. Focus on site level reporting that gives periodic data on a host of environmental and social impact of mining becomes the important indicator of progress.
Some of the sustainability indicators at the site level include:
- Impact on biodiversity: Number/percentage of sites with biodiversity management plans
- Description of significant impacts on biodiversity: Amount of land disturbed or rehabilitated and information on the use of biodiversity offsets
- GHG emissions and energy use: Amount of CO2e GHG emissions and mitigation measures and energy consumption and reductions
- Water management: Amount of water withdrawal by source and water sources significantly affected by withdrawal of water
- Health and safety: Number of accidents/deaths, information on training on health and safety management security / human rights and rights of indigenous peoples
- Number/percentage of reserves in or near areas of conflict: Number/percentage of reserves in or near indigenous lands and engagement processes in place
- Processes in place to prevent child or forced labour and impact on local communities and local community engagement
- Number of operating sites where resettlement took place, number of households resettled in each site and information on how their livelihoods were affected in the process
- Number/percentage of operations with local community engagement (including minority groups such as women), and/ or environmental/social impact assessments
- Number/percentage of operations with significant negative impacts on local communities – Proportion of spending on local suppliers
Apart from these, water and air quality and gender diversity in mining operations have become important pointers as well. For mining operations in cement, site remediation and rehabilitation become an area of focus as many mines have reached their end of life. One of the ways to enforce this has been to enforce some of these at the inception of the Environment Impact Assessment and Mining Permit stage itself. With the lack of site-specific reporting as evidenced in almost 90 per cent of the mining sustainability reporting, corporate level reporting is only a high-level aggregation of most of data, masking site level inadequacies, which has been pointed out in both the Responsible Investing Survey and Sustainable Mining Index 2020.
If one looks at the expansion of the scope for the building and construction industry, where only a smaller part is covered under the cement-limestone mining operations and the larger part falls under aggregates and sand mining operations, which remains uncovered by sustainability reporting as most of these fall under small scale industry structure,
absolving them of the detailed disclosure requirements. It is therefore to be concluded that for most developing nations, we still have a long way to progress as far as sustainable mining operations are concerned. The entire supply chain of mining operations for concrete / building and construction industry must be looked at where the suppliers of sand, gravel and aggregates must be brought under the same purview and this leaves a lot to be desired as these
supply chains have third party sourcing activities lacking the rigour of the bigger corporate entities like cement companies.

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’.
