Soundaram Ramanthan, Researcher, Centre for Science and Environment (CSE), speaks on the new environmental norms for curbing pollution from power plants, with specific focus on the treatment of fly ash.

The new environmental policy framework for power stations came into force from December 2015. What has been the response from the industry?
The industry is pushing back. Very less enthusiasm is seen among the power stations to implement the standards. An informal survey by CSE found that many power stations have little idea about the pollution control equipment needed by their plants to meet the new standards. Some are in early stages of hiring consultants or asking manufacturers for clarifications on how to undertake the process.

The success factor is the norm which aims to reduce air pollution in the power industry. Over 75 per cent of air pollution in India is due to industries, and air pollution due to coal-based power stations out of all the Indian industries is disproportionately large. Over 60 per cent particulate matter emission, 45 per cent sulphur dioxide, 30 per cent oxides of nitrogen and 80 per cent mercury emissions from the industrial sector are by coal-based power plants. Reducing the stack pollution load of coal-based thermal power stations would mean reducing about one-third of air pollution load in India.

However, money required for up gradation is a difficulty, given that state generation companies already have huge debts to repay. The coal cess should be diverted to ensure implementation of the norms. Also, in case of old power stations which have completed the useful life of 25 years, the remaining lifetime, efficiency, usefulness etc., should be assessed before more investments in pollution control.

Give us your views on the new fly ash transportation norms.
The new norm mandates power stations to transport fly ash free of cost, up to 100 km, for use in private projects and up to 300 km for use in government projects. According to CSE estimates, transport of fly ash up to 100 km by road costs around 4 paisa per kilowatt hour (kWh) of electricity generated, compared to current ash-disposal costs of around 3 paisa/kWh. Therefore, the amendment will not have a material impact on a power plant?s costs; it will significantly benefit fly ash brick manufacturers since fly ash costs are a major portion of their total manufacturing costs.

In fact, fly ash brick makers end up paying a much higher amount to procure fly ash from traders since they are often unable to get it directly from power plants, so the benefit to them may be even higher. The time period given by the Environment Ministry to comply with these provisions is December 31, 2017. The success factor can be measured only by 2018.

The notification calls the Ministry to form a committee to ensure implementation of the provisions of the Act. However, such a monitoring committee has not been appointed so far.

Is the policy regulation sufficient to encourage the use of fly ash instead of clay bricks? What can be further done to reduce the production of clay bricks?
As a measure to increase demand for fly ash, the notification mandates use of fly ash bricks in all government projects where built-up area is over 1,000 sq ft. And all the cities having a million and above population will have to amend their by-laws to use fly ash bricks mandatorily. CSE welcomes this move of the Ministry and considers this the first encouraging step towards increasing fly ash utilisation. There are 53 urban centres having a million and over population in India and they are responsible for 25-40 per cent of the country?s total brick consumption, i.e., up to 80 billion bricks annually. If these cities, as expected, resort to use of fly ash bricks by amending by-laws, this can lead to a cumulative increase in fly ash use by 80 million tonnes. However, a concerted effort is required; authorities at the municipality level should come forward to ensure implementation.

Lack of implementation has been a major factor for failure in meeting the 100 per cent fly ash utilisation target. Therefore, the Ministry must appoint ?fly ash monitoring committees? at the state and Central level, in compliance with the fly ash notification, 2009, and publish and put in the public domain – like on the Environment Ministry website – a monthly report of the activities of these committees. Four major end-use agencies – Ministry of Road Transport and Highways, Ministry of Rural Development, Ministry of Urban Development and Ministry of Housing and Urban Poverty – should be included in the Central monitoring committee.

Is the present policy strong enough in order to implement Continuous Emission Monitoring (CEM)?
Most of the industries which fall under the 17 ?red? category have installed Continuous Emissions Monitoring System. However, we are lagging behind on certification systems. We still need systems in place to ensure certification of the device, accreditation of labs which manufacture the calibration gases and common data servers at the central level. Also, the policies and legislations must be modified to use data from CEMs for regulatory purposes including legal proceedings.

A few striking changes for thermal power plants which came into force from December 2015

  • New standards for plants that are commissioned after 2016 will cut down emissions of particulate matter by 25 per cent, sulphur dioxide (SO2) by 90 per cent, nitrogen oxide (NOx) by 70 per cent and mercury by 75 per cent, compared to existing state-of-the-art plants, with water use remaining the same.
  • Existing plants will need to meet tighter standards, and will have to ration their water use.
  • Cumulatively, freshwater withdrawal could decrease from around 22 billion cubic metres in 2012 to around 4.5 billion cubic metres in 2017, an 80 per cent dip.

Brief Intro:
Soundaram Ramanthan has been working with the Centre for Science and Environment for over four years as a researcher. She looks into policies related to sustainable industrialisation. She has had the opportunity to work with the coal mining and thermal power plant pollution issues at CSE. She was involved in CSE?s Singrauli mercury pollution study, Green Clearance Watch, which tracks the key sectoral developments including thermal power projects in India since 2007, coastal power research and India?s first environmental rating of coal-based power by CSE (called the "Heat on Power"). She holds a B. Tech degree in Energy and Environmental Engineering from the Tamil Nadu Agricultural University and an M Tech in Energy and Environmental Management from IIT-Delhi.

About CSE
The Centre for Science and Environment (CSE) is a public interest research and advocacy organisation based in New Delhi. CSE researches into, lobbies for and communicates the urgency of development that is both sustainable and equitable. The scenario today demands using knowledge to bring about change. In other words, working India?s democracy. This is what CSE aims to do.

The challenge, as CSE sees, is two-pronged. On the one hand, millions live within a biomass based subsistence economy, at the margins of survival. The environment is their only natural asset. But a degraded environment means stress on land, water and forest resources for survival. It means increasing destitution and poverty. Here, opportunity to bring about change is enormous. CSE calls this knowledge-based activism.

We engineer smarter systems to reduce waste

Published

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’.
