15th Green Cementech 2019, an annual conference for the cement industry, was organised by the Confederation of Indian Industry (CII) in partnership with the Cement Manufacturers Association (CMA).

The Indian cement industry leads by example in keeping pace with the world’s evolving socio-economic and environmental paradigms, from adoption of new and clean technologies and adhering to stricter environmental standards to making the best utilisation of the waste produced by other industries. This was highlighted by Mahendra Singhi, President, Cement Manufacturers Association (CMA) and Managing Director and CEO, Dalmia Cement (Bharat) Limited.

Singhi was speaking at the 15th Green Cementech 2019, an annual conference for the cement industry organised by the Confederation of Indian Industry (CII) in partnership with the Cement Manufacturers Association (CMA).

Under its Corporate Social Responsibility (CSR) initiatives, the Indian cement industry has adopted more than 700 villages for improving education, healthcare, sanitation, water supply and green cover; created green belts around cement plants through forestry; financed 25 colleges, and established 225 primary and secondary schools, Singhi underlined.

Thanks to its resilience, cement and concrete infrastructure has saved many lives in situations of natural disasters, such as in the recent cyclone Fani in Odisha, Singhi said, adding that it is hence justified to call cement a life-saving material. There is a huge perception gap, with many still thinking about the cement sector as unfriendly to the environment, whereas the reality is that the cement sector is the most energy efficient sector in the country and the world, Singhi underlined, and added that the cement industry stakeholders should come together in reaching out to the public and the government to highlight the significant contribution of the cement sector to India’s Sustainable Development Goals (SDGs).

Singhi also encouraged industry stakeholders to take up more initiatives with State Governments to continue the good work on creating solutions for the betterment of citizens, the industry, and the environment.

Dr BN Mohapatra, Director General, National Council for Cement and Building Materials, underlined the need for more conservation of energy and increased use of clean and renewable energy in the cement industry, as the cement industry is the most energy-intensive industry in the world. Responsible manufacturing of cement, which involves reducing the carbon footprint of the sector, is the need of the hour, Mohapatra said, especially as the cement industry in India is expected to grow by leaps and bound over the next few years. The Indian cement industry has committed to reduce its carbon footprint by 45 per cent by 2050, Mohapatra said, and expressed optimism for the accomplishment of this and related goals Philip Mathew, Chairman, Green Cementech 2019 and Chief Manufacturing Officer, ACC Limited, said that it is important to note that concrete is the second most used compound material in the world, next only to water. Cement is increasingly being seen as unsustainable and an environmental concern, which makes it imperative for the industry to work on green cement technology solutions, Mathew said. More than one million tonnes of coal has been conserved over the years by sustainable cement production practices in the Indian cement industry, Mathew said, and asserted that conservation of non-renewable sources of energy is the only way forward. Cement industry stakeholders must think about future challenges and the opportunities that can arise out of them, such as the inevitable challenge of government restrictions on landfilling of waste and the potential opportunity of recycling humungous piles of waste, Mathew added.

KN Rao, Co-Chairman, Green Cementech 2019, and Director (Energy & Environment), ACC Limited, said that the Indian cement sector is the fuel driving the growth of the Indian economy. Cement is subjected to the highest GST slab, and this is a major impediment to growth, Rao highlighted.

He encouraged the industry stakeholders to work with the government on this and other issues, such as weak financing in the field of energy efficiency and waste management. India has captive power plants with about 55 GW capacity, 60 per cent of which is coal-based, and therefore, there is a huge potential for promoting clean and renewable energy technologies the captive power plants, he added.

Two publications-Cement Formulae Handbook (Ver 3.0) and "Energy Benchmarking for Indian Cement Industry (Ver 4.0)-were released at the inaugural session. For their greening efforts, JK Lakshmi Cement and Orient Cement were awarded GreenPro (Green Product) certification and ACC Bargargh Cement Works was awarded GreenCo (Green Company) Rating.

CII-CMA’s distinguished personality award presented
CII and Cement Manufacturers Association (CMA) in its efforts to appreciate and acknowledge thought leaders and green champions who have contributed significantly to the growth and spread of the cement sector, annually felicitates one senior person with the "CII-CMA Distinguished Personality Award".

CII and CMA had the privilege of felicitating KC Jain, Director, Mangalam Cement at Green Cementech 2019. KC Jain was instrumental in setting up first dry cement plant in the Country at Basant Nagar in 1969.

This pioneering initiative encouraged others to adopt dry process technology at that time.

He was instrumental in setting up Vasavadatta Cement plant, which today is one of the most modern, highly automated and energy efficient plant and has taken several initiatives on sustainability and ecological front.

KC Jain is a strong supporter of incorporating latest technologies, techniques and environmental friendly plants.

Serving as an inspiration to various stakeholders of Indian cement industry, KC Jain has demonstrated how concerted efforts and involvement can enable in making plants energy efficient, cost effective and in the process become world class.

Today as a result of his strategic inputs and thought leadership, Indian cement industry could imbibe some of the best practices in cement industry.

Reclamation of Used Oil for a Greener Future

Published

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’.

Charting the Green Path

Published

The Indian cement industry has reached a critical juncture in its sustainability journey. In a landmark move, the Ministry of Environment, Forest and Climate Change has, for the first time, announced greenhouse gas (GHG) emission intensity reduction targets for 282 entities, including 186 cement plants, under the Carbon Credit Trading Scheme, 2023. These targets, to be enforced starting FY2025-26, are aligned with India’s overarching ambition of achieving net zero emissions by 2070.
Cement manufacturing is intrinsically carbon-intensive, contributing to around 7 per cent of global GHG emissions, or approximately 3.8 billion tonnes annually. In India, the sector is responsible for 6 per cent of total emissions, underscoring its critical role in national climate mitigation strategies. This regulatory push, though long overdue, marks a significant shift towards accountability and structured decarbonisation.
However, the path to a greener cement sector is fraught with challenges—economic viability, regulatory ambiguity, and technical limitations continue to hinder the widespread adoption of sustainable alternatives. A major gap lies in the lack of a clear, India-specific definition for ‘green cement’, which is essential to establish standards and drive industry-wide transformation.
Despite these hurdles, the industry holds immense potential to emerge as a climate champion. Studies estimate that through targeted decarbonisation strategies—ranging from clinker substitution and alternative fuels to carbon capture and innovative product development—the sector could reduce emissions by 400 to 500 million metric tonnes by 2030.
Collaborations between key stakeholders and industry-wide awareness initiatives (such as Earth Day) are already fostering momentum. The responsibility now lies with producers, regulators and technology providers to fast-track innovation and investment.
The time to act is now. A sustainable cement industry is not only possible—it is imperative.
