The Skilling Challenge

The skill challenge of cement industry is only a small subset of the larger national objective of achieving demographic dividend that our large youth population can bring us.

Demographics can change the pace and pattern of economic growth and India has one of the youngest populations in an aging world. By 2020, the median age in India will be just 28, compared to 37 in China and the US, 45 in Western Europe, and 49 in Japan. Thus, India is at the threshold of reaping the demographic dividend, while China has already demonstrated its benefits by achieving spectacular growth trends over the last three decades.

However, the growth benefit of a demographic dividend is not automatic. It is a function of the total number of workers and their average productivity. Although the number of workers is growing in India, labour productivity is near stagnant as most of them are employed in the informal sector.

To reap demographic dividend, India must be able to swell its labour force as more people reach working age. But it is not an easy task, given India is home to the world’s largest concentration of illiterate people in the world.

Poor quality of education particularly in science, technology, engineering and mathematics (STEM) without emphasis on the employability of the graduating students is the hindrance. It is also the reason even the biggest companies are facing difficulties in hiring suitably skilled employees.

The situation in the cement industry is no different, so, cement industry’s skill requirements cannot be seen in isolation from that of the country itself.

The challenge There is hue and cry that educated people are not getting employment. On the other hand, the manufacturers complain that they do not get suitably skilled manpower. Thus, there is a serious gap between what is wanted and what is available on ground. Despite Indian cement industry’s immense advancement in energy efficiency, specialised training is essential to overcome certain unique challenges of the Indian cement industry.

‘There is shortage of skilled manpower in the cement industry who can handle such emerging skill sets,’ say Prof. KN Bhattacharjee and Prof. GC Mishra of Department of Cement Technology, AKS University, Satna. (See – Skill in Demand in in-box) The present installed capacity of cement industry is expected to go up from around 435 MT/year to 550 to 600 MT/ annum by 2025. Besides having very low per capita consumption of cement of 225 kg/ annum compared to the global average 500 kg leaves a lot of scope for capacity growth. Given these two factors, AKS University professors say that it is estimated that the cement industry would require around 66,000 skilled technical manpower for greenfield projects, brownfield expansion and captive power plant operations.

Remedy
For addressing the challenge of skill deficit in the country, Bhattacharjee and Mishra suggested designing of training programmes which are completely wedded to the requirement of the construction industry under industry-academia co-operation, enhancing skills of the semi-skilled workers for ensuring better quality and productivity, and making a pool of people ready for the future growth of the cement and construction industry.

Already institutions like National Council for Cement and Building Materials (NCCBM) and AKS University are making considerable contribution in this area by conducting various programmes to train fresh graduates, besides conducting graduation and diploma programmes for the industry. They also regularly conduct short term, customised and contract programmes for improving skills of technical personnel for the industry.

For taking skill development across the country in a mission mode, the Centre has launched the National Skill Development Mission in July 2015 with the aim of creating convergence across sectors and states in terms of skill training activities.

While explaining the quantum of skill challenge, KP Krishnan, Secretary from the Ministry of Skill Development and Entrepreneurship, and Chairman of the National Skill Development Agency (NSDA), said, ‘We want to address the hugely inadequate skill capacity in India; we need ten times the magnitude of what we have today.’ The skill mission has three objectives:

  • increasing the country’s skilling capacity.
  • enhancing quality and employability; and
  • skills acquisition

The backbone of any skilling programme is the formal vocational education and training system, a network of industrial training institutes (ITI). ‘We currently produce something like 16-20 lakh certificate holders per annum: we probably require six or seven times that number. We are increasing ITI capacity massively,’ said Krishnan.

Meanwhile, the skill mission has created a very large ecosystem of short-duration skilling programmes with industry participation, which will partly meet the gap in quality and employability.

As for the aspirational part, typically, if vocational education becomes a dead end and if the child does not have any opportunity to go beyond it, skills will not be aspirational. Likewise, if the skilled employee does not get a higher wage, there is likely to be no aspiration. ‘Our attempt, in a nutshell, is to address both: educational pathways and bringing about a skill-wage premium,’ Krishnan explained.

Another major challenge in the changing dynamics is the firms are offering only contract jobs, even in the areas calling for critical skill sets. ‘In majority of the enterprises in India the contract workers are engaged in noncore and core jobs, paid only the statutory minimum wages or marginally higher, while they continue to serve the enterprise for years, just like permanent employees,’ says Dr Rajen Mehrotra, immediate past president of Industrial Relations Institute of India (IRII), former senior employers’ specialist for South Asian Region with International Labour Organization (ILO).

Looking ahead
Investing in improving the efficiency of people and their skill sets is critical for enabling India to tap into its demographic divided. Thus, failure to address the skill deficit can greatly impact India’s economic future. Besides, it would pose a big challenge for existing and potential investors looking to expand their presence in India and would hinder the success of programmes like Make in India, launched four years back.

To improve the employability of graduating students, educational institutions need to coordinate with corporate entities in designing course curriculum and even sponsoring such courses. New technology should be harnessed to accelerate the pace of building human capital, including through massive open online courses and virtual classrooms.

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.
