Gaurav Mathur, Director and Chief Executive, Global Technical Services, discusses the importance of an on-site oil testing laboratory within industrial plants for improved safety, extended equipment life and cost effectiveness in the manufacturing sector.

Oil condition monitoring can provide important information about the condition of the machine through oil analysis. Lubricant in any machine is like blood in the human body. Just as a blood test can help a doctor diagnose an illness and inform a treatment plan, similarly an oil analysis can provide an effective way to know the machine condition and inform it to take maintenance decisions.
Once the oil test laboratory is within the plant, the test reports are made available to the machine maintenance team within a timeline of 48 hours. Timely action helps reduce the expensive mechanical maintenance costs and improves machine life and productivity, leading to the plant’s profitability.
Normally, the oil testing laboratories are far away from the plant. They are mostly in a different city, and these laboratories provide test reports after 10 to 15 days. However, those reports are of no use in machine maintenance as mechanical damage starts to set in within 48 hours in any machine. Hence, it is important to have an on-site oil test laboratory within the plant.
Oil condition monitoring, covering moisture (water presence in the oil), particle contamination, wear debris analysis or loss of additives level, etc. are the parameters that clearly bring out any machine’s internal condition. This reporting leads to timely maintenance decisions by the mechanical team. These reports also help improve the reliability of the machine being tested.
Thus, an oil testing laboratory within the plant site is instrumental in greatly improving the value of machine life and reducing a major cost of mechanical maintenance. These improvements and cost reductions in turn lead to cost savings, profitability and enhance efficiency in manufacturing.

OIL ANALYSIS AT SITE LABORATORY
Oil analysis is an important activity used to check oil health, oil contamination, oil cleanliness level, and machine wear. Its main purpose is to verify that a lubricant in the machine is operating with the oil in good condition i.e. the oil is free from any contamination due to continued usage in the machine over a period of time.
An on-site oil testing laboratory helps to form a system for early detection of oil degradation, contamination, and machine wear. Early detection has several benefits that ensure a healthier environment for the employees and the machinery, such as improved safety, early detection and warning of machine degradation, and increased equipment availability and effectiveness.
Once the oil testing laboratory is established within the plant, thereafter, the next step is to prepare department-wise, machine-wise oil testing schedules. These schedules ensure that there is periodic oil testing and subsequent corrective measures can be taken by the mechanical team. This kind of reporting and availability of the
on-site laboratory leads to a more proactive mechanical maintenance.
Almost 82 per cent of wear-related failures are the direct result of particle contamination.
It is a well-known fact that lubricating oils in a machine never dies. Once the contaminants are removed and the oil cleaned to its original level, the oil can be made as good as ‘new’. Hence, a good oil filtration and accurate additives treatment at site assumes considerable importance in ‘oil conservation’ in the industry. By conducting the above activity about 40 per cent to 50 per cent conservation of the lubricant oil can be achieved.
Hence, having a site condition monitoring laboratory not only improves the life of the machines, it also reduces mechanical maintenance costs and can bring a large economic change in the cement manufacturing sector. Besides, oil can also be recycled to its original level. Thus, having an on-site oil testing laboratory is paramount important and profitable for all large industries.

Nuvoco Vistas Corp. Ltd., one of India’s leading building materials companies, has reported its highest-ever second-quarter consolidated EBITDA of Rs 3.71 billion for Q2 FY26, reflecting an 8% year-on-year revenue growth to Rs 24.58 billion. Cement sales volume stood at 4.3 MMT during the quarter, driven by robust demand and a rising share of premium products, which reached an all-time high of 44%.

The company continued its deleveraging journey, reducing like-to-like net debt by Rs 10.09 billion year-on-year to Rs 34.92 billion. Commenting on the performance, Jayakumar Krishnaswamy, Managing Director, said, “Despite macro headwinds, disciplined execution and focus on premiumisation helped us achieve record performance. We remain confident in our structural growth trajectory.”

Nuvoco’s capacity expansion plans remain on track, with refurbishment of the Vadraj Cement facility progressing towards operationalisation by Q3 FY27. In addition, the company’s 4 MTPA phased expansion in eastern India, expected between December 2025 and March 2027, will raise its total cement capacity to 35 MTPA by FY27.

Reinforcing its sustainability credentials, Nuvoco continues to lead the sector with one of the lowest carbon emission intensities at 453.8 kg CO? per tonne of cementitious material.

Jindal Stainless Limited has announced an investment of $150 million to build and operate a new wet milling plant in Jajpur, Odisha, aimed at doubling its capacity to recover metal from industrial waste. The project is being developed in partnership with Harsco Environmental under a 15-year agreement.

The facility will enable the recovery of valuable metals from slag and other waste materials, significantly improving resource efficiency and reducing environmental impact. The initiative aligns with Jindal Stainless’s sustainability roadmap, which focuses on circular economy practices and low-carbon operations.

In financial year 2025, the company reduced its carbon footprint by about 14 per cent through key decarbonisation initiatives, including commissioning India’s first green hydrogen plant for stainless steel production and setting up the country’s largest captive solar energy plant within a single industrial campus in Odisha.

Shares of Jindal Stainless rose 1.8 per cent to Rs 789.4 per share following the announcement, extending a 5 per cent gain over the past month.

Vedanta gets CCI Approval for Rs 17,000 MnJaiprakash buyout

Acquisition marks Vedanta’s expansion into cement, real estate, and infra

Vedanta Limited has received approval from the Competition Commission of India (CCI) to acquire Jaiprakash Associates Limited (JAL) for approximately Rs 17,000 million under the Insolvency and Bankruptcy Code (IBC) process. The move marks Vedanta’s strategic expansion beyond its core mining and metals portfolio into cement, real estate, and infrastructure sectors.

Once the flagship of the Jaypee Group, JAL has faced severe financial distress with creditors’ claims exceeding Rs 59,000 million. Vedanta emerged as the preferred bidder in a competitive auction, outbidding the Adani Group with an overall offer of Rs 17,000 million, equivalent to Rs 12,505 million in net present value terms. The payment structure involves an upfront settlement of around Rs 3,800 million, followed by annual instalments of Rs 2,500–3,000 million over five years.

The National Asset Reconstruction Company Limited (NARCL), which acquired the group’s stressed loans from a State Bank of India-led consortium, now leads the creditor committee. Lenders are expected to take a haircut of around 71 per cent based on Vedanta’s offer. Despite approvals for other bidders, Vedanta’s proposal stood out as the most viable resolution plan, paving the way for the company’s diversification into new business verticals.
