James (Jim) Holden, PE, Technical Director, Energy and Engineered Solutions, and Lisa Marston, Regional Technical Service Engineer, Cortec Corporation, discuss how lubricants play a crucial role in maintaining efficiency, preventing breakdowns and supporting sustainable practices in industrial operations.

What role do lubricants play in the lifespan of any machinery?
Holden: Any manufacturer of rotating equipment will specify the type of bearing and the type of lubricant to be used in their machinery. The main functions of the lubricant are to minimise friction between stationary and moving components and to extend the life of these components by preventing excessive wear and premature failures.

Which are the key areas in any machinery that should be protected by the grease or lubricants?
Holden: Anytime there is relative motion between two pieces of metal, such as bearings and shafts, a lubricant should be used. There are generally three categories of lubricants – lubricating oils, lubricating greases, and general-purpose penetrating lubricants. Each of these has different applications.

Tell us about your products that offer corrosion prevention in machinery. What makes them unique?
Marston: Cortec has products that serve various needs in lubricating systems. One major category of products is oil additives with contact and vapor phase corrosion inhibitors that are designed to provide enhanced corrosion protection in addition to the lubricating oil itself during long term storage and intermittent operating conditions for gearboxes, steam turbines, pumps, etc. Cortec also offers greases that are formulated with vapor phase corrosion inhibitors, some of which are derived from renewable resources. Additionally, Cortec manufactures general purpose lubricants with corrosion inhibitors that can be used on valve bushings, fasteners, and packing glands, as a few examples. The addition of contact and vapor phase corrosion inhibitors in these products ensures consistent corrosion protection throughout the equipment, even when components may not be in direct contact with the lubricant.

How often should lubricants of any kind be changed for effective functionality?
Holden: OEMs and/or lubricant suppliers will recommend operating cycles, how often to inspect the oil, and what tests to run to ensure the oil is healthy for continued operation of their equipment. As part of day-to-day operations, it is also typical to try to minimise the water content in the oils
through purification.

How can sustainability be incorporated in lubrication systems?
Marston: The two major ways that come to mind include:
1. Extending the life cycle of your oil and your equipment to avoid wasted capacity of the assets. This can be done by keeping the oils and systems clean, monitoring the health of the oils over time, and inspecting the equipment on a routine maintenance schedule.
2. Using environmentally friendly corrosion inhibitors and lubricants where possible. Cortec offers several biobased products including EcoLine CLP, a multi-functional penetrant/lubricant made with 89 per cent USDA certified biobased content, and EcoLine Biobased Grease powered by Nano-VpCI which contains 86 per cent biobased content and is formulated from vegetable oils.

What are the advancements made in the field of lubricants that can positively impact productivity of heavy machinery?
Lubricants are indispensable for maintaining smooth machinery operation and preventing costly breakdowns. By reducing friction between moving parts, they minimise wear and tear, extending the lifespan of equipment. Additionally, lubricants absorb shocks, dampen noise, and mitigate corrosion, ensuring optimal performance even in challenging environments. With less friction comes reduced heat generation, further safeguarding against damage and enhancing overall efficiency. In essence, the strategic use of lubricants not only facilitates seamless operation
but also safeguards against unplanned downtime and unexpected expenses. We are looking forward to continued development of biobased and biodegradable alternatives to traditionally petroleum-based products, which are safer for handling and the environment.

Construction Costs Rise 11% in 2024, Driven by Labour Expenses

Cement Prices Decline 15%, But Labour Costs Surge by 25%

The cost of construction in India increased by 11% over the past year, primarily driven by a 25% rise in labour expenses, according to Colliers India. While prices of key materials like cement dropped by 15% and steel saw a marginal 1% decrease, the surge in labour costs stretched construction budgets across sectors.

“Labour, which constitutes over a quarter of construction costs, has seen significant inflation due to the demand for skilled workers and associated training and compliance costs,” said Badal Yagnik, CEO of Colliers India.

The residential segment experienced the sharpest cost escalation due to a growing focus on quality construction and demand for gated communities. Meanwhile, commercial and industrial real estate remained resilient, with 37 million square feet of office space and 22 million square feet of warehousing space completed in the first nine months of 2024.

“Despite rising costs, investments in automation and training are helping developers address manpower challenges and streamline project timelines,” said Vimal Nadar, senior director at Colliers India.

With labour costs continuing to influence overall construction expenses, developers are exploring strategies to optimize operations and mitigate rising costs.

Swiss Steel to Cut 800 Jobs

Job cuts due to weak demand

Swiss Steel has announced plans to cut 800 jobs as part of a restructuring effort, triggered by weak demand in the global steel market. The company, a major player in the European steel industry, cited an ongoing slowdown in demand as the primary reason behind the workforce reduction. These job cuts are expected to impact various departments across its operations, including production and administrative functions.

The steel industry has been facing significant challenges due to reduced demand from key sectors such as construction and automotive manufacturing. Additionally, the broader economic slowdown in Europe, coupled with rising energy costs, has further strained the profitability of steel producers like Swiss Steel. In response to these conditions, the company has decided to streamline its operations to ensure long-term sustainability.

Swiss Steel’s decision to cut jobs is part of a broader trend in the steel industry, where companies are adjusting to volatile market conditions. The move is aimed at reducing operational costs and improving efficiency, but it highlights the continuing pressures faced by the manufacturing sector amid uncertain global economic conditions.

The layoffs are expected to occur across Swiss Steel’s production facilities and corporate offices, as the company focuses on consolidating its workforce. Despite these cuts, Swiss Steel plans to continue its efforts to innovate and adapt to market demands, with an emphasis on high-value, specialty steel products.

UltraTech Cement, the Aditya Birla Group’s flagship company, has announced plans to raise up to Rs 3,000 crore through the private placement of non-convertible debentures (NCDs) in one or more tranches. The move aims to strengthen the company’s financial position amid increasing competition in the cement sector.

UltraTech’s finance committee has approved the issuance of rupee-denominated, unsecured, redeemable, and listed NCDs. The company has experienced strong stock performance, with its share price rising 22% over the past year, boosting its market capitalization to approximately Rs 3.1 lakh crore.

For Q2 FY2025, UltraTech reported a 36% year-on-year (YoY) decline in net profit, dropping to Rs 825 crore, below analyst expectations. Revenue for the quarter also fell 2% YoY to Rs 15,635 crore, and EBITDA margins contracted by 300 basis points. Despite this, the company saw a 3% increase in domestic sales volume, supported by lower energy costs.

In a strategic move, UltraTech invested Rs 3,954 crore for a 32.7% equity stake in India Cements, further solidifying its position in South India. UltraTech holds an 11% market share in the region, while competitor Adani holds 6%. UltraTech also secured $500 million through a sustainability-linked loan, underscoring its focus on sustainable growth driven by infrastructure and housing demand.
