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.

Nuvoco Vistas Corp. Ltd reported a strong financial performance for the quarter ended 31 December 2025 (Q3 FY26), driven by record cement sales, higher premium product volumes and improved operational efficiencies.

The company achieved its highest-ever third-quarter consolidated cement sales volume of 5 million tonnes, registering growth of 7 per cent year-on-year. Consolidated revenue from operations rose 12 per cent to Rs 27.01 billion during the quarter. EBITDA increased sharply by 50 per cent YoY to Rs 3.86 billion, supported by improved pricing and cost management.

Premium products continued to be a key growth driver, sustaining a historic high contribution of 44 per cent for the second consecutive quarter. The strong momentum reflects rising brand traction for the Nuvoco Concreto and Nuvoco Duraguard ranges, which are increasingly recognised as trusted choices in building materials.

In the ready-mix concrete segment, Nuvoco witnessed healthy demand traction across its Concreto product portfolio. The company launched Concreto Tri Shield, a specialised offering delivering three-layer durability and a 50 per cent increase in structural lifespan. In the modern building materials category, the firm introduced Nuvoco Zero M Unnati App, a digital loyalty platform aimed at improving influencer engagement, transparency and channel growth.

Despite heavy rainfall affecting parts of the quarter, the company maintained improved performance supported by strong premiumisation and operational discipline. Capacity expansion projects in the East, along with ongoing execution at the Vadraj Cement facilities, remain on track. The operationalisation of the clinker unit and grinding capacity, planned in phases starting Q3 FY27, is expected to lift total cement capacity to around 35 million tonnes per annum, reinforcing Nuvoco’s position as India’s fifth-largest cement group.

Commenting on the results, Managing Director Mr Jayakumar Krishnaswamy said Q3 marked strong recovery and momentum despite economic challenges. He highlighted double-digit volume growth, premium-led expansion and a 50 per cent rise in EBITDA. The company also recorded its lowest blended fuel cost in 17 quarters at Rs 1.41 per Mcal. Refurbishment and project execution at the Vadraj Cement Plant are progressing steadily, which, along with strategic capacity additions and cost efficiencies, is expected to strengthen Nuvoco’s long-term competitive advantage.

Cement Industry Backs Co-Processing to Tackle Global Waste

Industry bodies recently urged policy support for cement co-processing as waste solution

Leading industry bodies, including the Global Cement and Concrete Association (GCCA), European Composites Industry Association, International Solid Waste Association – Africa, Mission Possible Partnership and the Global Waste-to-Energy Research and Technology Council, have issued a joint statement highlighting the cement industry’s potential role in addressing the growing global challenge of non-recyclable and non-reusable waste. The organisations have called for stronger policy support to unlock the full potential of cement industry co-processing as a safe, effective and sustainable waste management solution.

Co-processing enables both energy recovery and material recycling by using suitable waste to replace fossil fuels in cement kilns, while simultaneously recycling residual ash into the cement itself. This integrated approach delivers a zero-waste solution, reduces landfill dependence and complements conventional recycling by addressing waste streams that cannot be recycled or are contaminated.

Already recognised across regions including Europe, India, Latin America and North America, co-processing operates under strict regulatory and technical frameworks to ensure high standards of safety, emissions control and transparency.

Commenting on the initiative, Thomas Guillot, Chief Executive of the GCCA, said co-processing offers a circular, community-friendly waste solution but requires effective regulatory frameworks and supportive public policy to scale further. He noted that while some cement kilns already substitute over 90 per cent of their fuel with waste, many regions still lack established practices.

The joint statement urges governments and institutions to formally recognise co-processing within waste policy frameworks, support waste collection and pre-treatment, streamline permitting, count recycled material towards national recycling targets, and provide fiscal incentives that reflect environmental benefits. It also calls for stronger public–private partnerships and international knowledge sharing.

With global waste generation estimated at over 11 billion tonnes annually and uncontrolled municipal waste projected to rise sharply by 2050, the signatories believe co-processing represents a practical and scalable response. With appropriate policy backing, it can help divert waste from landfills, reduce fossil fuel use in cement manufacturing and transform waste into a valuable societal resource.
