Past few years cement companies have been aggressively targeting at reducing energy consumption. How do you look at this trend? Please explain which cooling technique is energy efficient and why?
The resistivity of cement dust reduces with lower gas temperature. There is always a debate between air dilution and gas cooling with water. Dilution with air entails bigger size downstream equipment like a fan, motor, bag house size, etc. The efficiency of gas cooling with water is fifteen times more efficient than cooling with dilution air. Hence, air dilution is a drain on energy consumption and proper water spray technological solution is required and available, for reducing the gas temperature and thereby its volume.

Most industries today use gas filtration techniques to reduce dust from cement, lime, steel, and other plants. Kindly throw some light on the latest gas filtration techniques for the cement industry.
India has done quite well in addressing the process of dust emissions from the industries, as mandated by the legislature. However, the fugitive dust levels are alarmingly high. The PM2.5 and PM 10 levels are quite high compared to the legislative values, which are affecting human health and well-being. Our technology of producing the required droplet size to encapsulate the dust particle and making it heavy to settle down is our main know-how.

Gas conditioning towers (GCT) are being used in the cement plants to cool down hot gases from kilns. But due to less space in plants, do you see it as a challenge? I
n most modern plants, the GCT is getting phased out due to space constraints. However, the required gas cooling is being done in the Preheater downcomer duct or top cyclone. We have excellent water spray technology for PH downcomer and for TOP cyclone of cement plants.

What are the trends in the cement industry when it comes to selecting the best gas cooling product. Cost is one of the biggest factors. What are the other factors?
Gas cooling by an efficient water spray system is the most efficient cooling method by the laws of physics. Lesser the gas temperature, the gas volumes to be handled are lower, thereby lowering the size of downstream equipment, energy requirements, and the cost of production. Hence, wherever air dilution is taking place in a cement plant, we should look at installing efficient water spray systems. Nowadays, we have spray technology that can handle rejecting water/waste water from cement processes for gas cooling.

How was the demand in the year 2020? Was your business affected too? What were your strategies to survive and compete in the market?
Air Pollution has no holiday. So, our products were in demand and we did manage to grow a bit in 2020. The pandemic made it difficult to offer our services at the customer?? place, which has been our SOP.

Our strategy is to offer tailor-made solutions to our customers??requirements. We have a fluid mechanics laboratory in which the dust characteristics are studied, before the selection of our technology for the best and sustainable results.

How do you foresee business in the year 2021-22? Do you have any strategies for the third wave, if it may hit us soon?
It is the set direction of our sails, which determines the way we want to go. The wind direction does not determine our destination. The pandemic situation may come and go, but we believe in our long term strategy to innovate, focus on customer?? requirements, be agile, adapt to new business norms and be profitable. We have handled the last two waves successfully and are confident about the future business prospects.

Which of your products do you see will be the most popular selling products for the cement market? Why?
Our entire product line for gas cooling, fugitive dust control, odour control, cooling and humidification, mill injection systems. Our product lines are for specific applications which will improve the quality and productivity of our customers??processes.

Cement players are adopting the latest technologies to achieve plant efficiency and cost reduction. Kindly share your views.
Yes, the Indian cement industry is technologically superior compared to many other developed countries. Most of our plants are of capacities over 3000 TPD dry kiln process with 6 stage preheater towers. The latest plant capacities are in the region of 10,000 TPD with 7 stage preheater towers. The energy efficiency is comparable to the best in the business. The specific electrical consumption is also very low compared to the world average.

Kindly share your future roadmap/investments.
We are upbeat about our future plans. We will be expanding our product portfolio as soon as the pandemic is coming to an end. We are also looking to increase our production capacities mainly for export to European countries. We have a goal to double our sales by 2025.

Cement Margins to Erode as Energy Costs Rise: CRISIL

CRISIL warns of 150–200 bps margin decline this fiscal

Crisil Intelligence (CRISIL) released a report on April 13, 2026, indicating Indian cement manufacturers face margin erosion of 150–200 basis points this fiscal, reducing operating margins to between 16 per cent and 18 per cent. The firm noted that this represents a reversal from the prior year when margins expanded by 260–280 basis points. The analysis attributed the shift to rising input costs despite steady demand.

The report said that power and fuel, which typically account for about 26–28 per cent of production cost, are expected to increase by 10–12 per cent year on year, driven by higher prices for crude oil, petroleum coke and thermal coal. Brent crude was assessed as likely to trade between $82 and $87 per barrel, and industrial diesel prices rose by 25 per cent in March, raising logistics and procurement expenses. Such increases have therefore heightened cost pressures across the value chain.

Producers plan to raise selling prices by one–three per cent, which would put the average retail price of a cement bag at around Rs355–Rs360, according to the report. CRISIL’s director Sehul Bhatt was cited as saying that these hikes will at best offset a four–six per cent rise in production costs, leaving little room for higher profitability. The report added that intense competition and continual capacity additions constrain the extent to which firms can pass on costs.

Demand conditions remain supportive, with CRISIL projecting volume growth of six point five–seven point five per cent this fiscal on the back of accelerated infrastructure projects and steady industrial and commercial consumption. Nonetheless, the pace of recovery is sensitive to developments in West Asia, the speed of government infrastructure execution and monsoon performance. The agency noted that any further escalation in energy prices or delays in project execution would widen margin pressures.

Overall, the sector will continue to grow but with compressed margins as energy cost inflation outpaces the limited ability to raise prices. Investors and policymakers will therefore monitor both input cost trajectories and policy measures aimed at alleviating supply chain constraints.

Siyaram Recycling Industries Limited (Siyaram Recycling) has informed the stock exchange that it has secured a purchase order for brass scrap honey from Anurag Impex. The company submitted the intimation on 10 April 2026 from Jamnagar and requested the filing be taken on record. The filing was made under the provisions of regulation 30 of the SEBI listing regulations and accompanying circular. The intimation referenced the SEBI circular dated 13 July 2023 and included an annexure detailing the terms.

The order carries a fixed cost value of Rs 21.03 million (mn) and is to be executed domestically within seven days. The contract was described as a fixed cost engagement and the customer was identified as Anurag Impex. The announcement specified that the order size contributes a short term consideration to the company. Owing to the brief execution window, logistics and dispatch were expected to be prioritised.

The filing clarified that neither the promoter group nor group companies have any interest in the purchaser and that the transaction does not constitute a related party transaction. Details were provided in an annexure and the document was signed by the managing director, Bhavesh Ramgopal Maheshwari. The company referenced compliance with SEBI disclosure requirements in its notification. The notice indicated that no related party approvals were required owing to the nature of the transaction.

The order is expected to provide a modest near term revenue inflow and to be processed within the stated execution window given the nature of the product and the fixed cost terms. Management indicated the contract will be executed in accordance with standard operational procedures and accounting recognition at completion. The development signals continuing demand in the secondary metals market for brass scrap.
