What are the key benefits of using alternative fuels like RDF in cement kilns?
The adoption of RDF and other alternative fuels offers significant advantages across environmental, economic and social dimensions:

Environmental benefits: Cement kilns using RDF emit fewer greenhouse gases compared to those reliant on fossil fuels like coal or petroleum coke. RDF also helps mitigate the issue of overflowing landfills by diverting waste toward energy recovery.
Economic savings: Alternative fuels are often more cost-effective than traditional energy sources, allowing cement plants to reduce operational expenses.
Sustainability and resource efficiency: RDF facilitates the circular economy by repurposing waste materials into energy, conserving finite natural resources.
Operational flexibility: Cement kilns designed to use RDF can seamlessly switch between different fuel types, enhancing adaptability to market conditions.

What innovations have been introduced in waste-to-energy (W2E) and recycling solutions?
SIDSA’s machinery is meticulously engineered to handle the complex requirements of processing hazardous and bulky waste.

This includes:

Robust construction: Our equipment is designed to manage heavy loads and challenging waste streams, such as industrial debris, tires and large furniture.
Advanced safety features: Intelligent sensors and automated controls ensure safe operation when dealing with potentially harmful materials, such as chemical waste.
Compliance with standards: Machinery is built to adhere to international environmental and safety regulations, guaranteeing reliability under stringent conditions.
Modular design: Allows for customisation and scalability to meet the unique needs of various waste management facilities.

How does your organisation customised solutions help cement plants improve sustainability and efficiency?
We consistently push the boundaries of technology to enhance waste management outcomes.
General innovations and new product development focus on:

Energy-efficient shredders: These machines consume less power while maintaining high throughput, contributing to lower operational costs.
AI-powered sorting systems: Utilise advanced algorithms to automate waste classification, increasing material recovery rates and minimising errors.
Advanced gasification technologies: Convert waste into syngas (a clean energy source) while minimising emissions and residue.
Closed-loop recycling solutions: Enable the extraction and repurposing of materials from waste streams, maximising resource use while reducing environmental impact.

What future trends do you foresee in waste management and alternative fuel usage in the cement sector?
Looking ahead, several trends are likely to shape the future of waste management and alternative fuels in the cement industry:

AI integration: AI-driven technologies will enhance waste sorting and optimise RDF production, enabling greater efficiency.
Bio-based fuels: Increased use of biofuels derived from organic waste as a renewable and low-carbon energy source.
Collaborative approaches: Strengthened partnerships between governments, private industries and technology providers will facilitate large-scale implementation of sustainable practices.
Circular economy expansion: The cement sector will increasingly adopt closed-loop systems, reducing waste and maximising resource reuse.
Regulatory evolution: More stringent environmental laws and incentives for using alternative fuels will accelerate the transition toward sustainable energy solutions.

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.
