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.

The Ramco Cements Limited’s construction chemicals brand, Hard Worker, has won three honours at the Kyoorius Design Awards 2026, including the Grand Prix – Grey Elephant in the Design in Action category.

The brand also secured two Blue Elephant honours, one for Design in Action and another for Packaging, recognising the design approach behind its brand identity and packaging.

Launched in 2025, Hard Worker entered the construction chemicals segment with the brand promise, “Hard-working products for hardworking people.” Its visual identity uses animals and birds to represent product benefits. The camel represents the water-retention capability of Hard Worker Eco Plaster, while the cheetah represents the speed and performance of Hard Worker Block Fix.

The visual language has been extended across packaging, retail, communication, literature, digital platforms and other brand touchpoints. Hard Worker uses bold colours, distinctive animal illustrations and simple visual storytelling to communicate product benefits across markets and audiences, including construction workers and applicators.

“For Hard Worker, design was never an afterthought. It was fundamental to how we wanted to build the brand. In a category that is largely functional, we wanted to create a brand that people could recognise, understand and remember instantly. The Kyoorius recognition is a wonderful validation of this design-led approach,” said Mr. AV Dharmakrishnan, CEO, The Ramco Cements Limited.

Mr. Balaji K. Moorthy, Executive Director – Marketing, Ramco Cements said “In a category where communication has traditionally been product-led and functional, we wanted Hard Worker to stand apart by making design an integral part of the brand experience. From the distinctive animal-led packaging to our communication across consumer and trade touchpoints, every element was designed to make the brand more memorable and the product benefits easier to understand.”

Within its first 12 months, Hard Worker crossed Rs 3.5 bn in sales. The latest recognition follows six honours secured by the brand’s campaign at the Kyoorius Creative Awards earlier in 2026, including the Grey Elephant Grand Prix for its Eco Plaster film.

The Kyoorius Design Awards recognise outstanding design work in India’s visual communications sector across multiple categories and platforms. The 2026 awards were announced on 12 September in Goa.

The Ramco Cements Limited is part of the Ramco Group and operates across cement and allied building-material solutions. Hard Worker is its construction chemicals brand, offering solutions across key construction applications.

Cement Firms to Invest Rs. 130 bn in Green Energy by FY28

Cement companies plan to expand clean energy capacity to 6 GW by FY28

India’s major cement companies are set to raise their clean energy capacity to 6 GW by March 2028 from around 4 GW at the end of March 2026, according to ratings agency ICRA. The planned expansion is expected to involve investments of Rs. 130 bn over the next two years.

The additional capacity could generate annual savings of Rs. 62 bn to Rs. 67 bn, resulting in an estimated payback period of 1.8 to 2.2 years. Cement is an emission-intensive industry, and leading producers have established net-zero roadmaps covering the next 15 to 20 years.

The calcination process accounts for 57 to 60 per cent of the sector’s total emissions, while fuel combustion contributes 27 to 30 per cent and electricity consumption accounts for 10 to 13 per cent. ICRA said the figures highlighted the need for a broad decarbonisation strategy involving green power, blended cement, alternative fuels and improvements in clinker efficiency.

Green energy is considered one of the most commercially attractive decarbonisation options because it can reduce emissions while lowering operating costs. Every 5 per cent increase in green power replacement can reduce power and fuel costs by Rs. 15 to Rs. 16 per tonne. A 25 per cent replacement level could therefore save Rs. 75 to Rs. 80 per tonne and expand operating margins by 140 to 160 basis points.

Cement producers are also assessing carbon capture, utilisation and storage, although high implementation costs, energy requirements and limited transport and storage infrastructure are expected to slow commercial adoption. The government has proposed Rs. 200 bn over five years to support deployment across key sectors. Meanwhile, companies are targeting thermal substitution rates of 10 to 15 per cent over the next three to five years, compared with the current industry level of around 6 per cent.
