Ambuja Cements, a leading cement and building material company under the Adani Group, has announced a significant step toward its Net Zero goals. The company has partnered with Finland-based Coolbrook to implement its revolutionary RotoDynamic Heater™ (RDH™) technology. This partnership reflects Ambuja Cements’ commitment to sustainability and innovation in the cement manufacturing process.
Key Highlights of the Partnership
Implementation of RDH Technology
- What is RDH? The RotoDynamic Heater™ (RDH™) uses mechanical energy powered by renewable electricity to generate high temperatures required in cement manufacturing.
- How It Works: The RDH technology replaces fossil fuels in the cement kiln pre-calciner, a critical stage in the cement production process.
- Environmental Impact: This process eliminates carbon emissions from high-temperature heating, a significant contributor to the cement industry’s carbon footprint.
Benefits for Ambuja Cements
- Reduced Fossil Fuel Dependence: Transitioning to RDH technology allows Ambuja to rely more on renewable energy.
- Cost Efficiency: The use of green power not only reduces emissions but also operational costs over time.
- Sustainability Leadership: The partnership reinforces Ambuja’s position as a leader in industrial decarbonisation within the cement sector.
Ambuja Cements’ Net Zero Strategy
Ambuja Cements has consistently demonstrated its commitment to environmental sustainability through innovation and strategic initiatives.
Key Goals for 2028
- Alternative Fuel Replacement (AFR): Increase the use of alternative fuels to 28%.
- Green Power Utilisation: Achieve 60% green power usage in operations.
These initiatives, along with the RDH technology, will significantly contribute to Ambuja’s Net Zero aspirations.
