Adani Cement to Deploy World’s First Commercial RDH System

14 Nov 2025 CW Team

Adani Cement and Coolbrook have announced a landmark agreement to install the world’s first commercial RotoDynamic Heater (RDH) system at Adani’s Boyareddypalli Integrated Cement Plant in Andhra Pradesh. The initiative aims to sharply reduce carbon emissions associated with cement production.

This marks the first industrial-scale deployment of Coolbrook’s RDH technology, which will decarbonise the calcination phase — the most fossil fuel-intensive stage of cement manufacturing. The RDH system will generate clean, electrified heat to dry and improve the efficiency of alternative fuels, reducing dependence on conventional fossil sources.

According to Adani, the installation is expected to eliminate around 60,000 tonnes of carbon emissions annually, with the potential to scale up tenfold as the technology is expanded. The system will be powered entirely by renewable energy sourced from Adani Cement’s own portfolio, demonstrating the feasibility of producing industrial heat without emissions and strengthening India’s position as a hub for clean cement technologies.

The partnership also includes a roadmap to deploy RotoDynamic Technology across additional Adani Cement sites, with at least five more projects planned over the next two years. The first-generation RDH will provide hot gases at approximately 1000°C, enabling more efficient use of alternative fuels.

Adani Cement’s wider sustainability strategy targets raising the share of alternative fuels and resources to 30 per cent and increasing green power use to 60 per cent by FY28. The RDH deployment supports the company’s Science Based Targets initiative (SBTi)-validated commitment to achieve net-zero emissions by 2050.
