India: Adani Cement and Finland-based Coolbrook have announced an agreement to implement the world’s first commercial deployment of Coolbrook’s RotoDynamic heater (RDH) at Adani’s Boyareddypalli integrated cement plant in Andhra Pradesh. The project reportedly aims to ‘significantly’ reduce CO₂ emissions from cement production.
The RDH system will decarbonise the calcination phase of cement production by supplying ‘clean’ heat powered entirely by renewable energy from Adani. The installation is expected to cut around 60,000t/yr of CO₂ emissions, with potential for a tenfold increase in future phases, according to the producer.
The partnership also includes plans to expand the use of RotoDynamic technology across other Adani Cement sites, with five additional projects targeted within two years. The first-generation RDH will deliver hot gases of around 1000°C to dry and optimise the use of alternative fuels.
