Ambuja Cements had recently announced the successful completion of sea trials using soya extract-based biofuel in two captive cement carriers, Ambuja Mukund and Ambuja Vaibhav, making it not just the first Indian company to move towards the decarbonisation of the country's coastal shipping lines but also advancing its focus on two of its strategic priorities — innovation and sustainability. Ambuja Cement and ACC are also investing ₹780 crore in setting up six Waste Heat Recovery Systems (WHRS) of 76 MW at eight kiln lines across six cement plants. The WHRS is expected to reduce the carbon footprint by 5.61 lakh tonnes annually. In addition to boosting efficiency, the proposed investments in WHRS will help LafargeHolcim plans to reduce emissions. Ambuja and ACC have relatively low carbon dioxide emissions of 531 kg and 493 kg CO2 per tonne of cementitious material respectively.
