The Indian cement industry scaled up WHRS additions by 4x during FY13-20 to 652MW and another 40% addition by FY23 is underway. This helps the Indian cement industry to sustain its global leadership on energy efficiency and to lower its carbon footprint while boosting op margins. Companies in the north-central region are the major gainers as most of them have ~15% of the In this thematic, we analyse the Indian cement industrys environment friendly and structural cost reduction effort Waste Heat Recovery System (WHRS). A WHRS part recycles kilns exhaust heat to generate electricity at negligible op cost (hence attractive payback). This reduces fossil fuel consumption intensity and thus CO2 emissions! ir electricity needs being met through WHRS.
