Cement manufacturing is an energy and resource intensive process. We use coal as a primary fuel and electricity powered through the grid. We aim to increase the utilisation of alternative, green and clean sources of energy. Thus, we have taken various targets and commitments.

Targets and Commitments:

As we are gearing up to achieve the target, the requirement of energy will increase drastically and with our commitment for a sustainable growth, it becomes necessary to decrease our coal dependency and increase usage of green energy and alternate fuels as well as implementing waste heat recovery systems across all clinker locations. The benefits of these measures will progressively become evident from FY 2023-24.

• Using alternate fuel: With increased usage of alternate fuels, we observed a rise in our thermal substitution rate (TSR) from 7.1% to 8% last year, owing to increased consumption of industrial waste, plastics/RDF waste, and biomass waste at our Nandyal plant. Our target is to reach 30% by 2030. Our energy sources encompass industrial waste, including pharmaceutical hazardous waste, plastic waste, carbon black, and biomass waste like ground nuts and rice husk.
• Green and Clean Energy: We are progressively increasing our adoption of clean and green power by utilising electricity generated through Waste heat recovery systems (WHRS) and renewable energy accessed through PPAs. In FY 2022-23, around 4% of our power came from clean sources, which will rise to approximately 20% in FY 2023-24.
  • We have installed 12.3 MW WHRS at Nandyal and 9.0 MW at Shiva. The WHRS at Shiva Cement ,meets almost 70% of its energy needs.
  • We currently have secured green power through 15.5 MW solar plant at the Nandyal unit, 8 MW plant at Vijayanagar and 3.5 MW at our Salboni unit, which are helping us decarbonise our carbon footprint.
• Energy efficiency: We take periodic upgrades and initiatives to achieve better energy efficiency in our processes. This helps further in decarbonisation.
