Enhancing energy efficiency
Through continuous monitoring and maintenance of equipment and machineries, Prism Johnson strives towards attaining better energy efficiency across all business divisions.
Use of Renewable Energy:
Prism Johnson is committed to increasing the share of renewable energy in its energy mix. Prism Cement has an installed capacity of 22.5 MW of solar power and 22.4 MW of Waste Heat Recovery System (WHRS). In 2021-22, 36.6% of Prism Cement’s total power consumption was sourced from WHRS and other renewable sources (solar and biomass). Further, Prism Cement aims to increase its share of power from renewable sources (including WHRS) to over 50% of total power consumption by 2024-25. Additionally, HRJ has a total installed capacity of 4.5 MW solar energy across its plants.
Prism Johnson’s objective is to optimise withdrawal of groundwater to ensure that it does not adversely impact groundwater levels. Further the Company looks to recharge ground water levels through the rainwater harvesting structures that have been constructed across plants.
Reduction of Clinker Factor and use of alternative materials:
Replacement of clinker in cement by low carbon alternatives is one of the primary decarbonisation strategies of the Company. Prism Cement and Prism RMC use fly ash, ground blast furnace slag (GGBS), copper slag etc. as alternate materials. During 2021-22, Prism Cement used 16%, Prism RMC used 4% and HR used 9% alternative raw materials.
The Company aims to reduce the carbon intensity of its production process by substituting conventional fossil fuels with alternate fuels. Prism Cement uses RDF (Refuse Derived Fuel) in its kilns and has aims to increase the Thermal Substitution Rate (TSR). Additionally, HRJ has been making use of cashew husk and resin waste as a replacement for fossil fuels.
Carbon Sequestration and Carbon Capture and Storage (CSC):
As a part of the Company’s decarbonisation agenda, it aims to explore different CCS technologies. Prism Johnson’s ambition is to experiment with different technologies and reach cost-effective solutions.
