Making process improvements to reduce carbon emissions
Tata Chemicals is boosting sustainability at the Mithapur salt plant by enhancing energy efficiency and cutting carbon emissions. These efforts highlight the company’s commitment to environmental responsibility.
-
Goal
Reduce carbon emissions to achieve neutrality by 2045.
-
Progress
At the Mithapur salt plant, we reduced carbon emissions by about 15MT CO2e annually by improving steam efficiency and fixing leaks in quadruple-effect evaporators. Upgrading a double-effect evaporator to a triple/quadruple effect is projected to cut emissions by an additional 19MT CO2e per year through better energy efficiency.
-
Transitioning to low-emission fuels
Low-emission fuels are critical to the accomplishment of our decarbonisation goals. We have taken several initiatives to steer this transition across our operations.
-
Goal
To scale up biomass procurement in FY 2024-25 to replace ~10% of coal usage.
To establish a dependable supply chain, including energy crop plantation, to ensure consistent access to biomass. -
Progress
Signed an offtake agreement with Vertex Hydrogen, UK, for the supply of over 200 MW of low-carbon hydrogen. In India, we successfully conducted trials for the use of biomass in our current boilers during FY 2023-24.
-
Carbon Capture and Utilisation (CCU)
Tata Chemicals leads efforts to capture carbon emissions and convert them into usable products.
-
Goal
Implement carbon capture across key manufacturing sites.
-
Progress
Successfully implemented Europe’s first CCU plant to capture and convert CO₂ emissions into high-grade products like Sodium Bicarbonate for the pharmaceutical industry.
