Shaping a cleaner tomorrow

Tata Steel is committed to responsible growth, pursuing a decarbonisation roadmap to usher in a sustainable future. The Company’s focus on greening the energy mix and implementing nature-based solutions drives its efforts in reducing carbon emissions. Through process improvements, Tata Steel optimises blast furnace fuel rates, increases pulverised coal injection, implements coke dry quenching and utilises waste heat.

Carbon direct avoidance strategies include increasing steel scrap usage, bio-char and hydrogen injection in blast furnaces, and incorporating green electricity with electric arc furnace (EAF). Tata Steel has established a 5 TPD amine CO₂ capture plant from blast furnace gas, running 24/7 for over a year in the Jamshedpur works. The captured CO₂ (with 97% purity in wet basis) is used for reducing the pH of wastewater, and for bottom tuyere injection in LD vessels replacing nitrogen or argon. More such units are planned to be installed in the future.

These initiatives underscore Tata Steel’s commitment to a cleaner tomorrow
