Iron and Steel Industry – Reducing CO2 emissions

To achieve net-zero emissions by 2050, even if total steel production increases, the share of global scrap metal production from electric arc furnaces and combined induction furnaces must exceed 27% by 2030. Now that countries around the world have committed to zero emissions by 2050, sequestering carbon in steel is critical for factories to start reducing their impact on our world. Steel mills are ideal for carbon capture because most of their emissions can be captured directly from process gases and exhaust gases. Various companies are working on this technology, Dastur Energy is one among them. To get more information you can visit

CCS can make a significant contribution to achieving significant reductions in CO 2 emissions in the steel industry. Reducing CO2 emissions from steel mills one of the main options being considered by stakeholders in the steel industry is CO 2 capture and storage (CCS). CO2 capture through demonstration is a mature and proven technology that can be adapted to different industrial sectors.    

For a conventional fossil fuel-fired iron and steel plant, distribution methods have been investigated to determine the CO2 emission intensity of electricity produced by steel mill exhaust as well as to determine the emission intensity of a blast furnace. 

Depending on the operating parameters used, 49.0-83.8% of the total CO2 emissions in a steel plant can be naturally reduced in lime production. All carbon in the process streams captured CO2 and emissions leaving the CAS are attributed to the final steel products in such a way that all direct steel plant CO2 emissions are taken into account.
