19DEC - FEBGREEN TRANSFORMATION RESHAPES THE STEEL INDUSTRY WORLDWIDEDr. Alexander Fleischanderl, Global Head of Innovation & Information Technology, PrimetalsWhy is CO2 emitted during steel production using the LD (BOF) process?Developed in Linz and Donawitz over 70 years ago, the LD process (BOF) is coal-based and accounts for around 70 percent of today's global steel production. However, a good 90 percent of the CO2 is produced in coke plants, sinter plants, and blast furnaces during pig iron production, amounting to 1,770 kilograms of CO2 per ton. A further 170 kilograms of CO2 per ton of steel occur when oxygen is blown into the LD converter and refined into steel.What technical possibilities would the steel industry have today to reduce CO2 emissions?The global steel community agrees that CO2 emissions from existing LD (BOF) steelworks can be reduced by a maximum of around 30 percent through material and energy efficiency measures and other optimization steps, but 90 percent of Primetals Technologies, a pioneer in plant engineering and software production, is developing numerous green steel technologies. Headquartered in the UK, the plant-building company also innovates the digitalization of steel production processes. Dr. Alexander Fleischanderl, Head of Green Steel and Senior Vice President at Primetals Technologies offers his thought-provoking insights on the challenge facing the steel industry to become carbon neutral.Dr. Alexander FleischanderlCXOINSIGHTS
