Iron & steel is one of the highest emitting industrial sub-sectors, being responsible for approximately 8% of the global CO2 emissions corresponding to 3 - 3.5 GtCO2eq per annum. Lowering emissions in this sector is a must to reach the targets set in the Paris agreement. Within the coming years, we expect to see the biggest changes in this industry since the industrial revolution.
The role of smart state-of-the-art technology is key in the efficient reduction of emissions. Already today, there are excellent solutions available to cut down the emissions in the metals industry. Metso Outotec’s three proprietary process technologies – Ferrochrome Smelting, Copper Flash Smelting, and Alumina Calcination – are prime examples of solutions that have the capability to make the big difference. Using these leading-edge technologies, our customers in the metals industry reduced their CO2 emissions close to 6 million tonnes in 2020. Almost two thirds of the reduction resulted from ferrochrome smelting, which is the most important alloy in the production of stainless steel – the most used material in the world.
