On the Cover Improving Sustainable Competitiveness in Preparation for a Circular Economy: The Case of POSCO
In terms of sustainability and a circular economy, steel is not free from environmental concerns, but steel can become a cornerstone for a sustainable circular economy considering lightweighting, long service life, and rich iron ore reserves, Based on whole life cycle, POSCO is applying life cycle assessment (LCA) to develop products from the perspective of sustainable competitiveness and improve their eco-friendliness. Representative products to which LCA was applied include advanced high strength steel (AHSS), Hyper NO electrical sheet, Giga Steel, and PosMAC.
AHSS applied to gasoline vehicles reduces vehicle body weight, improving fuel efficiency and reducing greenhouse gas emissions. Motor cores with Hyper NO minimize core losses, thereby improving the power efficiency of home appliances and cut greenhouse gas emissions. In terms of PosMAC and Giga Steel, POSCO is preparing for a low-carbon circular economy through a full life cycle database and third-party certification. Developing “PosMent” with a higher slag content, POSCO is strengthening the circular industry ecosystem and reduce greenhouse gas emissions.
