South Korean steelmaker Posco is preparing to launch a new electric arc furnace (EAF) with a capacity of 2.5 million tons of steel per year at its Gwangyang plant in June.

Why It Matters

This expansion boosts Posco's annual steel output by 2.5M tons, strengthening its market share in a competitive APAC steel market. The EAF technology signifies a strategic shift towards lower-carbon production, enhancing Posco's ESG profile and potentially securing green premiums. It also diversifies raw material sourcing by increasing reliance on scrap, mitigating iron ore price volatility and supply chain risks. This move sets a precedent for regional competitors to accelerate decarbonization efforts.
