What is
Green Steel?
Our green steel is the result of the MGS production route. We start with our green iron in Oman, where HBI is produced through direct reduction. That HBI is then used with scrap in Electric Arc Furnace steelmaking in Thailand to produce lower carbon steel with a practical pathway to further emissions reduction over time.

OVERVIEW
Why Green Steel Matters
Meranti Green Steel is building a practical pathway to lower-carbon steel by combining our green iron, modern EAF-based steelmaking, renewable electricity, and traceable production from the beginning.
Our approach is designed to reduce emissions from day one while improving further over time. It is a step-by-step transition built for industrial performance, commercial resilience, and environmental responsibility.
Lower CO₂ Emissions
Designed for significant emissions reduction compared with conventional blast furnace steelmaking, with further improvement over time.
Future-ready Steelmaking
Built on a greenfield, clean-slate model with no legacy blast furnace constraints.
Renewable Energy Powered
Our process starts with practical lower-carbon inputs today and is designed to improve further as renewable power and green hydrogen scale.
How Our Green Steel Is Made
Our Green Iron
At MGS, our green iron starts in Oman. We produce green HBI through direct reduction, removing oxygen from iron ore to create a high-quality metallic input for steelmaking.
HBI is compressed into dense briquettes, making it safer and more efficient to transport, store, and handle. This gives MGS a stable, lower-carbon iron unit that can move reliably across our value chain.
In Thailand, MGS uses our green HBI together with steel scrap in an Electric Arc Furnace. The steel is then refined, cast, and hot rolled into lower-carbon flat steel products.
The result is our green steel: high-quality, lower-carbon steel designed for customers looking for products with a lower carbon footprint, reliable supply, and greater traceability.
