Brazil’s Charcoal-Based Pig Iron Gains Export Traction

Planted forests support an established production route

Brazil’s charcoal-based pig iron industry is gaining attention as steelmakers look for commercially available ways to reduce their reliance on metallurgical coal. Minas Gerais, described by SEGS as the world’s largest producer and consumer of charcoal, has developed an industrial chain that combines iron ore with renewable carbon derived from planted forests.

Unlike conventional pig iron made with coke from mineral coal, so-called green pig iron uses charcoal as the reducing agent in the blast furnace. The method is not a pilot technology: Brazilian producers have used it for decades, giving Minas Gerais an established production base while alternatives such as green hydrogen and electrolysis continue to face constraints involving cost, infrastructure and renewable-power availability.

Adriana Maugeri, executive president of the Minas Gerais Forest Industry Association, or AMIF, told SEGS that Brazil’s existing experience is attracting interest from markets seeking practical steel decarbonization options. She said the product combines plant-derived carbon and iron ore in a feedstock that can support lower-emission blast-furnace production.

United States dominates Brazil’s export market

The commercial opportunity is already visible in Brazil’s pig iron trade. According to data from the Minas Gerais iron industry association Sindifer cited by SEGS, Brazil exported 4.06 million tonnes of pig iron in 2025. Exports represented 76.1% of national production, underlining the sector’s heavy dependence on overseas demand.

The United States received 3.37 million tonnes, accounting for about 83% of Brazilian exports. Europe purchased 392,800 tonnes, while shipments to Asia totaled 55,800 tonnes. The concentration gives Brazilian suppliers access to a large established customer base, but it also leaves producers exposed to changes in US demand and trade policy.

For overseas steelmakers and foundries, charcoal-based pig iron offers a way to lower the embedded fossil-carbon content of metallic inputs without waiting for entirely new production systems. For Minas Gerais producers, the potential advantage will depend on their ability to document feedstock origin and emissions performance as customers apply more detailed carbon-accounting requirements.

Aperam demonstrates application in finished steel

The charcoal route extends beyond merchant pig iron. SEGS highlighted Aperam, the largest stainless steel producer in Latin America, as one of the few steelmakers whose steel production is entirely based on charcoal. The same renewable-carbon model is also used in ferroalloy production for applications including electronics, satellites and medical uses.

This existing industrial use is important because it links the forestry chain directly with higher-value metal production. Minas Gerais has around 2.3 million hectares of planted forests, according to AMIF. Those plantations supply several industries, including pulp, charcoal and other bioproducts, and involve large companies as well as small and medium-sized growers.

Forest supply and verification shape growth prospects

Brazilian plantation cycles can be around seven years, supported by the country’s climate, genetic improvement and forest-management technology. Trees capture carbon as they grow and retain part of it in biomass and soil, although the market value of this characteristic depends on credible measurement across forestry, charcoal conversion, transport and metallurgical production.

AMIF estimates that global wood demand could double by 2050. The association argues that expanding renewable plantations on already degraded land could help meet industrial demand while limiting pressure on natural ecosystems. For pig iron exporters, that expansion must remain aligned with traceability and conservation requirements if charcoal is to retain its low-carbon positioning.

Minas Gerais therefore enters the steel transition with an operating supply chain rather than a future concept. Its immediate opportunity lies in supplying importers seeking lower-emission metallic inputs, while its longer-term competitiveness will rest on plantation availability, verifiable carbon performance and diversification beyond a US market that currently absorbs most Brazilian shipments.
