In 1990, Ferroeste Group began to implement in Açailândia (MA), a plant with capacity to produce 125,000 tons of pig iron per year. In 1993, the operations of Gusa Nordeste had started with the objective to take advantage of the great potential of the Carajás ore and its logistics, as well as the privileged conditions of the port in São Luis.
In 1997, aiming to increase the production, Gusa Nordeste built the second Blast Furnace, raising the production capacity to 255,000 tons per year. In 2005, the third Blast Furnace was built, raising the production capacity to 360,000 tons per year. Much of this production is exported to North American companies.
Over the years, Gusa Nordeste, committed to the environment, has been using all the waste generated at the plant. In 2006, the company acquired a plant of pulverized coal injection, taking advantage of all the fines created on the sieving of charcoal and consequently reducing the consumption of granular charcoal made in the furnace via top. In 2008, aiming to use the blast furnace gas generated in the manufacturing process of pig iron, Gusa Nordeste implemented a plant for generation of electric energy. The thermoelectric power plant generates twice the energy consumed by the plant through a boiler fueled by blast furnace gas. This gas feeds the plant boiler, where it is completely burned indoors, producing low cost energy and reducing waste gas generated in the production of pig iron. With the acquisition of the Thermoelectric Central, Gusa Nordeste became self-sufficient in electric energy. In 2009, in order to reuse another waste generated at the plant, Gusa Nordeste acquired a plant for slag grinding, what allowed the processing of 100% of the slag generated in the blast furnace, making it a applicable product in the manufacture of cement, and fertilizers.
Gusa Nordeste also participates in the Fundo Florestal Carajás, administered by Asibras. In the Fundo Florestal, Gusa Nordeste fulfills its forest plans with systematic plantings of approximately 5,000 hectares per year in the state of Maranhão. The planting’s purpose is to support the company´s self-sustainability with charcoal from its own planted forests (eucalyptus). In 2009, Gusa Nordeste reached self-sufficiency in charcoal with eucalyptus plantation in sufficient area to support the fullness of the company’s demand for charcoal.
