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.
Also in 2009 Gusa Nordeste began implementation of its vertical integration project whose conceptual and basic engineering has matured between 2006 and 2009. This project, called AVB Project (Green Steel of Brazil), is the big step of the company to advance steel chain, becoming a producer of long steels.
The project considers the consumption of pig iron produced in the steel cluster of Açailândia for the production of billets and rolled steel (rebar and wire rod), primarily through Gusa Nordeste’s production platform, as well as the production of other companies established in the cluster. AVB Project is the first world steel project genuinely GREEN because its production process does not consume fossil fuels in its chain. In addition, the beginning of its production, which is geared to the domestic market, scheduled for 2016, will lead the company to a decoupling situation from dependence on its revenues from the foreign market and currency fluctuations.
Gusa Nordeste believes that the success and longevity of their future and also of the local productive sector are, definitively, linked to AVB Project.
