Diferenciações na produção siderúrgica e implicações para o desenvolvimento na Amazônia Oriental Brasileira

Strategies for upgrading Amazon designed by the national government had in its proposed guidelines the fragile geopolitical security and regional development, focused centrally for the installation of industrial enterprises, among them the independent steel companies, under the notion that this activity going on would for the production of steel products and so it is to be regional development. By analyzing the differences of production routes independent, integrated and semi-integrated is possible to understand how the elements of industrial plants behave in each route and how they interrelate with the regional socioeconomics. The research work with the pig iron has identified that the independent installation of steel and in the towns of Marabá (PA) and Açailândia (MA) generated unfulfilled expectations of local development, strengthening, therefore, only as an activity that allowed for economic growth, it maintained a production route that articulated the activity with the regional socio-economy in fragile and unsustainable foundations, supported mainly on the demand for charcoal. The cost structures and structural elements of each route identified the differences that each route has, especially in the relationship maintained with the regional economy because it involves new processes, technologies and differentiated products. The logic-based independent production of steel in the transfer and externalization of costs to society, labour relations and limited environmental degradation, without, however, establishing innovation processes led to the failure to establish procedures for the development of local base. The prospect of integrated steel production routes and semi-integrated that settle in the Amazon have no basis to change the scenery and regionally designed to transform the relationships maintained by an independent steel industry in the eastern Amazon, since they interconnect elements that contribute to the consolidation effects backward chaining and forward.

Localização e a construção de estruturas espaciais para a produção e circulação do aço no espaço brasileiro
(Universidade Federal do Pará, 2014-08-18) BARROS, Juan Dias; MONTEIRO, Maurílio de Abreu; http://lattes.cnpq.br/8077335023133373
This work aims to study the question of the location of economic activities, especially on the steel industry in Brazilian space, using the dialectical materialism theory. Thus, attempts to identify the elements both material and thought to provide an understanding of the spatial aspect of the steel production in the context of production of the Brazilian territory. To achieve these objectives, this work made use of survey qualitative data through bibliographic database; and quantitative, using statistical data and location indicators and concentration of economic activities. As a result of analysis, it was found that, unlike the theories based in the idealism and on the formal logic, the location of the Brazilian steel industry is part of the real movement and concrete. This includes historical-spatial process of building for spatial structures aimed at the production and circulation of value in spaces that transformed and incorporated into the dynamics of capital accumulation process. Therefore, the organization of space around the steel industry occurred differently, as seen in the spatial distribution of steel mills, according to the production logic of each space and its relation with the value production processes.

O Mercado de recicláveis do município de Açailândia-Maranhão: análise da economia guseira
(Universidade Federal do Pará, 2005-10-31) COSTA, Janelder Eustaquio Barbosa da; ACEVEDO MARIN, Rosa Elizabeth; http://lattes.cnpq.br/0087693866786684
This study aimed to analyze the steel production economy in the municipality of Açailândia-MA, observing the behavior of economic agents there, in particular for pig iron production with use of charcoal. The investigation resulted from the need to understand the local economic development process as a result of state policies, the Brazilian government adopted in the 1980s The study comes highlight the importance of the Eastern Amazon region to the Brazilian economy, considering their natural resources as commodities necessary for the world economy. This research allowed us to understand the importance of the eastern Amazon to the Brazilian economy.

Siderurgia e carvoejamento na Amazônia: drenagem energético-material e pauperização regional
(Universidade Federal do Pará, 1996-02-27) MONTEIRO, Maurílio de Abreu; BRÜSEKE, Franz Josef; http://lattes.cnpq.br/7311026034758788
This study analyzed the development of the production of merchant pig iron in the Eastern Brazilian Amazon in the last quarter of the 20th century that was intended to supply the international steel market. In the 1980s, the state announced that industrial merchant pig iron plants would be an element in the strategic plan for the economic modernization of the region. This policy justified the granting of tax, credit and infrastructure benefits to 22 merchant pig iron and metallurgy companies. In examining the environmental effects of implementing this plan, the study found that the processes involved in producing pig iron are not energy efficient and have resulted in the consumption of the biomass supply of the Amazonian rainforest without consideration of the ecological consequences, resulting in increased human-generated pressure on that ecosystem. The study found that the plans to cultivate large areas of the rainforest to produce charcoal were not carried out, having been merely rhetoric, with no realistic basis. In the economic dimension, the study indicated that the limited success of the pig iron industry in stimulating processes of modernization is due to, among other things, the fact that the industry’s demand for charcoal is its primary connection with the region’s society and economy. This demand is met by hundreds of suppliers and, in this way, the industry controls the profit margin and reduces its production costs, transferring its private costs to the whole society. In addition, this study showed that the performance of this sector depends on the economic and institutional conditions. Specifically, the planting of forests to provide energy for industry requires long-term investment and there are wide oscillations in the price of pig iron. In addition, there are institutional dynamics at play that make it more possible to illegally exploit primary rainforest biomass for producing charcoal. Historically, these factors have led to the industry using charcoal from primary rainforest biomass rather than that produced through forestry. Based on this evidence, the study concluded that the state’s prediction of a regional modernization trend has not been realized. This is principally due to a lack of ability on the part of society to regulate the processing of materials and energy into merchandise, and the industry has therefore been marked by social and environmental degradation. Its effects have been contrary to those predicted in the state’s rhetoric; it has accelerated the transfer of energy, materials and value to other regions. The region has not had the capacity to balance this loss of energy and material resources with the importation of products, nor has the loss been balanced by the implementation of efficient mechanisms for the ndustrialization of the region.
