Abstract : The Amazon forest is well known for its wealth of resources. There is a great abundance of iron ore and wood. This situation has promoted the development of pig iron industries based on charcoal for their thermal processes. The current scenario is a pig iron industry that uses charcoal produced in small brick kilns with biomass from sawmill residues. But there are other two potential scenarios that may develop, depending on economical, environmental, technical and political issues. The second is more technologic: charcoal production in big metallic kilns using wood from planted forests. The third is more social: charcoal production in bigger brick kilns using the mixture of wood from forest management residues and sawmill residues. So a Life Cycle Assessment is proposed to verify which scenario is better from an environmental viewpoint. The impact analysis showed that the most important impact categories are Global Warming Potential, Human Toxicity Potential and Terrestrial Ecotoxicity Potential. The second scenario causes less impact, due to sequestration of CO2 during the development of trees and to lower emissions on carbonization. (Résumé d'auteur)
