Abstract: Environmental impact allocation has been noted as one of the life cycle assessment's (LCA) most controversial methodological issues given that it highly influences the study's final result. This paper analyses the appropriateness of available multifunctional modeling methods to distribute environmental loads between pig iron and bfs produced in the steelmaking process, and the influence that modeling choices have on LCA results for different blended cement types commercialized in Brazil.
