The environmental management of steel mill slag should be understood as a management philosophy, observing technical, economic and environmental criteria associated with their generation, storage and final destination The slag can be considered as a synthetic mineral resource and become a very useful co-product in different areas. The Argentinean steel industry prioritizes the efficient environmental management of its waste, thus contributing to its own survival taking into account the sustainable development. In the world, the slag produced by the steel industry has been used as steel aggregate for road bases, railway ballast and filling material among others. Any factor that influences the economy of the country affects all branches of society, mainly public agencies, whose financial resources are increasingly scarce to deal with all public works. It is necessary to join efforts of private and public initiative in the adoption of alternative materials that replace the use of finite natural resources. This presentation aims to show the work done by private companies together with public bodies and universities to obtain a regulatory document for the management of slag as steel aggregates for three different uses, namely: road use, railway use and general use.
