The most used and established method for detecting effects of the product on the environment is a method of life cycle assessment (LCA), which analyzes effects of the product on the environment in all five its life stages: design, materials selection, manufacture, use, and ultimately its removal. At the same time LCA is an important tool when we deciding on choosing and optimizing technology and raw materials. In the frame of our study is discussed LCA method as an useful tool in metallurgy, metal production and mechanical engineering praxis. We analyzed potential application of LCA for the Slovenian steel producers and automotive industry, especially the case of ACRONI, the biggest steel producer in Slovenia. Heavy plates of typical steel grades from ACRONI production program were analysed during the first pilot project, and in the frame of the second project a new generation of supercharger housing AUDI EVO was analysed.
