  • ECOTOXICITY AND GENOTOXICITY OF STEEL SLAGS:

    The European iron and steel industry produces a considerable amount of waste and by-products. Also in Italy the steel slag production is very high. Steel slags may be reused in recycled materials, such as materials for the construction industry, road base and asphalt mixtures, allowing to reduce the final disposal in a landfill. The reuse of this recycled material may
