Valorification of Ferrous Sludges Resulting from the Steel Industry

Abstract

A particular interest is represented by the unconventional processes of recycling of powdered ferrous waste in order to obtain a product with a high content of metallic iron. The work presents the results obtained from the processing of powdered ferrous waste by briquetting / agglomeration / pelletization as well as the possibility of valorization of the by-products obtained in the steel industry. This study also evaluates the potential of these valorification processes in significantly reducing the ecological footprint of the steel industry, aligning with global environmental sustainability goals and contributing to a greener industrial future. Furthermore, this investigation highlights the role of these processes in fostering a circular economy, where waste is transformed into valuable resources, promoting a sustainable industrial model.
