Ferrous Industrial Wastes-Valuable Resources for Water and Wastewater Decontamination

Ecaterina Matei et al. Int J Environ Res Public Health. .

Abstract

Ferrous waste by-products from the metallurgical industry have a high potential for valorization in the context of the circular economy, and can be converted to value-added products used in environmental remediation. This research reviews the latest data available in the literature with a focus on: (i) sources from which these types of iron-based wastes originate; (ii) the types of ferrous compounds that result from different industries; (iii) the different methods (with respect to the circular economy) used to convert them into products applied in water and wastewater decontamination; (iv) the harmful effects ferrous wastes can have on the environment and human health; and (v) the future perspectives for these types of waste.

Keywords: TiO2 production; adsorbent; coagulants; ferrous sulfate; ferrous wastes; magnetite; mill scale.
