Selective metal separation from steel slags and municipal solid waste incinerator ash (MSWIA) by intensified solvent extraction and precipitation

This project tackles heavy metals removal from two end-of-life streams, notably steel slags (SS) and municipal solid waste (MSW). These slags could be valorized and used in cement and concrete materials after eliminating heavy metals and other toxic components. Intensified cost-effective processes have the potential to be green alternatives for extracting and precipitating heavy metals from steel slags and municipal solid waste incinerated ash (MSWIA), using less or no organic solvents saving time and energy, and improving extraction results over traditional separation methods. This research project focuses on valorizing two types of wastes; steel slags (basic oxygen furnace, BOF, electric arc furnace, EAF and Klockner Oxygen Blown Maxhutte process, KOBM) and MSWIA applying process intensification principles.
