For the most part, iron-rich waste streams from several industrial processes are still either dumped or used in low-value building applications. However, these streams contain plenty of valuable metals that can be reclaimed, or residue that can be reused in an innovative way.
Recycling iron-rich waste streams could have a large impact on the entire industrial landscape. In the MaxiVIA-project, financed by the Environment and energy technology Innovation Platform (Milieu- en energietechnologie Innovatie Platform, MIP), VITO and other Flemish partners develop innovative methods for high-quality deployment of these materials. The partners want to reclaim valuable metals using sophisticated separation technologies, but also want to valorise the majority of the material in a suitable manner.
VITO develops valorisation techniques through which iron-rich waste streams can be reused sustainably:
- Pre-treating industrial waste streams through (para-) magnetic separation, in order to reclaim iron-rich fractions.
- Applying hydrometallurgical extraction methods to regain valuable and critical metals (Zn, Pb, Sn and Sb) from waste streams.
- Partner project of four Flemish companies (Antwerp Sand Recycling, Campine Recycling, Daniël Cardinael & Co Comm and Jacobs NV), one civil society organisation (Plan C) and two research institutes (VITO en KU Leuven).
- Duration: February 2015 - January 2017
- Budget: € 800,335, of which MIP contributes € 595,755
