RED4SOLS

The RED4SOLS (Electrodialytic remediation technique for heavily polluted soils) project, supported by the Win4Collective program, aims to develop an innovative technology for treating contaminated soils, especially those with high levels of heavy metals, a legacy of Wallonia’s industrial past.

• The approach relies on electrodialytic remediation, using an electrical field to mobilize and extract heavy metals. These contaminants are transported to electrodes through ion-exchange membranes, effectively separating them from the soil.

• The project focuses on scaling up this technique for industrial application, particularly through integration with the soil washing process used by Walloon soil remediation operators.

• During the second steering committee, the CTP (Centre Terre et Pierre asbl) showcased the remediation cell in operation and discussed initial results.

• The project is jointly led by the CTP and the Echanges Eau-Sol-Plantes team from Forest is Life- (Gembloux Agro-Bio Tech, ULiège), with support from the Service public de Wallonie Recherche. Ultimately, the goal is to repurpose these polluted soils, contributing to the valorization of contaminated land.
