The key elements of the pHYBi concept are:

Pierrelaye is pHYBi’s Case Study 1 trial site for phytoremediation strategies, located in the north-west of Paris (Île-de-France). Throughout the project, project partners from the Chrono-environnement Laboratory at the University of Louis Pasteur (Montbéliard) will carry out several field monitoring campaigns at this location. These activities form part of work package 1 and help to establish an initial baseline, as well as tracking how the remediation efforts evolve under real site conditions.

The pHYBi project includes several case studies where partners test phytomanagement strategies to address different forms of soil degradation and contamination. One of these sites is located in Belorado near Burgos, displaying high salinity levels caused by active mining operations extracting thenardite and glauberite, minerals used to produce anhydrous sodium sulfate.

On 4 December 2025, the pHYBi project held its first co-creation workshop in Sargentes de la Lora, Spain. Hosted by the University of Burgos and the Digital Innovation Hub on Livestock, Environment, Agriculture & Forest (DIH-LEAF), the event brought together 41 participants from 25 organisations to collaborate on designing a sustainable future for the Ayoluengo oilfield – Spain’s only historic onshore oil extraction site.
