Sustainable Materials & Environmental Remediation

A recurring part of Fabrice's research is turning waste or low-value streams into functional materials for environmental applications.

Research focus

The featured example synthesizes stabilized iron nanoparticles using acid mine drainage as the iron source and rooibos tea extract as a stabilizing, reducing biological component — then applies the material as a Fenton-like catalyst for dye removal.

The project combines waste valorization, green synthesis, nanomaterials, catalysis, water treatment and circular-economy thinking in a single thread. Related work extends the approach to bimetallic FeMn nanoparticles using the same plant extract.

Impact message Designing environmental solutions in which the feedstock itself can be part of the remediation story.
