The second stage of our BIORECOVER project consists of the pre-treatment of the raw materials to facilitate their treatment. This pre-treatment stage aims at increasing the concentration and accessibility of the CRMs present in the raw material sources by removing interfering components. To do so, our team is experimenting the use of biocatalysts such as the microbial action of fungi or of indigenous bacteria. After testing different biocatalysts on all targeted raw materials, the most efficient pre-treatment process will be validated for each targeted raw material.
“What components are removed at this stage?“
- Iron (Fe), Aluminium (Al), Calcium (Ca) and Titanium (Ti) for BR
- Silicon (Si), Iron (Fe) and CaCO3 for MgW
- Cupper (Cu), Nickel (Ni) and Cobalt (Co) for PLGO
- Cupper (Cu), Nickel (Ni), Zinc (Zn) and Iron (Fe) for PCBP
