- Type of project: Research
- Event: 2021
The BioExtracT project(Le BIOmimétisme au service de l'EXTRACtion des Terres rares issues de sources secondaires) is an initiative of the Institut ITEM of Aix-Marseille Université, coordinated by Blanche Colin of CEREGE.
This project aims to develop innovative processes for extracting critical metals, in particular rare earths (REEs), from secondary sources such as industrial and mining residues. The approach is based on biomimicry, drawing inspiration from natural biological mechanisms to design extraction methods that are more respectful of the environment.
The main objectives of the BioExtracT project are :
- Identify biological molecules involved in the transfer of rare earths to living organisms.
- Test the complexation potential of these molecules for rare earths, by carrying out selective leaching tests on mining or industrial residues.
In a context of increasing pressure on strategic metal Resources, the production of critical metals from secondary sources is essential to support the development of technologies dependent on these materials, particularly those linked to the ecological transition. The BioExtracT project is therefore part of a circular economy and sustainable development approach, proposing innovative solutions for the recovery of industrial and mining waste.
The project has been selected as part of the ITEM Institute's call for projects in 2021, aimed at promoting interdisciplinary research in favor of environmental transition.
