Description du projet
La biorécupération de matières premières essentielles
L’Europe dépend presque entièrement des importations provenant de la Chine, de l’Afrique du Sud et de la Russie en matière de terres rares, de magnésium et de métaux du groupe du platine. Le projet BIORECOVER, financé par l’UE, développera un processus sûr et durable fondé sur la biotechnologie pour extraire de manière sélective un éventail de matières premières essentielles issues de sources primaires et secondaires inexplorées. Le processus reposera sur l’intégration de trois étapes principales pour atteindre les valeurs prévues pour le taux de récupération (90 %), la sélectivité (95 %) et la pureté (99 %): l’élimination d’impuretés métalliques, la mobilisation des métaux via des micro-organismes et la récupération des métaux. Pour atteindre ses objectifs, le projet a créé un consortium pluridisciplinaire couvrant l’ensemble de la chaîne de valeur dans sept pays différents.
Objectif
The objective of BIORECOVER is the R&D of a new sustainable & safe process, essentially based on biotechnology, for selective extraction of a range of Critical Raw Materials, from relevant unexploited secondary & primary sources:
-Rare Earths from Bauxite Residue from Greece (MYTILINEOS)
-Magnesium from Mg wastes of low grade minerals and calcination by-products- from Spain (MAGNA)
-Platinum Group Metals from flotation tailings from South Africa (UWITS) & PGM slags, dusts and press cake from United Kingdom (JM)
To this end, BIORECOVER will be based on the integration of 3 main stages to reach the expected recovery rates (90%), selectivity (95%) & purity (99%) (TRL from 2-3 to 5):
(1) Remove the major impurities presents in raw materials sources to achieve the greater availability of the target metals for their recovery.
(2) Mobilise these metals through specific and improved microorganisms to get a leachate enriched with the target CRMs.
(3) Development of a specific technology for recovering metals with high selectivity & purity that meet the quality requirements for its reuse.
Downstream processes will be also studied of the recovered metals for their reuse (brakes pads, oxygen sensors, powder Mg & catalysts). The different stages of the process provide it modular capacity increasing its adaptation flexibility and thus, further market penetration.
LCA & LCC and a Decision Making Framework will support these aims. The awareness, trust & acceptance of the society about the importance of raw materials will be addressed by an awareness campaign and public perception studies. The project results will contribute to EU bio-mining knowledge (RMIS) and a communication with other key project will be also set up.
To achieve this ambitious project, a multidisciplinary consortium covering the whole value chain (from suppliers to end users) will be involved, being represented 7 member states across EU (ES, DK, FR, LE, PT, SE & UK) and effective international cooperation with ZA
