As plastic waste defines the present era, efforts towards the development of recycling technology are ramping up. For polyolefins (PO), common packaging materials, the available technologies of mechanical recycling and of pyrolysis (thermal conversion) have several drawbacks and can process only a fraction of waste.

Context: Currently, only 10-20% of end-of-life catalysts are recycled after their use in refineries. However, these catalysts contain critical metals (Ni, Co) and the management of these resources is becoming increasingly constrained and regulated. This makes catalyst recycling a major environmental and economic challenge.

IFPEN aims to position itself as a provider of innovative, cleaner, and more efficient processes. The proposed PhD thesis falls within the framework of the implementation and optimization of liquid-liquid extraction for metal recovery in the context of battery recycling.

This PhD position deals with Physics Informed Machine Learning (PIML) modeling methodologies, a novel generation of deep-learning architectures that combines physical laws with data-driven approaches.

Plastic wastes recycling is a major environmental issue. Although European regulations are initiating major changes in terms of collection and incorporation of recycled materials, technologies for recycling such complex streams still must be developed.

With the rise of new technologies and the rapid evolution of transportation modes, understanding mobility behaviors becomes a significant challenge to optimize infrastructure, anticipate transportation demand, and guide public policies.

Per- and polyfluoroalkyl substances (PFAs) represent a family of over 4,000 compounds synthesized since the 1950s, used in various industrial sectors for their exceptional properties (non-stick, waterproof, and heat-resistant).

All solid states Li batteries offer the promise of surpassing the energy density limits of current generations, thanks to the combined use of a solid electrolyte (SE) and a lithium metal anode. The key to this system lies in the choice of electrolyte and its integration into the cell.

The emergence of electric vehicles in the automotive market is increasingly pushing manufacturers to design more efficient and low-cost electric drive chains. These objectives allow to increase autonomy and to be competitive in the automotive market.
