Summary

The recovery of plastic waste is a key issue towards a circular economy. Through homogeneous catalysis processes involving metal catalysts that are soluble in reducing environments, the aim of this internship is to discover effective catalyst/reducing agent pairs for reducing oxygenated groups and obtaining polyamines from plastic materials.

Full description

INTERNSHIP OBJECTIVES

The internship will focus on the valorization of nitrogen-containing polymers through deoxygenation with the aim of obtaining polyamines compounds with very high potential for the development of new low-carbon resins for Saint Gobain composites (insulation, abrasives, etc.).

The internship programme will be as follows:

  • Development of a catalytic system enabling selective deoxygenation of polymers: synthesis of ligands and catalysts, with particular attention paid to the EHS (Environment, Health, Safety) aspects of the compounds and conditions chosen.
  • Screening of catalytic systems: reactions on simple/model molecules, characterisation of the compounds and identification of the most effective system.
  • Application of the methodology to the model polymer selected from a avariety of ‘N,O) containing resins and characterisation of the products.
  • Preliminary tests on Saint-Gobain composites may be considered depending on the progress of the internship with a view to recycling.
