Topic description
Ce projet de doctorat mettra en œuvre des procédés d'extrusion réactive pour modifier, fractionner et valoriser des sous-produits agro-industriels, abordant ainsi deux défis majeurs pour l'humanité : l'alimentation et l'environnement. La demande en sources alternatives de protéines ne cesse de croître. Certains sous-produits agro-industriels sont riches en protéines pouvant être utilisées dans l'alimentation, mais il reste à développer un procédé permettant de les extraire efficacement. De plus, le sous-produit restant de cette première extraction, une fraction riche en lignocellulose, doit également être revalorisé pour permettre la valorisation intégrale de cette ressource renouvelable. Bien que les plastiques biosourcés puissent être obtenus à partir de biomolécules raffinées, une approche plus intéressante, mais plus ambitieuse, consiste à les produire à partir de sous-produits agricoles. Ces matériaux ont le potentiel de remplacer les plastiques pétrosourcés, en tant qu'emballages à moindre impact environnemental. Par conséquent, ce projet visera à la fois (1) à développer des procédés d'extrusion réactive pour obtenir des fractions riches en protéines à partir de la biomasse, et (2) à développer des matériaux biosourcés à partir des fractions riches en lignocellulose. Ce projet contribuera ainsi à approfondir les connaissances en ingénierie des procédés appliquées au développement durable.

This PhD project will apply reactive extrusion processes to modify, fractionate and valorise agro-industrial by-products, tackling two main challenges for the humanity: food and environment. The demand for alternative source of proteins is growing. Selected agro-industrial by-products are rich in proteins, which can be applied for food, although the process to efficiently extract them need to be developed. Moreover, the remaining by-product from this first extraction, a lignocellulosic-rich fraction, also needs upcycling for the integral valorisation of the renewable resource. Although bio-based plastics can be obtained from refined biomolecules, a more interesting, but challenging approach, is to produce them from agricultural by-products. These materials have potential to substitute petroleum-based plastics, as packages with lower environmental impact. Therefore, this project will both (1) develop reactive extrusion processes to obtain protein-rich fractions from biomass, and (2) develop bio-based materials with the lignocellulosic-rich fractions. This project, therefore, will contribute to foster the knowledge related to process engineering applied to the sustainable development.
