Development of enabling technologies for regional residual biomass valorization in a context of circular economy
Résumé
In the context of a circular economy, the establishment of new waste or coproduct valorisation channels at the scale of a territory requires the development of new technologies and processes leading to innovative solutions. I am working on the residual biomasses available in the Savoie Mont Blanc territory and the Piedmont region to identify new ways of recovering waste or coproducts, common to these two territories (agriculture, agrifood or other local practices). During this presentation, I am presenting the criteria to choose the biowaste(s). The heart of the thesis will focus on the development of new technologies based in particular on unconventional techniques and methods for a green and sustainable process intensification. Among them ultrasound, hydrodynamic cavitation, microwaves, ball milling, extruders, supercritical CO2, and hybrid techniques. The potential applications of extracts are presented.
