BioChip group - Biorefinery: chemistry and eco-processes

The BioChip group

conducts research aimed at deconstructing, purifying, characterizing and adding value to virgin and recycled lignocellulosic plant biomass, as well as optimizing the associated industrial processes. The components obtained (fibers, mono-, oligo- and polysaccharides, lignins, phenolic compounds) are intended for the development of biobased products and materials to meet societal and industrial requirements.

Research areas

Biorefinery

♦ Oxidation processes : delignification and bleaching of lignocellulosic biomass, using green bleaching agents (oxygen, ozone, hydrogen peroxide, enzymes) for the production of cellulose for paper, textile and chemical applications.
♦ Chemical and enzymatic hydrolysis processes of lignocellulosic biomass.
♦ Separation processes (membrane, flottation) and energy efficiency.
 

Characterization of the lignocellulosic biomass constituants

♦ Molecular weight distribution of lignin and polysaccharides.
♦ Functional groups of polysaccharides and lignin.
♦ Lignin-carbohydrates linkages.
 

Bioproducts

♦ Valorisation for chemical products, materials, and bioenergy.
♦ Pure cellulose: development of new processes for the production of cellulose for textile and chemical applications.
♦ Hemicelluloses: development of a sugar platform for the production of biofuels, surface active agents and for medical applications.
♦ Lignin: valorisation in materials or as a source of aromatic compounds.
