BioChip - Biorefinery: chemistry and eco-processes

Group leader

Nathalie MARLIN, Associate Professor / HDR*

Research areas


♦ 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.


♦ 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.
