Lignin is considered as a biowaste of the pulping industry, which is insufficiently exploited in spite of its attractive chemical composition for industrials facing the rarefaction of phenolics coming from the petro-chemical industry. The present project aims at setting the basis for the development of a technology for the production of value-added oligomers and phenolic derivates (monolignols, vanillin and methyl vanillate) from organosolv and hydrolysis lignins, which can be integrated as a "block" of the biorefinery process applied in the valorisation chain of the resource “Wood”.The proposed hybrid technology is a sequential depolymerisation treatment of organosolv and hydrolysis lignins based on acidic chemical oxidation in combination with enzymatic reactions catalyzed by lignin modifying enzymes in order to produce valuable chemicals for an industrial partner (Huntsman Advanced Materials), which can be involved at a later stage in a CTI project with the applicants.The sub-objectives of the project are:1.The further development of a chemical oxidation treatment step with regard to the yield of phenolic products as well as to the nature of the remaining lignin material for a subse-quent enzymatic treatment2.The development of a enzymatic treatment using biocatalytic nanomaterial in a mem-brane reactor, enabling an integrated fractionation of the depolymerisation products and a facilitated recycling of the biocatalysts3.The assessment of the best treatment step sequence for the maximal recovery of valuable compounds
