Abstract
A method for depolymerization of lignin includes oxidizing non-phenolic lignin by putting into presence, in at least one solvent, non-phenolic lignin, laccase, redox mediator and a source of oxygen, whereby a mixture including oxidized non-phenolic lignin is obtained, and further includes depolymerization of the oxidized non-phenolic lignin thereby obtained, by adding an oxidizer. The non-phenolic lignin is obtained from phenolic lignin by functionalization of phenol functions of the phenolic lignin.
