More particularly, but without limitation, the mechanocatalyt - ic oxidative depolymerization of lignin is performed in non-aqueous/non-solvent a based and solvent-free process, i.e., via a solid- solid mechanocatalytic oxidative reaction methodology. In one particular embodiment, the process of making such oxidative oxid­ ized reaction products includes, without limitation, the step of mechanocatalytically reacting an oxidation catalyst with lignin or a lignin-containing material. The oxidative reaction products obtained from the process include, for example, at least one of vanillin, and syringealdehyde, vanillic acid, and syringic acid.
