NOVELTY - Biorefining lignin biomass (8) comprises providing lignin biomass, processing the lignin biomass, and producing at least one product from the lignin biomass.    USE - The method is useful for biorefining lignin biomass to produce at least one product including biobased aromatic chemicals, biobased aromatic fuels and lignin residues, where the biobased aromatic chemicals and the biobased aromatic fuels are at least one chemical of commodity chemicals, fine chemicals, and specialty chemicals, preferably aromatic carboxylic acids, aromatic esters, aromatic aldehydes, aryl ketones, aryl alcohols, aryl ethanes, aryl ethenes, aryl ethynes, aryl propanes, aryl propenes, aryl propynes, cresols, phenols, benzenes, pyrolytic oils, methyl and ethyl 4-hydroxybenzoate, methyl and ethyl vanillate, methyl and ethyl syringate, 4-hydroxybenzoic acid, (4-hydroxyphenyl)acetic acid, vanillic acid, homovanillic acid, syringic acid, homosyringic acid, 4-hydroxybenzaldehyde, vanillin, syringaldehyde, 4-hydroxybenzyl alcohol, 2-(4-hydroxyphenyl)ethanol, vanillyl alcohol, homovanillyl alcohol, syringyl alcohol, homosyringyl alcohol, 4-hydroxyacetophenone, acetoguaiacone, acetosyringone, 4-hydroxystyrene, 3-methoxy-4-hydroxystyrene, 3,5-dimethoxy-4-hydroxystyrene, (4-hydroxyphenyl)-1-propene, (4-hydroxyphenyl)-2-propene, eugenol, isoeugenol, syringeugenol, iso-syringeugenol, ethyl phenol, ethyl guaiacol, ethyl syringol, propyl phenol, propyl guaiacol, propyl syringol, cresol, creosol, syringyl creosol, phenol, guaiacol, 4-methylguaiacol, 4-methyl-2,6-dimethoxyphenol, guaiacol and 2,6-methoxyphenol, syringol, benzene, toluene, xylene, ethyl benzene, propyl benzene, biphenyl and pyrolytic oils, and the lignin residues are at least one chemical of biobased aromatic chemicals and biobased aromatic fuels. The lignin residues are used to provide energy production such as heat or power. The product from the lignin biomass is used in the production of other chemicals, materials, and products. The other chemicals, materials, and products are used in the production of additional chemicals, materials, and products, where at least one product from the lignin biomass comprises at least one product of achiral, racemic, and optically pure products (all claimed).    ADVANTAGE - The method is capable of easily converting lignin biomass into value-added biobased materials while minimizing waste products, thus reducing costs associated with waste disposal of lignin and lignin wastes.
