NOVELTY - Biorefining method comprises providing lignin biomass, processing the lignin biomass, and producing at least one product from the lignin biomass.    USE - The method is useful for producing biobased chemicals, biofuels such as alkanes, alkenes, cycloalkanes, cycloalkenes, alkyl esters or benzene, and lignin residues from lignin sources including waste lignin (claimed).    ADVANTAGE - The method is capable of recycling the biobased chemicals thus minimizing waste products in an environmental friendly and economical manner.    DETAILED DESCRIPTION - Biorefining method comprises: either providing lignin biomass, processing the lignin biomass, and producing at least one product from the lignin biomass; or providing lignin biomass comprising at least one biomass of woody plant biomass, agricultural plant biomass, cultivated plant biomass, kraft pulping biomass, sulfite pulping biomass, soda pulping biomass, cellulosic ethanol refinery biomass, sugar cane mill biomass, lignin residue biomass and waste biomass, processing the lignin biomass with chemical-induced processing provided by chemical-induced processing, catalytic oxidative lignin depolymerization processing and catalytic hydroprocessing, processing the lignin biomass with catalytic hydroprocessing from at least one process of catalytic reduction processing, catalytic hydrodeoxygenation processing and catalytic/dehydrogenation processing, processing of the lignin biomass from at least one catalytic process to selectively provide at least one product which retains at least 77% of the carbon atom structure of the lignin biomass, functionalizing the lignin biomass prior to producing at least one product from the lignin biomass, producing at least one product from the lignin biomass comprising at least one product of biobased chemicals, biobased fuels and lignin residues, producing products from the lignin biomass comprising at least one chemical of aryl aldehydes, aryl carboxylic acids, aryl ketones, aliphatic carboxylic acids, phenols, alkyl phenols, alkenylphenols, benzene, toluene, xylenes, mesitylenes, biaryls, aryl alkanes, aryl alkenes, alkanes, alkenes, cycloalkanes, cycloalkenes, alkyl esters and performance chemicals, reducing the waste product of the lignin biomass, where the lignin biomass has a weight and the waste product of the lignin biomass is less than 20% of the lignin biomass weight, producing energy utilizing the lignin residues, producing energy utilizing the waste product of the lignin biomass biomass, recovering and recycling caustic from the processing of the lignin, and using at least one product from the lignin biomass in the production of other derivative chemicals, materials and products, where choosing of a source of the lignin biomass provides a selective production of at least one of the products from the lignin biomass.
