NOVELTY - Generating (I) fuel or fuel blending product comprises e.g.: recovering fuel or fuel blending product and residual product from feed comprising algae-derived biomass; performing fermentation pretreatment on at least a portion of residual product; and fermenting at least portion of pretreated residual product to produce at least one oxygenate or fermentation residue, where at least portion of oxygenates are used as input stream (156) for recovering fuel or fuel blending product, or as input stream for pretreating residual product.    USE - The method is useful for generating fuel (biofuels) or fuel blending product (all claimed) including lubricants, chemical products, and/or other products having a renewable character.    DETAILED DESCRIPTION - Generating (I) a fuel or fuel blending product comprises: recovering a fuel or fuel blending product and a residual product from a feed comprising algae-derived biomass; performing a fermentation pretreatment on at least a portion of the residual product; and fermenting at least a portion of the pretreated residual product to produce at least one oxygenate or a fermentation residue, where at least a portion of the oxygenates are used as an input stream (156) for recovering the fuel or fuel blending product, or as an input stream for pretreating the residual product or as input streams for both recovering the fuel or fuel blending product and pretreating the residual product. INDEPENDENT CLAIMS are also included for:    (1) generating (II) a fuel or fuel blending product comprising recovering fuel or fuel blending product and residual product from feed comprising algae-derived biomass, digesting at least a portion of the residual product to form a digestion gas and a digestion residue, and fermenting a feed comprising non-algal biomass to produce the oxygenates and a fermentation residue, where the one or more oxygenates are used as an input stream for recovering the fuel or fuel blending product;    (2) generating (III) biofuels, comprising (a) growing algae in an algae growth environment, (b) recovering a first fuel or fuel blending product and a residual product from the feed comprising algae-derived biomass derived from the algae growth environment, and (c) converting non-algal biomass feed into a second fuel or fuel blending product, where the conversion includes use of at least one product or energy output from the growing of algae or recovering of the first fuel or fuel blending product as a chemical, energy, or mechanical input for the conversion, at least one compound produced in the conversion of the non-algal biomass into a second fuel or fuel blending product is used as a nutrient for the algae growth or as a reagent for the recovery of the first fuel or fuel blending product; and    (3) generating (IV) biofuels, comprising steps (a)-(b) as above per se, converting non-algal biomass feed into second fuel or fuel blending product, and feeding carbon dioxide generated from the conversion of the non-algal biomass feed to the algae growth environment.
