NOVELTY - A biomass containing product comprises densified biomass particulate(s) of a given mass having no added binder, and comprising lignin-coated plant biomass fibers. The densified biomass particulate(s) has an intrinsic density equivalent to a binder-containing densified biomass particulate of the same given mass and has a smooth, nonflakey outer surface.    USE - A biomass containing product for a packaged product, a solid material, fuel or an animal feed (claimed).    ADVANTAGE - A biomass containing product has an increased resistance to deformation, an increased hardness, an increased resistance to degradation and/or an improved shelf life as compared with the binder-containing densified biomass particulate; improves digestibility of an animal feed; and increased flowability and/or a greater bulk density, and rectangular or cylindrical shape; and is greater than or equal to 21% harder with greater than or equal to 20% less variability in hardness than the binder-containing densified biomass particulate of the same given mass.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a packaged product comprising a container, and densified biomass particulates having no added binder located within the container where the quantity of densified biomass particulates has a bulk density at greater than a bulk density of an identical quantity of binder-containing densified biomass particulates; and    (2) an integrated process comprising subjecting a quantity of biomass fibers to an ammonia treatment where portion(s) of lignin contained within each fiber is moved to an outer surface of each fiber to produce a quantity of tacky biomass fibers, and densifying the quantity of tacky biomass fibers to produce densified biomass particulate(s) where the quantity of tacky biomass fibers is densified without adding binder.    DESCRIPTION OF DRAWING(S) - The drawing is a graph showing percent glucan conversion versus biomass at 6 hour, 24 hour and 72 hour for biomass samples including AFEX-pretreated corn stover, AFEX-pretreated corn stover pellets, and soaked AFEX-pretreated corn stover pellets.
