1. A process comprising:
- subjecting a quantity of plant biomass fibers to a pretreatment to cause at least a portion of lignin contained within each fiber to move to an outer surface of said fiber, wherein a quantity of pretreated tacky plant biomass fibers is produced; and
densifying the quantity of pretreated tacky plant biomass fibers to produce one or more densified biomass particulates, wherein said biomass fibers are densified without using added binder.

24. A process comprising:
-
subjecting a quantity of plant biomass fibers to an ammonia pretreatment to cause at least a portion of lignin and/or hemicellulose contained within each fiber to move to an outer surface of said fiber to produce a quantity of pretreated tacky plant biomass fibers, wherein the ammonia pretreatment generates reduced levels of lignin and/or hemicellulose in an interior of said fiber and increased lignin and/or hemicellulose on its surface as compared with pretreatment levels of lignin and/or hemicellulose, wherein said surface lignin and/or hemicellulose has a degree of tackiness; and densifying the quantity of pretreated tacky plant biomass fibers to produce one or more densified biomass particulates, wherein the quantity of said biomass fibers is densified without using added binder. - View Dependent Claims (25, 26, 27, 28, 29, 33, 34, 35, 36, 37, 38, 39, 40)

- 30. The process of claim 243 wherein said densified biomass particulates have an increased gross caloric value as compared with densified biomass particulates containing untreated plant biomass fibers.
- 41. A process comprising using one or more densified biomass particulates in a bioproduct production facility to produce a product, wherein said densified biomass particulates are each comprised of a plurality of pretreated lignin-coated plant biomass fibers containing a trace amount of base, wherein said densified biomass particulates have a substantially smooth, non-flakey outer surface and contain no added binder.
