    Abstract: Cellulose precursor materials may be refined (e.g., fibrillated) in an ethanol medium, or other solvent medium, instead of water. Following refining, the solvent may be removed and recycled prior to incorporation into another material, or optionally, following such incorporation. The solvent may assist the incorporation of nanocellulose into another material (e.g., a polymer) for a composite, for example. In some variations, a process comprises fractionating a biomass feedstock in the presence of an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; mechanically treating the cellulose-rich solids, in the presence of a refining solvent, to form cellulose fibrils and/or cellulose crystals, thereby generating a nanocellulose material; recovering and recycling the refining solvent; and recovering the nanocellulose material or incorporating the nanocellulose material into a composite material.

    Abstract: A polymer-nanocellulose-lignin composite as disclosed comprises a polymer, nanocellulose, and lignin, wherein lignin forms a hydrophobic interface between the polymer and the nanocellulose. In some variations, a process is disclosed for producing a polymer-nanocellulose-lignin composite material, comprising: fractionating lignocellulosic biomass in the presence of an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin, wherein lignin deposits onto fiber surfaces or into fiber pores; mechanically treating the cellulose-rich solids to form a hydrophobic nanocellulose material comprising cellulose fibrils and/or cellulose crystals; hydrolyzing the hemicellulose to generate fermentable hemicellulosic sugars; fermenting the fermentable hemicellulosic sugars to generate a monomer or monomer precursor; polymerizing the monomer to produce a polymer; and combining the polymer with the lignin-coated nanocellulose to generate a polymer-nanocellulose-lignin composite material for use in a wide variety of products.

    Abstract: The disclosed invention is a modification of the AVAP® technology, employing CO2 (or derivatives thereof) rather than SO2 in the cooking liquor. In some variations, the invention provides a process for fractionating cellulosic biomass into cellulose, hemicellulose, and lignin, comprising: fractionating the feedstock in the presence of a solvent for lignin, carbon dioxide, and water, to produce a liquor containing hemicellulose, cellulose-rich solids, and lignin; substantially removing the cellulose-rich solids from the liquor; hydrolyzing the hemicellulose contained in the liquor, to produce hemicellulosic monomers; hydrolyzing at least some of the cellulose-rich solids to produce glucose (or recovering the cellulose-rich solids as a cellulose product); recovering the hemicellulosic monomers to produce fermentable sugars; and recovering the lignin which may be in the form of a lignocarbonate.
