Abstract: Cellulose particles treated with a bio-based surfactant can be compounded into a polymer composite having improved mechanical properties, such as tensile strength and/or tensile modulus. Treatment can be integrated into an industrial scale continuous cellulose particle production process, and the process provides one or more of reduced environmental impact, reduced energy consumption, reduced chemical consumption, reduced water consumption, reduced processing/operational cost, reduced capital investment, increased output, improved fiber dispersion in the polymer matrix and improved thermal degradation properties of the composite.

Abstract: Lignin pellets comprising fused lignin are described herein. The lignin pellets may further comprise a processing aid, and/or a surfactant, and/or a chemical modifying agent, and/or a compatibilizer and/or a thermoplastic polymer. An extrusion process for producing the lignin pellets and their use in the manufacture of lignin thermoplastic blend products, polyols, polyphenols, polyaromatics and polyurethanes is also disclosed herein. The extruded lignin pellet may be dry-blended with additional thermoplastic and/or additive and then directly processed using processes such as injection molding, compression molding, extrusion, extrusion coating, blowing, thermoforming, stamping, foaming, fiber drawing, calendering or rolling.

Abstract: A method for producing high-purity lignin based aerogels and carbon aerogels having improved physical and operational properties. Such high-purity lignin based carbon aerogels can be formaldehyde free and can be used for a wide range of applications including supercapacitor electrodes for supercapacitor cells.

Abstract: This disclosure includes adhesive compositions comprising lignin, as well as methods of making such adhesive compositions, methods of making glyoxalated lignin or glyoxalating lignin-fiber mixtures, particularly glyoxalated kraft lignin, and methods of making lignocellulosic composite products including the present adhesive compositions.
