Publication number: 20250034335Abstract: Lignin is recovered from biomass or byproducts from biomass processing through the use of organic solvents and water while modifying the form or composition of the lignin. During the separation and recovery process, the lignin can be modified or integrated into a form which is more suitable for its intended use. As the lignin is suspended or is soluble within the organic solvent, the integration of materials or reactants may be more easily blended or dispersed within the lignin to improve performance, quality and overall production efficiency.Type: ApplicationFiled: March 6, 2024Publication date: January 30, 2025Inventors: David J. Winsness, Michael J. RIEBEL, Milton J RIEBEL
