Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability.

Full Sequence Bleaching with Dimethyldioxirane [PDF]
, 1995 Research work to date has shown dimethyldioxirane to be a very powerful, yet highly selective oxidant. Dimethyldioxirane bleaching may become more important in the future with legislative restrictions on chlorine based bleaching agents as it contains no ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp
Journal of Applied Polymer Science, EarlyView.This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Thermal Characteristics of Lignin Residue from Industrial Processes
BioResources, 2013 Many pulp mills and biorefineries today are focusing on the utilization of their residual lignin for economic return. Although lignin can be burned to produce energy, it also has the potential for the production of value-added products. Technical lignins

, 2022 Many materials, man-made and natural, have a composite structure, i.e. they comprise two or more constituent materials with distinct differences. Concrete is a common example. It consists of sand or gravel, cement and water. Wood is also a composite. It has strong, crystalline cellulose structures glued together by hemicelluloses and lignin. The unique

Valorization of paper sludge for bioethanol and biogas production
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...

Study of the reactivity of Kraft and organosolv lignins with 4, 4’–diphenylmethane diisocyanate and characterization of the obtained products [PDF]
, 2011 The interaction of two types of lignins: Kraft lignin (KL), isolated according to the LignoBoost process (Sweden), and Alcell organosolv (OL) lignin (Canada), with 4,4’-diphenylmethane diisocyanate (MDI) in the dry dioxane media at 25 degrees of Celsius,
