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

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

Environmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...
