Valorization of paper sludge for bioethanol and biogas production

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 817-825, March/April 2026.
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 ...

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

Comparative Evaluation of Soda and Nitrate‐Alkaline Pulping of Hemp, Flax, and Sisal Post‐harvest Biomass

ChemistryOpen, Volume 15, Issue 3, March 2026.
The study compares hemp, flax, and sisal as nonwood raw materials for pulp production using soda and nitrate‐alkaline cooking. It evaluates chemical composition, cellulose crystallinity, yield, delignification, and paper strength. Sisal showed the highest tensile performance, while the choice of cooking method significantly influenced the quality and ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Oxidative depolymerisation of kraft lignin

, 2023
The production of green hydrogen may be greatly aided by the use of an alternative anode reaction replacing oxygen evolution to increase energy efficiency and concomitantly generate value-added products. Lignin, a major component of plant matter, is accumulated in large amounts in the pulp and paper industry as waste.
