Batteries From Reused, Recycled, and Surplus Materials

Advanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

From Viscose to Lyocell‐Type Fibers: Chemical Recycling of Viscose and Modal Fibers Using the Ioncell Process

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Using the Ioncell process, the recycling of low DP textile waste via four case studies, white, blue, and black viscose and white modal fibers, was investigated. The most common man‐made cellulose fiber (MMCF) is viscose, a low DP material made of plant‐based cellulose, and it accounts for less than 6% of the total amount of textile fibers.

Displacement washing of TEMPO-oxidized softwood kraft pulp: Effects of change in fiber properties [PDF]

, 2013
Bleached softwood kraft pulp fibers were treated using TEMPO oxidation at two different dosages of NaClO. A batch of non-oxidized reference pulp was also prepared with a concentration of the tracer (Na) similar to the oxidized batches.

On Studies of Preparation of Kraft Pulp

JAPAN TAPPI JOURNAL, 1961
Using the laboratory Valley beater, the following results were obtained.1) When the beating load was constant, the beating with the high peripheral speed of beater roll required the fairly lower freeness than it of the pulp beaten with the low peripheral speed of the roll to attain the constant ratio of tearing strength to bursting strength of paper ...

Structure–Reactivity Relationship of β‐O‐4 Linkers in Lignin Model Compound Catalytic Pyrolysis

Advanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
Acid‐catalyzed pyrolysis of lignin model dimers reveals that retro‐ene and Maccoll elimination pathways compete with dehydration reactions, depending on the substituent at the β‐O‐4 linkage. We unveil these reaction mechanisms utilizing photoionization mass spectrometry with VUV synchrotron radiation.

DISPLACEMENT WASHING OF KRAFT PULP WITH VARIOUS CONSISTENCY

Cellulose Chemistry and Technology, 2020
The paper deals with the displacement washing of kraft softwood and hardwood pulps with various consistency of the pulp fibre bed. The results obtained revealed differences between the two types of kraft pulp with various morphological properties of fibres. The washing efficiency decreased with decreasing Péclet number for both kraft pulps, but, due to
