Green Extraction and Fractionation of Chestnut Wood Waste: A Sustainable Pathway to Biopolymers and Antimicrobial Solutions

open access: yesChemSusChem, EarlyView.
A sustainable valorization of chestnut wood waste is proposed through microwave‐assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin‐rich fraction, used to synthesize a PVA‐based biopolymer ...

How to Produce Green Hydrogen from Olivine and Seawater? By Ultrasound

open access: yesChemSusChem, EarlyView.
Power ultrasound provides efficient production of green hydrogen from olivine and seawater under near‐ambient conditions. The sonochemical alteration of olivine involves particle fragmentation, the removal of the passivating layer, and local, transient heating in the vicinity of collapsing bubbles.

Uncovering the Residual Electrolyte Quantity in Recycled Battery Black Mass via Liquid Chromatography Tandem Mass Spectrometry and Ion Chromatography‐Conductivity Detection

open access: yesChemSusChem, EarlyView.
A workflow for the quantification of electrolyte residues, including linear and cyclic carbonates, conducting salt and selected degradation products from shredded lithium ion battery material black mass, is developed. The results demonstrate that shake extraction using the aprotic acetonitrile is the most suitable sample preparation technique with over
