3D‐Printed Hydrogels from Recycled Cellulose for Biomedical Applications

ChemSusChem, Volume 19, Issue 1, January 2026.
Cellulose recovered from textile waste was transformed into photo‐crosslinkable hydrogels and processed by light‐induced 3D‐printing. The resulting elastic, shape‐stable structures demonstrate high printing fidelity and highlight the potential of recycled textiles as a more sustainable source for hydrogel‐based wound patch materials.

Open‐ and Closed‐Loop Recycling of Polyesters and Post‐Consumer Waste Under Industrially Relevant Conditions Using Bisguanidine Organocatalysts

ChemSusChem, Volume 19, Issue 1, January 2026.
The chemical recycling of polylactide (PLA), polyethylene terephthalate (PET), and polycaprolactone (PCL) is performed using bisguanidine organocatalysts. Intensive kinetic studies of the methanolysis and ethanolysis of PLA were performed. The most active organocatalyst was successfully applied in the depolymerization of ternary plastic mixes of PLA ...

Chemical Recycling of Polycarbonate Acrylonitrile Butadiene Styrene Blends via Organocatalyzed Acetolysis

ChemSusChem, Volume 19, Issue 1, January 2026.
Polycarbonate/acrylonitrile butadiene styrene (PC/ABS) has been chemically recycled by depolymerizing the PC via base‐catalyzed acetolysis to yield acetylated bisphenol A. Unlike alternative methods, the presence of ABS did not hinder acetolysis, allowing recovery of ABS from these multimaterials. A new depolymerization catalyst, 4‐pyrrolidinylpyridine,

Recycling of Polyurethane Waste: Facile Hydrothermal Conversion Using Acidic and Basic Additives

ChemSusChem, Volume 19, Issue 1, January 2026.
Ethylenediamine efficiently catalyses the hydrothermal recycling of polyurethane (PU) into monomers. The NH functional groups promote carbamic acid decomposition via zwitterion interactions, outperforming inorganic acids and bases, and enabling selective depolymerisation of PU under mild conditions for circular chemical utilisation.
