A Solvent‐Free Approach for the Mechanochemical Upcycling of Bio‐ and Fossil‐Based Polyesters Into Value‐Added Chemicals and Bio‐Based Plasticizers

open access: yesChemSusChem, Volume 19, Issue 17, 14 September 2026.
Mechanochemical upcycling of bio‐ and fossil‐based polyesters with alcohols and amines using MeONa as the catalyst selectively produces synthetically useful diesters and diamides, giving only alcohols as byproducts. This green and efficient protocol is readily scalable and can be transferred to the upcycling of polyester‐based postconsumer waste ...

Thermally Processable, Transparent, Mechanically Tunable and Robust Bioplastics From Wastepaper

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
Unlike conventional inefficient or low‐value wastepaper recycling, a directional transformation strategy is employed to convert whole wastepaper into intact bioplastics with tunable mechanical properties in our work. These bioplastics can be processed into flexible bags or rigid containers and exhibit high transparency, water resistance, repairability,
