  • Lactone monomers for recyclable polyesters are conventionally synthesized via endergonic, non-oxidative dehydrocyclization of fossil-derived diols in the vapor phase over precious-metal catalysts at elevated temperatures. Here, the authors demonstrate a low-temperature, solvent-free, oxidative route to lactones from bio-derivable liquid diols using earth-abundant calcium-copper mixed-metal oxide catalysts.

  • Acetic acid efficiently depolymerizes aliphatic and aromatic epoxy-amine thermosets used in carbon fibre-reinforced polymers (CFRPs) to yield recoverable monomers and pristine carbon fibres, which, based on process modelling, techno-economic analysis and life cycle assessment, could enable industrial recycling of CFRPs.
