Abstract

Up to now, recycling has been opposed to biodegradability, although these two end-of-life options are complementary. If combined in an integrated system, recycling creates an after-use economy, while biodegradability eradicates definitely the issues of environmental spreading of the persistent plastic wastes. This paper reviews the current state on recyclability of some promising biodegradable polyesters, polylactide acid (PLA), polyhydroxyalkanoates (PHAs), bio-polybutylene succinate (PBS) and polybutylene adipate terephthalate (PBAT), with emphasis on mechanical recycling. The effect of the mechanical reprocessing (multiple extrusion or injection-molding) on the chemical structure and thermomechanical properties of the polymers is reported. In addition, the application of upgrading strategies such as blends and/or composites to improve polyesters recyclability are considered. A further decontamination step is studied in order to achieve food contact aptitude in mechanical recycling for food packaging application. Finally, the challenges that should be faced in the future, to promote the recyclability of biodegradable polyesters are addressed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
