Chemical recycling and repolymerization of poly(ethylene terephthalate), poly(ethylene furanoate), and their copolyesters.
Article in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Replacing fossil-based plastics with bio-based ones is vital for future sustainability. However, bio-based plastics are not recycled within current recycling feeds, as polymers generally do not mix. Hence, mixing bio-based polymers with existing mechanical recycling feeds would yield materials of poor quality. For efficient recycling and as drop-in alternatives, bio-based polymers must have similar properties to the polymers in the feed they are mixed with. Chemical recycling and repolymerization can overcome incompatibility challenges by yielding copolymers. However, the question is: are the properties of the copolymers similar to those of the virgin homopolymers? Poly(ethylene furanoate) (PEF), a bio-based polymer, has similar properties to poly(ethylene terephthalate) (PET), such as high melting temperature, thermal stability, crystallinity, and gas-barrier properties. Both PEF and PET can be chemically recycled by solvolytic methods, and the obtained monomers can be repolymerized into copolymers that have similar properties to the virgin polymers. We have chemically recycled PET and PEF, repolymerized the recyclates into homo- and copolymers, and investigated the properties of the resulting polymers. We were able to repolymerize high-molecular weight polymers (
