Among plastics, poly­(ethylene terephthalate) (PET) is a polymer that stands out as a significant source of pollution due to its extensive use in disposable packaging. Strategies involving PET upcycling can significantly contribute to the reduction of plastic waste. This perspective presents a recent trend in PET upcycling, focusing on the combination of PET waste with polysaccharides to obtain high-value-added materials. The influence of adding different types of polysaccharides and various preparation methods on the properties of recycled PET (rPET)-based membranes is thoroughly discussed. In addition, the relationship between the properties and applications of the rPET/polysaccharide membranes is addressed. In addition to demonstrating the potential and versatility of these materials, this review identifies challenges related to their industrialization, sustainability, and circularity, while also proposing future research directions for PET upcycling with polysaccharides. ## Full-text entities - **Genes:** PCM1 (pericentriolar material 1) [NCBI Gene 5108] {aka PTC4, RET/PCM-1}, PPL (periplakin) [NCBI Gene 5493] - **Diseases:** infection (MESH:D007239), CA (MESH:D003877) - **Chemicals:** EG (MESH:D019855), Polysaccharide (MESH:D011134), nitrogen (MESH:D009584), DCM (MESH:D008752), poly(ethylene glycol) (MESH:D011092), Cellulose acetate (MESH:C005062), monosaccharide (MESH:D009005), chitin (MESH:D002686), triglyceride (MESH:D014280), Polymer (MESH:D011108), Amylopectin (MESH:D000687), metal (MESH:D008670), RB (MESH:D012413), d-mannose (MESH:D008358), ricinoleic acid (MESH:C030521), eucalyptol (MESH:D000077591), Amylose (MESH:D000688), methanol (MESH:D000432), Chitosan (MESH:D048271), diltiazem (MESH:D004110), Cr(VI) (MESH:C074702), NH3 (MESH:D000641), Alginate (MESH:D000464), O (MESH:D010100), PDA (MESH:C568283), PEG-400 (MESH:C000595213), acetic acid (MESH:D019342), ethanol (MESH:D000431), XA (MESH:C002563), aldehyde (MESH:D000447), 13C (MESH:C000615229), water (MESH:D014867), dimethyl terephthalate (MESH:C004782), Schiff base (MESH:D012545), MB (MESH:D008751), CuCl2 (MESH:C029892), polyester (MESH:D011091), chromium (MESH:D002857), amine (MESH:D000588), Starch (MESH:D013213), TFA (MESH:D014269), oil (MESH:D009821), hydrocarbon (MESH:D006838), N-acetyl-d-glucosamine (MESH:D000117), 1,1,3,3-tetramethylguanidine (MESH:C477069), TPA (MESH:C011363), CNF (MESH:C071110), 1H (-), CO (MESH:D002368), imine (MESH:D007097), d-glucuronic acid (MESH:D020723), glutaraldehyde (MESH:D005976), acetaldehyde (MESH:D000079), PET (MESH:D011093), H (MESH:D006859), Cellulose (MESH:D002482), MG (MESH:D008274), beta-d-mannuronic acid (MESH:C008324), d-glucosamine (MESH:D005944), d-glucose (MESH:D005947) - **Species:** Xanthomonas campestris (species) [taxon 339], Pseudomonas aeruginosa (species) [taxon 287], Candida albicans (species) [taxon 5476], Staphylococcus aureus (species) [taxon 1280], Phaeophyceae (brown algae, class) [taxon 2870], Homo sapiens (human, species) [taxon 9606], Solanum tuberosum (potatoes, species) [taxon 4113], PX clade (clade) [taxon 569578] ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/PMC12946979/full.md ## Figures 12 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12946979/full.md ## References 113 references — full list in the complete paper: https://tomesphere.com/paper/PMC12946979/full.md --- Source: https://tomesphere.com/paper/PMC12946979
