This study aims to optimize the operational variables influencing incorporation of Hesperidin nanoparticles (HSP NPs) into poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) for manufacturing mixed matrix membranes (MMMs) oily wastewater treatment. An optimization method was employed determine optimal values key process factors achieve specific flux and rejection rates exceeding required levels. Statistical techniques such as response surface methodology (RSM) analysis variance (ANOVA) were used enhance performance on a larger scale. research investigated impact operating parameters oil PLA/PBAT/HSP across all samples. The studied included HSP NPs content (0-0.05 wt.%), concentration (100-300 ppm), transmembrane pressure (1.5-3.5 bar). A mathematical model calculating (%) developed. findings indicated that PLA/PBAT/HSP-based MMMs demonstrated efficiency, achieving 121 LMH 98.53%. conditions 0.03 wt.% HSP, an 158.28 ppm, 3.5 bar yielded best response. results show exhibited enhanced separation properties, making them suitable treating in various applications.

Abstract Biopolymers, derived from renewable resources such as plants, animals, and microorganisms, are emerging sustainable alternatives to traditional petroleum‐based polymers. The review examines the key characteristics of biopolymers, including their biodegradability, biocompatibility, potential for carbon neutrality. These crucial determining suitability different packaging applications reduce environmental pollution. While acknowledging promise also addresses challenges production costs, scalability issues, performance limitations. Strategies enhance biopolymer performance, plasticization, blending, nanomaterial reinforcement, discussed. Interestingly, highlights field active intelligent systems, which incorporate antimicrobial agents sensors extend shelf life monitor food quality in real‐time. emphasizes importance cycle assessments evaluating overall impact biopolymer‐based compared conventional alternatives. In conclusion, this provides an overview current state research identifies areas future investigation. By synthesizing knowledge, identifying challenges, highlighting opportunities, contributes ongoing efforts create a more circular industry.

Rise in population, urbanisation, and socioeconomic growth have led to amplified food consumption, globally. Increased consumption of vegetable oil for frying cooking various items households, restaurants, cafeterias instigates the generation millions tons waste (WCO) across jurisdictions. Inappropriate disposal hazardous WCO blocks drainages, contaminates waterbodies, exacerbates environmental degradation. Conversion into valuable products remains a realistic sustainable strategy management. This review delves recent advances deployment as low-cost feedstock non-fuel such biolubricant, bioplasticizer, bioasphalt, 3D printing resin. In this regard, work describes generation, collection, pretreatment, characterisation products. addition, major challenges future research directions conversion are highlighted before conclusion. The study recommends commissioning multidisciplinary unearthing robust collection systems, novel pretreatment methodologies, innovative technologies WCO.

The winery waste of a white grape was extracted in two different ways to produce extracts, one containing the natural oil and without it; goal work determine positive or negative influence content extract on its stabilization effect efficiency. polyphenol extracts moderate, but their DPPH assay proved antioxidant effect. were added polyethylene concentrations between 0 2000 ppm, stabilizing efficiency determined multiple extrusion experiments. stabilized adequately; only slightly smaller than that commercial hindered phenolic antioxidant, Irganox 1010. solubility PE is much larger, 280 flavonoid-type quercetin (15 ppm). presence had slight efficiency, properties more beneficial harmful. It decreases interactions among molecules, improves processability polymer, increases homogeneity slightly. Accordingly, an extraction step can be saved during preparation product, thus offering economic advantage.

Under dual pressures of energy scarcity and environmental pollution, the biobased polyester poly(ethylene furanoate) (PEF) is poised to dominate industry in future, overtaking conventional petroleum-based polyesters. Nonetheless, PEF discoloration a critical impediment its commercial success. Esterification reaction 2,5-furandicarboxylic acid (FDCA) ethylene glycol (EG) was developed at varying temperatures, yielding esterified products exhibiting degrees discoloration. The main compounds minor impurities all samples were accurately separated identified using ultrahigh-performance liquid chromatography/high-definition mass spectrometry (UPLC-HDMS) techniques. chemical structure yellowing component determined by secondary (MS/MS), Fourier transform infrared (FTIR) spectrometry, nuclear magnetic resonance (NMR) spectrometer. It can be concluded that different forms decarboxylated byproducts produced during esterification polycondensation, which resulted PEF. At same time, also present alcoholysis brown chips but absent white PET chips. These results clearly demonstrate direct relationship between decarboxylation. Overall, this work offers theoretical support insights for future research into discoloration, establishing solid foundation further development application.
