Abstract Polymeric materials featuring excellent flame retardancy are essential for applications requiring high levels of fire safety, while those based on biopolymers highly favored due to their eco‐friendly nature, sustainable characteristics, and abundant availability. This review first outlines the pyrolysis behaviors biopolymers, with particular emphasis naturally occurring ones derived from non‐food sources such as cellulose, chitin/chitosan, alginate, lignin. Then, strategies chemical modifications flame‐retardant purposes through covalent, ionic, coordination bonds presented compared. The is placed advanced methods introducing biopolymer‐based retardants into polymeric matrices fabricating materials. Finally, challenges sustaining current momentum in utilization further discussed.

The depletion of fossil fuels and environmental concerns have driven the development sustainable materials, including bio-based biodegradable plastics, as alternatives to conventional plastics. Although these plastics aid in waste management climate change mitigation, their vulnerability oxidative degradation impacts longevity, durability, performance. Natural antioxidants such tocopherols, flavonoids, tannins, extracted from plants or agri-food waste, present a alternative synthetic stabilizers by enhancing thermal stability polymers like poly(lactic acid) (PLA), poly(butylene succinate) (PBS), succinate-adipate) (PBSA), adipate-co-terephthalate) (PBAT), poly(hydroxyalkanoate) (PHA), starch-based materials. This review highlights recent advances stabilized with natural antioxidants, mechanisms action, role improving material properties for applications packaging. Additionally, it explores impact on recycling processes, advancements composite production techniques, future research directions. Bioplastics can achieve enhanced performance, reduce support circular economy incorporating antioxidants.

This study focuses on developing environmentally friendly plasticized poly(lactide) (PLA) formulations using tartaric acid and α-tocopherol at 20 wt%. The extrusion injection molding processes demonstrated the industrial applicability of these plasticizers. Mechanical tests revealed positive results for tartrate-based plasticizers, with elongation break surpassing 220 %, while succinate achieved 170 %. However, acetate showed limited PLA plasticization. Field emission scanning electron microscopy confirmed plasticization in fractured surfaces. Thermal analysis indicated a reduction PLA's glass transition temperature (Tg) from 60 °C to around 30 underscoring tartrates' exceptional efficiency. cold crystallization (Tcc) decreased all samples due enhanced chain mobility. Thermomechanical dimensional shrinkage, dimethyl tartrate (DMT) causing less pronounced effects. Generally, tartrates yielded superior properties, attributed their lower molecular weight compared α-tocopherol-derived Notably, plasticizers employed are an eco-friendly approach improve processability enhancing ductile properties.

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.
