Summary: Blending of plasticized hydroxypropyl cassava thermoplastic starch (TPS) with polybutylene adipate terephthalate (PBAT) via blown-film extrusion was studied. Higher DS values were found to increase film clarity and glossy surface, reduce crystallinity, improve hydrophilicity, mechanical properties and compatibility between PBAT and TPS. Modified DS in hydroxypropyl starch efficiently improved clarity, mechanical and barrier properties of bioplastic packaging.

Summary: This study investigated the production of LLDPE/OP films using blown film extrusion and evaluated the effect of OP content on film morphology and properties. The results showed that blown LLDPE/OP films containing up to 11.5% OP could be produced, with similar water barrier, crystallinity, and melting temperature to neat LLDPE films, but lower tensile strength and elongation at break. The addition of OP also enhanced the UV and visible light blocking capacity of the films.

Summary: Poly (butylene adipate-co-terephthalate) (PBAT) is a biodegradable polymer used in the food packaging industry. A PBAT composite film was prepared using a green approach, with epoxidized soya bean oil (ESO) and encapsulated lignin (Lig)/tannic acid (Ta) as fillers. The addition of ESO-Lig-Ta improved tensile strength, reduced UV transmission, and decreased water vapor and oxygen transmission rate. The composite film showed potential for short-lived fresh food packaging and long-term preservation of dry food products.

Summary: Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a biodegradable thermoplastic with promising mechanical properties. Its high cost and brittleness have limited its extensive applications. This study used hemp powder residue (HP) and polybutylene adipate-co-terephthalate (PBAT) as additives to optimize the properties and cost of PHBV. The developed biocomposite demonstrated similar performance to conventional plastics, making it suitable for rigid packaging and container applications.

Summary: Blown-extruded starch/polyester blends with added alpha-tocopherol showed promising potential as active food packaging materials. The antioxidant interfered with the polymer matrix organization, leading to lower tensile strength and elongation at break, while not affecting thermal stability. Films with the lowest antioxidant concentration released most of the alpha-tocopherol, indicating efficient active packaging performance.

Summary: Micro Fibrillated Cellulose (MFC) has gained interest in both academia and industry, but there are challenges in utilizing it for industrial MFC/biocomposite applications. The agglomeration of MFC during processing is a major issue. Plasticizers have been used to optimize the extrusion process and counterbalance the stiffness caused by MFC addition. However, the migration of plasticizers from the finished product needs to be evaluated to avoid negative effects. This study evaluated the role of MFC in controlling plasticizer migration and confirmed the expected benefits through mechanical and thermal analysis.

Summary: This article introduces a facile way to remove the non-polymeric layers and investigates the effect of the repetitive extrusion process on the processability and mechanical properties of recycled polycarbonate. The removal of the non-polymeric layers can be easily achieved through a thermo-mechanical treatment in a basic solution containing ammonia. The process is considered green as it is carried out at low temperature with a small amount of water and ammonia, saving energy and water. The properties of the polycarbonate remain good if mechanical recycling is conducted after drying the post-consumer polycarbonate.

Summary: The photo-oxidation of polypropylene was studied at different temperatures and in different environments. The oxidation reactions were found to be strongly influenced by the availability of oxygen and the temperature. The degradation was fastest in air, followed by sea water and distilled water. Increasing the temperature significantly increased the degradation kinetics due to decreased oxygen solubility.

Summary: By using biodegradable polymers instead of fossil-derived polymers in certain applications, the release of carbon dioxide into the environment can be greatly reduced. In this study, prototypes of aquaculture trays were produced using the biodegradable polymer Mater-Bi-(R) through injection molding. Characterization tests revealed that the polymer used has suitable properties for producing tools for aquaculture applications. Additionally, the samples underwent a biodegradation test in conditions that simulate the marine environment, showing a relatively low degradation rate for the thick molded samples.

Summary: Not recycling or recovering waste results in the loss of raw materials, but recycling plastics can reduce this loss and greenhouse gas emissions, supporting the decarbonization of plastic. However, recycling mixed plastics is challenging due to their incompatibility. This study examined the effect of temperature, rotational speed, and time on the morphology, viscosity, and mechanical properties of heterogeneous mixed polymers, including PE, PP, PS, and PET, to understand the behavior of these blends. The results showed that the blends had a brittle behavior, which improved slightly at lower temperatures and higher rotational speeds. A brittle-ductile transition was observed with increased mechanical stress, attributed to decreased particle size and the formation of copolymers.

Summary: Polymers are influenced by various environmental stresses during processing and usage, resulting in changes in their chemical and molecular structure as well as morphology. The main observed changes are reduction in molecular weight and the formation of double bonds and oxygenated groups due to degradation. These changes dramatically modify the macroscopic properties, especially in the recycling process of post-consumer plastic products.

Summary: This paper investigates the impact of reprocessing on the rheological and mechanical properties of a biocomposite. The results reveal that increasing the number of extrusions leads to a decrease in viscosity and molecular weight of the matrix and biocomposite. Additionally, the mechanical properties, such as tensile strength and elongation, decrease with the number of extrusions for the matrix, while the biocomposite shows a temporary increase in these properties after the first extrusion, followed by a slight decrease but still higher values compared to the virgin biocomposite.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
