In this work, composites based on poly(3-hydroxybutyrate-3-hydroxyvalerate) (PHB-HV) and waste wood sawdust (SD) fibers, a byproduct of the wood industry, were produced by melt extrusion and characterized in terms of processability, thermal stability, morphology, and mechanical properties in order to discriminate the formulations suitable for injection molding. Given their application in agriculture and/or plant nursery, the biodegradability of the optimized composites was investigated under controlled composting conditions in accordance with standard methods (ASTM D5338-98 and ISO 20200-2004). The optimized PHB-HV/SD composites were used for the production of pots by injection molding and their performance was qualitatively monitored in a plant nursery and underground for 14 months. This study presents a sustainable option of valuation of wood factory residues and lowering the production cost of PHB-HV-based compounds without affecting their mechanical properties, improving their impact resistance and biodegradability rates in terrestrial environments.

“…The oil has also shown synergistic effects by inhibiting the levels of thromboxane B2 and platelet aggregation in lung and spleen tissues in Wistar rats ( Raghavendra and Akhilender Naidu, 2011 ). Recently, an oil-based polymeric material has grabbed immense attention and extensive research work is being carried out to manufacture these biopolymeric materials owing better chemical and physical properties ( Imre and Pukánszky, 2013 ). Several biodegradiable polymers such as polyurethane, polyesteramide, polyetheramide, alkyd, epoxy, polystyrene and polyvinyl alcohol have been used to prepare these oil-based biopolymers ( Song et al, 2018 , De Conto et al, 2020 ).…”

A substantial interest has been manifested in utilizing oil/metal oxide hybrid bionanocomposite, especially organic/ inorganic to design different biomedical applications. The present study reports the synthesis, characterization, antibacterial and anticancer properties of biogenic silver nanoparticles (AgNPs) and L.satiVum oil/PEG/Ag-MgO bionanocomposite. The fabricated AgNPs and L.sativum oil/PEG/Ag-MgO bionanocomposite were characterized by employing different spectroscopic (UV, FTIR, XRD) and microscopic (TEM, SEM) techniques. The particle size analysis showed that the mean size of 16.32 nm for AgNPS and 13.45 nm L.satiVum oil/PEG/Ag-MgO, indicating the excellent dispersion of Ag-MgO nanoparticles in the PEG– L.satiVum oil matrix. The antimicrobial activity of AgNPs and polymeric bionanocomposite was investigated against two pathogenic bacteria. The highest antibacterial effect was observed for bionanocomposite towards Gram-positive Staphylococcus aureus (27 mm) and Gram-negative Escherichia coli (25 mm) at 40 µg/well. The bionanocomposite completely vanished the bacterial growth (100%) at 80 µgmL −1 concentrations. Moreover, the AgNPs and polymeric bionanocomposite was evaluated for anticancer activity against human cervical cancer cells (HeLa cells) at different doses (50, 250, 500, and 1000 µgmL −1 ). The results showed polymeric bionanocomposite was stronger in inducing the HeLa cancer cell death than AgNPs. Overall, the fabricated L.satiVum oil/PEG/Ag-MgO bionanocomposite serve as a potential antimicrobial and anticancer agent and could be used in the development of novel drugs and health care products in near future.

ÖzThis paper investigates Natural Fiber Thermoplastic Composites (NFTC) which take attention of the researchers and the market having aesthetic and low maintenance properties in many applications. Additive usage is an increasing application for NFTC production to get into the novel markets satisfying strong performance requirements and life stability interests of users. In this article, polymer blends from natural resources including bio-based additives for polymer composites were introduced. Afterwards, favorite additive types and most effective pelletizing processes in literature were analyzed to improve composite productivity. At the end of the paper, the common NFTC production technologies are discussed. A specially designed compounding extruder which is designed to overcome production difficulties and supply high processing performances is introduced. At the end of conducted experiment, the obtained production output rate is presented. Bu çalışma, estetik ve düşük bakım özelliklerine sahip birçok uygulamada araştırmacıların ve pazarın dikkatini çeken Doğal ElyafTermoplastik Kompozitleri (NFTC) araştırmaktadır. Katkı kullanımı, NFTC üretimi açısından giderek artış gösteren, güçlü performans gereksinimlerini karşıladığı için de yeni pazarlara giriş imkanı sağlayan, uzun ömürlü ve kullanıcı beklentilerini tatmin eden bir uygulamadır. Bu çalışmada, polimer kompozitlerin biyo-bazlı katkıları dahil olmak üzere doğal kaynaklardan elde edilen polimer karışımlar tanıtılmıştır. İlaveten, kompozit üretkenliğini arttırmak için favori katkı maddeleri ve literatürdeki en etkili peletleme işlemleri analiz edilmiştir. Çalışmanın sonunda, yaygın olarak kullanılan NFTC üretim teknolojileri tartışılmıştır. Çeşitli imalat zorluklarının üstesinden gelen ve yüksek işlem performansları sağlayan bir imalat için özel olarak tasarlanmış karıştırıcı bir extruder tanıtılmıştır. Deneysel bir uygulama sonunda ulaşılan üretim kapasitesi paylaşılmıştır.
