Special Issue Information

Dear Colleagues,

This Special Issue aims to highlight recent developments in starch and lignocellulosic-based materials, emphasizing their potential application as sustainable alternatives to synthetic polymers. These bio-based materials are garnering enhanced interest due to their renewability, biodegradability, and functional versatility across a wide range of applications, including packaging, biocomposites, pharmaceuticals, and energy. This Special Issue will explore advances in extraction, modification, processing, and characterization techniques that enhance their performance and broaden their applicability. The scope of this Special Issue includes chemical and enzymatic modifications, thermoplastic blends, nanostructuration, the development of hybrid materials, and innovations in mechanical and barrier properties. We particularly welcome contributions that address the challenges of scalability, stability, and environmental impact. By compiling innovative research from academia and industry, this Special Issue will serve as a platform for fostering innovation and collaboration in the development of next-generation materials from starch and lignocellulosic biomass.

Compatibilizers that enhance sustainability and improve the miscibility of polymer blend components have garnered significant attention. This study investigates the difference between the synthetic chain extender Joncryl® ADR 4468 and the natural epoxidized linseed oil (ELO) Merginat 8510100 as compatibilizers for thermoplastic starch/poly (butylene succinate) (TPS/PBS) blends. Blends containing 40% TPS and 60% PBS were prepared with 1, 3, and 5 phr of each compatibilizer, along with a reference with no additives. The properties of these blends were evaluated using tensile testing, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), rheology, and scanning electron microscopy (SEM). The findings indicate that while Joncryl® ADR 4468 significantly improved tensile strength, it also resulted in a brittle fracture. In contrast, ELO batches exhibited greater ductility, albeit with lower tensile strength. These differences are attributed to the chain extension and minor cross-linking effects of Joncryl® ADR 4468, compared to the increased chain mobility arising from ELO’s plasticizing and compatibilizing actions. Supporting evidence for these observations includes increased cold crystallization temperature (Tcc) and melting temperature (Tm), greater storage modulus along with higher complex viscosity, strengthened interfacial adhesion, and fewer morphological defects in Joncryl® ADR 4468 blends. These results highlight the importance of selecting an appropriate compatibilizer based on specific application requirements. Overall, this study addresses the knowledge gap regarding the loadings of Joncryl® ADR 4468 and ELO in TPS/PBS blends and provides a basis for further optimization strategies, such as the incorporation of binary compatibilizers, alternative grafting-based compatibilizers, and twin-screw blending modifications.

Starch is one of the most abundant biopolymers in nature and is widely utilized across various industries, including food, pharmaceuticals, textiles, and packaging. Its attractiveness stems from its renewability, biodegradability, versatility, and abundance in nature. However, native starches have limitations, including poor solubility, thermal instability, retrogradation, and susceptibility to enzymatic degradation. Despite the broad range of applications of starch, challenges persist in optimizing its modifications, addressing cost constraints, and ensuring regulatory compliance in food and pharmaceutical applications. These shortcomings necessitate modifications to enhance their physicochemical and functional properties. Additionally, recent trends indicate a shift towards bioengineered starches with enhanced functional properties, utilizing artificial intelligence for process optimization, and expanded applications in advanced biomaterials to achieve sustainable development goals. Thus, this review delves into the diverse sources of starch, highlighting extraction techniques and comparing their characteristics. Additionally, the review examines various modification strategies and discusses their effects on starch structure, gelation, and industrial applications. Recent advancements in dual-modification approaches, nanotechnology integration, and eco-friendly modification techniques have been examined in the context of sustainable development. Moreover, this review highlights the role of modified starch in various pharmaceutical applications, including drug delivery systems and bioadhesives, as well as its importance in biodegradable plastics, food packaging, wastewater treatment, and bioethanol production.
