“…One of the significant drawbacks of PVC-based products, which can have a negative impact on the environment, is their long lifespan and inability to biodegrade, so the issue of waste disposal of PVC is quite urgent [ 28 , 29 , 30 , 31 , 32 , 33 ]. Waste disposal by burning is also not a solution for this problem due to the pollution released into the atmosphere that is harmful to the environment and humans [ 34 , 35 , 36 , 37 ].…”

To enhance the ecological properties of polyvinyl chloride (PVC) products, the fabrication of PVC-based composites using biofillers with acceptable performance characteristics could be considered. In this work, plant-filled PVC-based composite materials were fabricated and their optical, structural, thermal, and mechanical properties, depending on the nature of the filler, were studied. Spruce flour, birch flour, and rice husk were used as fillers. Optical measurements showed the selected technological parameters, allowing films with a uniform distribution of dispersed plant filler in the polymer matrix to be obtained. Using the plant fillers in PVC films leads to a reduction in strength characteristics; for instance, the tensile strength changed from 18.0 MPa (for pure PVC film) to ~7 MPa (for composites with 20 wt.% of fillers), and to ~5–6.2 MPa (for composites with 40 wt.% of fillers). Thermal investigations showed that the samples with plant fillers could be used at low temperatures without changing their operating characteristics. Thus, plant-filled PVC-based composite materials have a wide operating temperature range, from—65 °C to 150 °C. TGA analysis has demonstrated that the rice husk affected the thermal stability of the composites by increasing their thermal decomposition resistance. The ability to absorb water was observed during the investigation of water absorption of the samples. And the highest degree of water absorption (up to 160 mg/g) was detected for the sample with 40 wt.% of rice husk. In general, plant-filled polymer composites based on PVC can be used on an equal basis with unfilled PVC plastic compounds for some applications such as in construction (for example, for design tasks).

The abundance of plants as a renewable bioresource has captured the significant attention of researchers, driving them to explore new biodegradable polymeric materials. However, there are still many biobased materials with untapped potential, offering opportunities to synthesize novel biodegradable polymers with multifunctional properties. This work provides a unique solvent and catalyst‐free melt polycondensation process to prepare a series of polyesters using zingerol (Zing‐OH), a reduced form of zingerone, as a primary component for the first time. Briefly, Zing‐OH (a ginger‐based component) is employed in conjunction with a variety of renewable resources, such as citric acid (CA), sebacic acid (SA), and xylitol (Xy), to synthesize multifunctional soft tissue‐like ZCSX polyesters. Fourier‐transform infrared (FTIR) and 1H‐nuclear magnetic resonance (NMR) spectroscopy are used to validate the synthesis of the polyesters, while thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and universal testing machine (UTM) are employed to investigate their physicochemical properties. Moreover, the synthesized polyester's thermal, mechanical, and biodegradation properties can be fine‐tuned by simply varying the Zing‐OH feed ratio. The mechanical properties of the synthesized polymer resemble various human tissues, including the liver, uterus, bladder, breast, and temporal and nasal cartilage. This suggests that the synthesized polyesters can potentially be useful in tissue engineering applications. Furthermore, the polyester demonstrated exceptional recovery responses and good shape memory behavior at ambient body temperature. Additionally, as observed from Alamar blue, live/dead assays, and time‐dependent in vitro wound images, the synthesized polyester demonstrated antibacterial activity, good in vitro cytocompatibility, cell proliferation, and wound healing capabilities against mouse fibroblast cells (NIH/3T3). The developed biocompatible polyester also exhibits excellent hemocompatibility for human blood, indicating its potential use in the field of regenerative medicine.

Myco degradation is an effective technique for breaking down waste plant substances made of lignin, cellulose, and hemicellulose, which are collectively known as lignocellulose. This abundant organic material is found throughout the world. Due to its recalcitrant nature, lignocellulose poses a challenge for efficient conversion into biofuels, biochemicals, and other valuable products. Myco degradation, which involves the use of fungi to degrade lignocellulosic materials, offers a sustainable and cost‐efficient resolution to this challenge. This review provides an overview of the mechanisms and applications of myco degradation for lignocellulosic biomass degradation. The review discusses the various types of fungi involved in lignocellulose degradation, their enzymatic systems, and the factors that influences their performance. Furthermore, the potential applications of myco degradation products, such as biofuels, enzymes, and bioplastics, are reviewed. It also highlights the implications of myco degradation for waste management and sustainable development. Overall, myco degradation represents a promising technology for the efficient deprivation of lignocellulosic waste biomass, and further research in this field holds great potential for the sustainable creation of bio‐based products.This article is protected by copyright.
