“…RC has been prominently studied for its unique properties, such as biodegradability and remarkable mechanical and thermal properties [ 173 , 174 ]. Certain essential properties have to be taken into consideration for the application of RC as a mulching film, such as its mechanical properties and tensile strength to avoid fracture in its structure [ 175 , 176 ]. Apart from that, the membrane’s thermal stability is also important to ensure the prolonged thermal degradation caused by molecular deterioration.…”

“…Cellulose-based black mulch film (BMF) was fabricated, and its effect on the soil temperature and yield was studied. It was reported that the BMF depicted the least variance in the soil temperature, which was attributed to the smaller light transmittance and solar radiation [ 176 , 179 ]. They further elaborated that a suitable temperature is essential to enhance the growth of plants.…”

Cellulose is one of the most abundant natural polymers with excellent biocompatibility, non-toxicity, flexibility, and renewable source. Regenerated cellulose (RC) products result from the dissolution-regeneration process risen from solvent and anti-solvent reagents, respectively. The regeneration process changes the cellulose chain conformation from cellulose I to cellulose II, leads the structure to have more amorphous regions with improved crystallinity, and inclines towards extensive modification on the RC products such as hydrogel, aerogel, cryogel, xerogel, fibers, membrane, and thin film. Recently, RC products are accentuated to be used in the agriculture field to develop future sustainable agriculture as alternatives to conventional agriculture systems. However, different solvent types and production techniques have great influences on the end properties of RC products. Besides, the fabrication of RC products from solely RC lacks excellent mechanical characteristics. Thus, the flexibility of RC has allowed it to be homogenously blended with other materials to enhance the final products’ properties. This review will summarize the properties and preparation of potential RC-based products that reflect its application to replace soil the plantation medium, govern the release of the fertilizer, provide protection on crops and act as biosensors.

In the EU, sheep bred for dairy and meat purposes are of low quality, their economic value is not even enough to cover shearing costs, and their wool is generally seen as a useless by-product of sheep farming, resulting in large illegal disposal or landfilling. In order to minimize environmental and health-related problems considering elemental compositions of discarded materials such as waste wool, there is a need to recycle and reuse waste materials to develop sustainable innovative technologies and transformation processes to achieve sustainable manufacturing. This study aims to examine the application of waste wool in biocomposite production with the help of a sustainable hydrolysis process without any chemicals and binding material. The impact of superheated water hydrolysis and mixing hydrolyzed wool fibers with kraft pulp on the performance of biocomposite was investigated and characterized using SEM, FTIR, tensile strength, DSC, TGA, and soil burial testing in comparison with 100% kraft pulp biocomposite. The superheated water hydrolysis process increases the hydrophilicity and homogeneity and contributes to increasing the speed of biodegradation. The biocomposite is entirely self-supporting, provides primary nutrients for soil nourishment, and is observed to be completely biodegradable when buried in the soil within 90 days. Among temperatures tested for superheated water hydrolysis of raw wool, 150 °C seems to be the most appropriate for the biocomposite preparation regarding physicochemical properties of wool and suitability for wool mixing with cellulose. The combination of a sustainable hydrolysis process and the use of waste wool in manufacturing an eco-friendly, biodegradable paper/biocomposite will open new potential opportunities for the utilization of waste wool in agricultural and packaging applications and minimize environmental impact.

“…The industrial revolution has brought packaging materials to develop within the areas of edible, biodegradable, nanocomposite, active and intelligent packaging. [1][2][3][4][5] Flexible film packaging types describe any type of materials which is not rigid, but the term "flexible polymer" is often reserved for nonfibrous plastic polymers which are composed of molecular chains have long sequences of one or more species of atoms or groups of atoms linked to each other. [6,7] Poly(vinyl alcohol) (PVA) is a synthetic polymer carries the predictable properties of hydrophilic, biodegradable, tasteless, odorless, good mechanical properties and high ability to form packaging films.…”

In this study, mulberry (Morus nigra sp.) leaves extract (MN) was used as a structure modifier and antimicrobial agent in poly(vinyl alcohol) (PVA) blend films. We prepared PVA/MN blend films by solution casting at various concentrations. The SEM micrographs showed that PVA_MN75 has a smooth and continuous cross-sectional morphology with better compatibility. Fourier-transform infrared spectroscopy results suggest that a specific concentration of MN in PVA films facilitates a physical interaction that improves mechanical and thermal properties. The tensile strength of the films increased from 1.886 MPa to 2.907 MPa after adding mulberry leaf extract. Furthermore, the films were assessed for their solubility in water (12.116-15.833 %), absorption (9.800-21.610 %), and moisture content (6.530-14.257), which further demonstrates that blend films exhibit lower water solubility. Moreover, the soil burial biodegradation test indicates that PVA/MN film biodegradability is strongly affected by its MN concentration. Upon soil burial, all films showed an increase in biodegradability of 29% as burial time has prolonged in both soil and compost for thirty seven (37) days. Enhanced antibacterial activity has been observed in the PVA/MN film-forming solution and can be considered a promising substitute for polluting plastic packaging.
