“…It is hypothesized that the chloride in [Bmim]Cl has a major impact on the dissociation of hydrogen bonds in cellulose. Nevertheless, [Bmim]Cl is very poisonous and crystallizes at ambient temperature (Khaw et al, 2019). Alternately, 1-Butyl-3-methylimidazolium acetate ([Bmim][OAc]) has been deemed beneficial in lignocellulosic biomass swelling, and its lignin solubility is not as impacted by water as [Bmim]Cl's (Gogoi and Hazarika, 2019).…”

IntroductionA significant population growth and development in industrialization has led to the concurrent expansion in many sectors including agricultural activities and daily consumption (Zhang et al, 2022). Numerous everyday activities and industrial operations create garbage, and the amount of waste generated rises proportionately to the demand for goods (Sebastian and Louis, 2021). As a result, the issues related to resource management and garbage disposal are rapidly increasing. In addition to posing serious environmental risks, poor disposal and handling can have a detrimental effect on human health (Mrozik www.resrecov.com HIGHLIGHTS ➢ This review discusses recycling solid waste into watertreatment membranes. ➢ Circular economy solid wastes can be utilized to make membranes. ➢ Suitable biopolymers, plastics, and inorganics waste for membranes is introduced. ➢ Membrane fabrication and performance with recycled materials are discussed. ➢ Future perspectives on waste-derived membranes are suggested.

Nanocellulose, which is biodegradable and possesses excellent physicochemical properties, has high potential in many applications. However, its intrinsic hydrophilic nature makes it difficult to be used as fillers in most hydrophobic polymer composites. Here, cellulose nanocrystals (CNCs) were successfully prepared using 1‐hexly‐3‐methylimidazolium hydrogen sulfate [Hmim][HSO4] ionic liquid under optimized conditions at 71°C, ultra‐sonication amplitude of 69%, and ultrasonication time of 23 min. The prepared CNCs were surface‐modified using 1‐butyl‐3‐methylimidazolium tetrafluoroborate [Bmim][BF4]. A 3D printable nanocomposite filament containing CNCs embedded in polylactic acid was fabricated via extrusion process at 170°C. The prepared filaments were characterized using universal testing machine, field emission scanning electron microscopy, thermogravimetric analysis, and FTIR. It was shown that CNCs had a diameter and length of 10–24 and 60–400 nm, respectively. It was also found that incorporating 2 wt% of CNCs into the matrix phase increased filaments tensile strength by 2.5% (from 54.59 to 57.35 MPa) due to the plasticization effect of [Bmim][BF4]. The prepared composites exhibited lower activation energies compared to neat PLA due to the small traces of sulfate group on F‐CNC. The mechanical attributes of CNCs/PLA nanocomposites were retained at values comparable to that of fresh PLA and were demonstrated to be 3D printable.

“…Firstly, this might be related with the number of microvoids on the surface of the composites which would facilitate the water transfer [48][49][50], as verified by the SEM graphs. Next, the interactions between lipid phase and biopolymer chains in o/w emulsion films might just increase the external tortuousness and take negligible effect on the moisture barrier of emulsified films [51][52][53][54].…”

Preparation and Characterization of Starch/Empty Fruit Bunch-Based Bioplastic Composites Reinforced with Epoxidized Oils

et al. 2020

This study examined the development of starch/oil palm empty fruit bunch-based bioplastic composites reinforced with either epoxidized palm oil (EPO) or epoxidized soybean oil (ESO), at various concentrations, in order to improve the mechanical and water-resistance properties of the bio-composites. The SEM micrographs showed that low content (0.75 wt%) of epoxidized oils (EOs), especially ESO, improved the compatibility of the composites, while high content (3 wt%) of EO induced many voids. The melting temperature of the composites was increased by the incorporation of both EOs. Thermal stability of the bioplastics was increased by the introduction of ESO. Low contents of EO led to a huge enhancement of tensile strength, while higher contents of EO showed a negative effect, due to the phase separation. The tensile strength increased from 0.83 MPa of the control sample to 3.92 and 5.42 MPa for the composites with 1.5 wt% EPO and 0.75 wt% ESO, respectively. EOs reduced the composites’ water uptake and solubility but increased the water vapor permeability. Overall, the reinforcing effect of ESO was better than EPO. These results suggested that both EOs can be utilized as modifiers to prepare starch/empty-fruit-bunch-based bioplastic composites with enhanced properties.
