“…The water permeation improved from 51 L m −2 h −1 to 98 L m −2 h −1 , accompanied by a flux recovery ratio of around 80% and a rejection rate of roughly 96% (Figure 7a,b). Additionally, the onset degradation temperature saw an increase of around 30 • C, while the mechanical strength was strengthened by approximately 1.2 MPa [120]. Govindappa et al demonstrated the integration of recycled PVC material as a base polymer and benzalkonium chloride (BAC) as an extractant to develop low-cost polymer inclusion membranes for extracting arsenic from water [121].…”

Membrane technology has shown a promising role in combating water scarcity, a globally faced challenge. However, the disposal of end-of-life membrane modules is problematic as the current practices include incineration and landfills as their final fate. In addition, the increase in population and lifestyle advancement have significantly enhanced waste generation, thus overwhelming landfills and exacerbating environmental repercussions and resource scarcity. These practices are neither economically nor environmentally sustainable. Recycling membranes and utilizing recycled material for their manufacturing is seen as a potential approach to address the aforementioned challenges. Depending on physiochemical conditions, the end-of-life membrane could be reutilized for similar, upgraded, and downgraded operations, thus extending the membrane lifespan while mitigating the environmental impact that occurred due to their disposal and new membrane preparation for similar purposes. Likewise, using recycled waste such as polystyrene, polyethylene terephthalate, polyvinyl chloride, tire rubber, keratin, and cellulose and their derivates for fabricating the membranes can significantly enhance environmental sustainability. This study advocates for and supports the integration of sustainability concepts into membrane technology by presenting the research carried out in this area and rigorously assessing the achieved progress. The membranes’ recycling and their fabrication utilizing recycled waste materials are of special interest in this work. Furthermore, this study offers guidance for future research endeavors aimed at promoting environmental sustainability.

“…This is due to starch's low molecular weight and amorphous rather than fibrous structure. Similarly, films of carboxymethyl cellulose/starch reinforced with cellulose nanocrystals, fish gelatin films conjugated with carboxymethyl cellulose, and gum arabic films [43] have low mechanical properties. Polyhydroxybutyrate and vegetable fibre composites have also shown lower mechanical strength due to lower molecular weight [44].…”

“…Consequently, research is moving toward the development of new membrane filtration approaches based on the use of biopolymers or ecofriendly gel blend polymers [40][41][42][43]. Moreover, thanks to the knowledge of nanotechnology and molecular functionalization [44][45][46], it is possible to modulate the performance of these sustainable membranes that can lack in some aspects as mechanical properties and thermal and chemical resistance than the ones made from fossil-derived polymers [42,47].…”

Water quality and disposability are among the main challenges that governments and societies will outside during the next years due to their close relationship to population growth and urbanization and their direct influence on the environment and socio-economic development. Potable water suitable for human consumption is a key resource that, unfortunately, is strongly limited by anthropogenic pollution and climate change. In this regard, new groups of compounds, referred to as emerging contaminants, represent a risk to human health and living species; they have already been identified in water bodies as a result of increased industrialization. Pesticides, cosmetics, personal care products, pharmaceuticals, organic dyes, and other man-made chemicals indispensable for modern society are among the emerging pollutants of difficult remediation by traditional methods of wastewater treatment. However, the majority of the currently used waste management and remediation techniques require significant amounts of energy and chemicals, which can themselves be sources of secondary pollution. Therefore, this review reported newly advanced, efficient, and sustainable techniques and approaches for water purification. In particular, new advancements in sustainable membrane-based filtration technologies are discussed, together with their modification through a rational safe-by-design to modulate their hydrophilicity, porosity, surface characteristics, and adsorption performances. Thus, their preparation by the use of biopolymer-based gels is described, as well as their blending with functional cross-linkers or nanofillers or by advanced and innovative approaches, such as electrospinning.
