“…A super hydrophilic (antifogging) coating was prepared by mixing tannic acid and pectin aqueous solutions in a fixed volume ratio according to the previously published work. 29 First, we prepared a tannic acid (3 wt %) solution in distilled water, and an aqueous solution of pectin (3 wt %) was also prepared using the same method. After getting well-homogenized solutions, they were mixed in a 1:1 ratio until they turn into a sticky and viscous liquid.…”

The utilization of solar energy to make human lives better has been one of the primary and green approaches adopted by ordinary people and researchers for decades. This approach has recently gained a lot of attention as a way to tackle clean water scarcity in remote areas. Costly components, complex manufacturing procedures with rarely available equipment, and a surface to condense water vapors are challenges in the way of its application in the required areas. Here, we propose a complete system to solve this problem with a handmade light absorber and a superhydrophilic surface (antifogging) to get vapors back to collect clean water. Our handmade flower-like light absorber stitched by crochet work, the single stitch method, was able to get a decent evaporation rate of 1.75 kg/m 2 ·h in pure water and slightly lower rates of 1.62 and 1.65 kg/m 2 ·h with brine and pond water, respectively. Still, our proposed superhydrophilic coated surface can collect ∼37% more water than the pristine surface. This system has a huge potential for use in rural areas because of multiple key advantages, such as simple technology, readily available low-cost raw materials, and easy fabrication.

“…Due to the exponential increase in the consumption of plastic and poly(ethylene terephthalate) (PET), 1–3 waste PET has accumulated rapidly in the environment and is causing huge environmental pollution and resource wastes. 4–6 Great efforts have been devoted to finding efficient recycling methods for PET waste, where chemical recycling is considered as the promising and sustainable solution for PET degradation, 7–9 including hydrolysis, 10,11 aminolysis, 12–14 and glycolysis.…”

“…In addition, enriched active sites on the polymer matrix endow its high potential to adsorb the pollutant and increase the contact with the photocatalyst and thus enhance the photocatalytic activity. The hydrophilicity of these polymers is also playing another role in preventing the fouling of the composite surface (Zhang et al 2019;Jiang et al 2020;Huang et al 2021). Coupling of green photocatalysts with bio-based polymers can provide a sustainable strategy in integrating photodegradation of pollutants and antifouling behavior.…”

The last decade has been witnessing overwhelming efforts to achieve social sustainability from mitigating the health and environmental effects to innovative new strategies for sustainable energy production. Those efforts have been devoted to exploiting sustainable materials for handling energy shortage and environmental deterioration to fulfill the Sustainable Development Goals (SDGs). In this article, we engage in those efforts and shed new light on sustainable models applicable to water, air, and solid management from the practical standpoint of SDGs. The first sustainable model is a combination between renewable resources and sustainable materials for the fabrication of biomass/photocatalysts hybrid composites. The green hybrid photocatalysts can be synthesized by electrospinning or 3D techniques. These geometric bio-hybrid photocatalysts are the backbone of the next photocatalytic house model. These houses can significantly participate in the mitigation of climate change via CO 2 capture and conversion to renewable energy and fuels. Furthermore, it anticipates that these photocatalytic houses are capable of participating in the alleviation of acid rain through converting toxic gasses such as nitrogen oxide (NO x ) and sulfur oxide (SO x ) into sustainable products. On the other hand, some suggestions have been raised to face and control microplastic pollution and one of these suggestions is introducing artificial intelligence such as tracer-based sorting as a sustainable strategy solution to enhance the plastic circular economy. The last model relies on optimizing the utilization of Jatropha in the landfill post-closure area toward integrated solid waste management and alternative biofuel production. These models will pave new ways of realizing sustainability.
