Air pollution adversely affects human health and the environment. according to the who, more than 99% of world population resides in the region where the air pollution exceeds the who air quality guidelines. long term exposure to polluted air increases the risk of heart attacks, asthma, stroke, and lung cancer. indoor air pollution significantly impacts human health and the environment. women and children suffer the greatest health burden due to the use of inefficient combustion technologies and polluted fuels, as they are mostly responsible for household chores. therefore, air filtration is important for a healthy and prosperous household. there are various challenges associated with existing air filters, such as high capital, maintenance and operating costs, end-of-use disposal of exhausted non-biodegradable air filters, limited filtration efficiency, noise generation, and energy consumption. moreover, exhausted filters create solid waste management challenges, eventually ending up in landfills, thus increasing the carbon footprints. therefore, it is imperative to explore low cost, regenerable and biodegradable filter media that can be used multiple times upon exhaustion and biodegraded eventually. nanofiber-based air filters can be an alternative of the above reported problems because of their high specific surface area, low pressure drop, and can be fabricated with biodegradable material with several tuneable surface properties. we aim to develop a sustainable approach for synthesis of novel biodegradable electrospun nanofibers (ens) as air filters from food waste materials and offering a closed loop circular solution. this strategy can offer a two-pronged solution to the solid waste problem as it can (i) minimize the food waste by utilizing them as a pre-cursor material for the air filter and (ii) eliminate the end-of-life fabric filter disposal issue by replacing them with biodegradable filters, thus overall reducing the carbon footprints and making the air filtration product eco-friendly and cost effective. in this study, we have developed eco-friendly, low-cost, biodegradable air filters from raw banana peel waste blended with polyvinyl alcohol (biocompatible, biodegradable, cost-effective, non-toxic and water-soluble polymer) using a simple, versatile, fast, and cost-effective electrospinning technique typically used to fabricate nanoscale fibers from polymeric solutions. electrospun nanofibers possess a high surface area to volume ratio, small pore size, tunable property, higher uptake capacity and are densely packed, and have interconnected pores. therefore, an efficient air exchange across the nanofibers at low-pressure drop and higher probability of removing pms. moreover, it is the first study where the exhausted air filters (bpe/pva) have been regenerated and reused in multiple cycles, thus enhancing the air filter's sustainable production, reducing the net carbon emission, and contributing to sustainable development goals (sdgs). during biomass extraction from the banana peel waste, the left-over material was used as soil ameliorant and has been successfully tested for soil moisture retention capabilities. this has led to the development of a materially closed-loop and sustainable process for bpe/pva nanofibers fabrication. this study aims to develop bio-based, sustainable nanofiber filters with regeneration and reuse potential and investigate the impact of food-waste material on nanofibers’ diameter, tensile strength, hydrophobicity, and effective surface area. the variation in the en properties was examined and correlated with the solution properties such as conductivity, viscosity, and surface tension. moreover, the study evaluated pressure drop over time and filtration efficiency across various nanofibrous filters.
