Integrating the Use of Biopolymers in the Facemask Technology Towards Plastic Waste Reduction

Background: Recently, personal protective equipment (mainly masks) increased due to the COVID-19 pandemic. The raw materials used for the facemasks production are non-biodegradable synthetic polymers. Objective: Therefore, their discharge on the streets, in public areas, and seawater generates dangerous effects on the environment (flora and fauna) and human health. Methods: Their degradation occurs under the action of ultraviolet radiation, heat intensity, and mechanical stress by producing fragments and microplastics that have detrimental effects on marine fauna and human health (via the relative's food chain). Conclusion and recommendation: This review describes the dangerous effect of the facemasks on the environment (marine and soil) and on human health. In addition, some essential approaches for reducing pollution, such as the PPP disinfection and the use of biopolymers in personal protective equipment (PPEs) technology, have been intensely discussed.
