Face Masks to Combat Coronavirus (COVID-19)—Processing, Roles, Requirements, Efficacy, Risk and Sustainability
This review examines the materials, manufacturing methods, and effectiveness of face masks used during the COVID-19 pandemic, most of which are made from non-biodegradable plastics like polypropylene and polyester. Researchers found that while masks are effective at reducing virus transmission, their widespread use and improper disposal have created a significant environmental concern as they break down into microplastics. The study calls for more sustainable mask materials and better waste management strategies to reduce the environmental footprint of pandemic-related plastic waste.
A comprehensive review on antimicrobial face masks: an emerging weapon in fighting pandemics
This review examines the development of antimicrobial face masks designed to fight pandemics, including coatings that can neutralize viruses and bacteria on contact. While these advanced masks offer improved protection, the study also raises concerns about microplastic fibers and chemical additives that may be released during use, adding to environmental and health concerns.
Nanotechnology-enabled face masks: Balancing protection and pollution in aquatic environments
This review examined the dual role of nanotechnology-enhanced face masks in providing antimicrobial protection while also releasing micro- and nanoplastics into aquatic environments when improperly disposed. The authors call for better mask design standards and disposal strategies to balance protective benefits against environmental pollution.
Nanotechnology-Enhanced Face Masks: Future Scopes and Perspectives
This review assessed nanotechnology-based approaches for creating reusable face masks, motivated by the massive single-use mask waste generated during the COVID-19 pandemic. Nano-enhanced masks with antimicrobial and self-cleaning properties were identified as a promising path toward reducing both environmental contamination and pathogen transmission.

A Novel Face Masks and it’s Utility during COVID-19 Pandemic: A Comprehensive Review
This review examines the technical specifications, materials, and engineering advances of face masks used during the COVID-19 pandemic, including both commercial and homemade options. Researchers discuss the environmental impact of disposable masks, noting that their widespread use has contributed to microplastic pollution as mask materials degrade. The study highlights the need for mask designs that balance effective viral protection with reduced environmental contamination.
Antiviral/antibacterial biodegradable cellulose nonwovens as environmentally friendly and bioprotective materials with potential to minimize microplastic pollution
Biodegradable cellulose nonwoven materials incorporating antiviral and antibacterial agents were developed as a sustainable alternative to polypropylene face masks, demonstrating comparable filtration performance with significantly faster environmental degradation, reducing the microplastic pollution burden of disposable PPE.
Face masks: a COVID-19 protector or environmental contaminant?
This review examined how the massive global use of disposable face masks during COVID-19 has created a significant source of microplastic pollution, with billions of masks entering the environment and releasing plastic fibers and chemical contaminants.
Microplastics/nanoplastics released from facemasks as contaminants of emerging concern
This review examines how disposable facemasks, made primarily from polypropylene and polyethylene, release microplastics and nanoplastics into the environment. Chemical, physical, and biological processes break down discarded masks into tiny plastic particles that persist in ecosystems. Given the billions of masks used during COVID-19, this represents a significant and growing source of microplastic pollution.
A review of disposable facemasks during the COVID-19 pandemic: A focus on microplastics release
This review examines the environmental threats posed by disposable face masks used during the COVID-19 pandemic, with a focus on microplastic release. Researchers found that discarded masks undergo physical and chemical degradation in the environment, generating microplastics that contaminate both aquatic and terrestrial ecosystems. The study provides an overview of current knowledge on microplastic extraction methods and proposes strategies for controlling mask-related plastic pollution through source reduction and improved waste management.
Single-use surgical face masks, as a potential source of microplastics: Do they act as pollutant carriers?
Researchers investigated whether single-use surgical face masks, widely used during the COVID-19 pandemic, are a potential source of microplastic fibers released into the environment. The study found that used masks entering uncontrolled waste streams can shed fibrous microplastics.
Face mask structure, degradation, and interaction with marine biota: A review
Single-use face masks, which surged in use during COVID-19, are a significant source of microplastic pollution because they degrade into tiny plastic fragments and also serve as rafts for harmful bacteria, pathogens including SARS-CoV-2, and antibiotic resistance genes in aquatic environments. This review underscores that the environmental and public health costs of mask disposal extend well beyond simple litter, carrying risks for water quality and the spread of antimicrobial resistance.
Understanding the environmental impacts of facemasks: a review on the facemask industry and existing life cycle assessment studies
This review examined the environmental life cycle impacts of disposable face masks during the COVID-19 pandemic, finding that the surge in mask production and disposal created a significant new source of plastic waste and microplastic pollution globally.
From Protection to Pollution: The Impact of Mask Use on Micro(nano)plastic Release
This bibliographic review found that global mask consumption during COVID-19 reached as high as 2.5 trillion single-use masks per month, with Asia as the largest consumer, and documented how improper mask disposal releases microplastics and nanoplastics into terrestrial and aquatic environments.
Addressing the worldwide shortages of face masks

Uncovering the Release of Micro/nanoplastics from Disposable Face Masks at Times of COVID-19
Researchers found that disposable face masks release significant amounts of micro- and nanoplastic particles when subjected to water exposure and mechanical stress similar to environmental conditions. This confirms that the massive use of masks during COVID-19 introduced new sources of microplastic pollution into the environment.
Fabric structure and polymer composition as key contributors to micro(nano)plastic contamination in face masks.
Researchers investigated how the structure of face masks — including surgical polypropylene and fashionable polyurethane masks — influences the generation of micro- and nano-plastics during normal wear and UV aging.
