What You'll Learn
Masks made from plastic
The environmental impact of plastic masks can be significant. When discarded masks break down, they can release micro-sized plastic particles, contributing to water and soil pollution and ultimately affecting wildlife and humans. Studies suggest that humanity goes through approximately 129 billion face masks each month, leading to concerns about the proper disposal of the plastics contained within them.
To address this issue, researchers from the Aragon Health Research Institute and other institutions have developed a new material to replace polypropylene in surgical masks. This material, made from polyethylene terephthalate (PET) obtained from recycled plastic bottles, bags, and other discarded plastic products, can be used to create filter media with varying levels of filtering efficiency. By embracing recycled plastics and developing innovative solutions, we can reduce the environmental impact of masks made from plastic.
Some companies have also started offering expandable masks made from recycled plastic, which can flex and adjust to the wearer's face. These masks often feature a filter pocket for PM2.5 carbon filters and a removable nose wire for a secure fit. Additionally, companies like Petit Pli are embracing sustainability and slow-fashion values by using recycled fabrics and limited-quantity research projects to avoid overproduction and resource waste.

Masks as a source of plastic pollution
The use of face masks has been a fundamental prevention and control measure to limit the spread of COVID-19. However, the extensive use and improper disposal of single-use face masks are raising serious concerns for their environmental impact, particularly regarding plastic water pollution.
Face masks are made from a combination of absorbent fabrics, polyester, and common plastics such as polypropylene or polystyrene. These plastic components can break down into microplastics, which are tiny plastic particles under 5mm in length. Microplastics can enter water sources and the soil, eventually working their way into animals and humans. The ingestion of microplastics has been linked to potential health risks, including cardiovascular diseases and cancer.
Studies have found that a single face mask can release thousands of microplastic fibres and up to 10^11^ submicrometre particles when exposed to water, with most particles in the nano-sized domain. This suggests that face masks could be a significant source of microplastic pollution, especially considering the high consumption rate of 129 billion face masks per month globally.
The environmental impact of face masks as a source of plastic pollution is not yet fully understood, and further research is needed to assess the risks comprehensively. However, it is clear that improper disposal of face masks can contribute to plastic pollution, and steps should be taken to mitigate this issue. Some suggested solutions include promoting the use of reusable cloth masks, developing biodegradable masks, designating special disposal areas for masks, and standardizing waste processing procedures.
While the benefits of face masks in preventing the spread of COVID-19 are undeniable, it is important to address the potential side effects of their disposal on the environment. By implementing measures to reduce plastic pollution from face masks, we can help protect wildlife and human health while continuing to prioritize public health and safety.

Cloth masks as an alternative to plastic masks
The COVID-19 pandemic has seen a huge increase in the use of disposable plastic masks, with an estimated 129 billion masks being used globally per month. The majority of these are likely to be ending up in landfill, causing plastic pollution. The environmental impact of this is currently unknown, but studies suggest that plastic masks break down into microplastics faster than bulk plastics, and that these microplastics can enter the water and soil, eventually working their way into animals and humans.
As a result, there has been a push to encourage people to switch from disposable plastic masks to reusable cloth masks. Cloth masks have the advantage of being washable, reducing waste, and are also better at covering the nose and mouth than plastic face shields. Cloth masks are also better than nothing, as they trap larger respiratory droplets and limit the spread of the virus.
However, cloth masks are less effective at filtering out virus-carrying aerosols than FFP2 masks, which are typically three times more efficient at filtering larger particles than the best three-layered cloth masks. FFP2 masks filter at least 94% of 0.3-micron particles, whereas cloth masks are not intended to block these ultra-fine particles.
While the environmental impact of disposable plastic masks is a concern, it is important to note that the benefits of face masks in preventing the spread of COVID-19 are beyond debate. Cloth masks, in particular, have been recommended by the CDC as a primary way of protecting yourself and others against COVID-19.

Health risks associated with plastic in masks
The use of face masks has skyrocketed due to the COVID-19 pandemic, with an estimated consumption of 129 billion face masks per month. Many of these masks are made from plastics such as polypropylene or polystyrene, and their improper disposal has led to plastic pollution. While the environmental impact of plastic waste is evident, the health risks associated with plastic in masks are less clear-cut.
Microplastics in Masks
Microplastics are tiny particles of plastic, often defined as anything under 5mm in length. They can be found in various consumer products, from face and body scrubs to packaging and straws. The presence of microplastics in masks, particularly disposable ones, has raised concerns about potential health hazards.
Studies have shown that microplastics can be ingested or inhaled, leading to their presence in human feces and even the placenta. While the health effects of microplastics are still being studied, they have been linked to various health issues. Some potential risks include respiratory disease, metabolic function disruption, and endocrine system disruption. Additionally, exposure to microplastics may be linked to cardiovascular diseases and an increased risk of heart attacks, strokes, and death.
The impact of microplastics from masks specifically has not been extensively studied, but it is possible that they contribute to the overall microplastic pollution in the environment. Some experts suggest that the health risks associated with microplastics in masks are lower compared to the risks of contracting COVID-19.
Plastic Fumes
Inhaling plastic fumes, often occurring during burning or industrial processes, poses more immediate health risks. Plastic fumes contain toxic substances, including dioxins, phthalates, and volatile organic compounds (VOCs). These fumes can lead to respiratory damage and adverse effects on the immune and reproductive systems. Certain groups, such as children, the elderly, and individuals with pre-existing respiratory or immune conditions, are more susceptible to the harmful effects of plastic fume inhalation.
To mitigate the health risks associated with plastic in masks, it is recommended to switch from disposable plastic masks to reusable cloth ones. Proper waste processing procedures and designated disposal areas for masks can also help reduce the environmental and potential health impacts of plastic in masks.
