What happens to our used COVID masks?


The COVID-19 pandemic has caused a lot of changes in our daily lives, and one of them is the use of face masks. Wearing masks has become a crucial aspect of preventing the spread of the virus. However, as millions of people continue to use masks, one question that comes to mind is what happens to all our used COVID masks? In this post, we will discuss the fate of used COVID masks.

The Environmental Impact of Discarded Masks

The massive use of masks has led to a significant increase in waste. Most used masks are disposable, meaning they add to the already-existing solid waste problem. If not handled correctly, discarded masks can cause environmental pollution. Discarded masks can end up in landfills, oceans, and other water bodies, causing harm to wildlife and marine life. The masks can also take years to decompose, which means they will remain a significant environmental hazard for a long time.

In fact, according to a report by the conservation group OceansAsia, an estimated 1.5 billion disposable masks were discarded in the ocean in 2020 alone. These masks, made primarily of plastic, take hundreds of years to decompose, releasing harmful chemicals into the environment and posing a threat to marine wildlife. In addition, discarded masks can also become entangled in marine life, making it difficult for them to swim and breathe.

Recycling and Reuse of Masks

While most masks are disposable, some are made to be reusable. Reusable masks can be washed and worn again, reducing waste. However, most people prefer disposable masks due to their convenience. Nevertheless, several recycling initiatives have started to recycle used masks. These programs involve disinfecting the masks and melting them down to create new products like plastic benches, paving stones, and other plastic products.

One such initiative is the Mask 2 Mask project by TerraCycle, a global waste management company. The project aims to collect used masks and recycle them into new ones, reducing waste and preventing environmental pollution. Another example is the Canadian company GreenMantra, which has developed a process to convert used masks into a sustainable plastic additive that can be used in various products.

Proper Disposal of Used Masks

Proper disposal of used masks is essential in preventing the spread of COVID and environmental pollution. Used masks should be disposed of in a closed bin and not thrown on the ground. If you are using a reusable mask, make sure to wash it after each use. It is also crucial to follow local guidelines on the disposal of used masks. Most municipalities have clear guidelines on how to dispose of masks.

In addition, there are some steps you can take to reduce the waste generated by masks. For example, you can opt for reusable masks instead of disposable ones, or choose masks made from sustainable materials like bamboo. You can also consider donating your used masks to organizations that collect and distribute them to those in need, such as homeless shelters or schools.


The use of masks has become a crucial aspect of our daily lives as we navigate through the COVID-19 pandemic. However, the massive use of masks has led to an increase in waste, which can cause environmental pollution. We can reduce the impact of used masks on the environment by properly disposing of them or using reusable masks. Recycling initiatives have also started to recycle used masks, which is a step in the right direction. As we continue to use masks, let us be mindful of their environmental impact and play our part in reducing waste.
