Converting used COVID-19 facemasks into green absorbents for carbon capture

The emergence of COVID-19 in early 2020 has led to an increase in medical waste, including used facemasks, which has become a new threat to public health and the environment. Despite being in a post-COVID-19 pandemic world, many countries are still mandating mask-wearing in public to reduce the spread of the virus. However, a large number of these masks, including single-use and multiple-use forms, are made from plastic materials that are long-lasting. As a result, millions of tons of waste have accumulated in landfills across several countries in a short period, posing a danger to the environment.
