COVID-19 facemasks & marine plastic pollution.


Our oceans will be flooded with an estimated 1.56 billion face masks in 2020 says a report released today by Hong-Kong-based marine conservation organization OceansAsia. This will result in an additional 4,680 to 6,240 metric tonnes of marine plastic pollution, says the report, entitled “Masks on the Beach: The Impact of COVID-19 on Marine Plastic Pollution.” These masks will take as long as 450 years to break down, slowly turning into micro plastics while negatively impacting marine wildlife and ecosystems.

The report used a global production estimate of 52 billion masks being manufactured in 2020, a conservative loss rate of 3%, and the average weight of 3 to 4 grams for a single-use polypropylene surgical face mask to arrive at the estimate.

“The 1.56 billion face masks that will likely enter our oceans in 2020 are just the tip of the iceberg,” says Dr. Teale Phelps Bondaroff, Director of Research for OceansAsia, and lead author of the report. “The 4,680 to 6,240 metric tonnes of face masks are just a small fraction of the estimated 8 to 12 million metric tonnes of plastic that enter our oceans each year.”
