Scientists have conducted an experiment to determine how effective insects can be in eating and degrading plastic, specifically focusing on microplastics smaller than 5 millimeters. The study used mealworms (Tenebrio molitor) to test their ability to consume plastic from disposable COVID-era face masks.
It would take 100 mealworms approximately 138 days or about 4.5 months to eat just one disposable face mask. Microplastics smaller than 5 millimeters are especially worrisome, as they have been linked to higher risks of heart attacks and strokes.
The researchers turned to the iconic, rectangular, tissue-y face masks made using classic polypropylene or plant-based plastic polylactic acid. They melted the mask plastic and abused it into microbits, mixing in wheat bran for a more realistic dining experience.
While this study provides valuable insights into the limitations of using insects to combat plastic pollution, it also highlights the need for a more sustainable approach. The researchers suggest that instead of relying on insects to clean up microplastics, we should focus on reducing our use of plastic altogether.
