Melamine sponges shed microplastics when scrubbed and landfills burp PFAS
Summary
Researchers found that melamine sponges shed poly(melamine-formaldehyde) microplastic fibers during abrasive cleaning use, with global estimates suggesting these products could release over one trillion microplastic fibers per month. The study also reports on research showing that landfill leachate releases PFAS compounds, highlighting multiple sources of emerging contaminant release from common consumer and waste management contexts.
If you own a pair of white shoes or have ever tried to remove crayon from a wall, you’re probably thankful for melamine sponges. These products practically erase tough stains and scuffs through their unique abrasiveness and without additional cleaning products. But the American Chemical Society (ACS) reports on June 20, 2024, that these “magic” sponges shed microplastic fibers when worn down. Because researchers publishing in ACS’ Environmental Science & Technology have reported in their article “Mechanochemical Formation of Poly(melamine-formaldehyde) Microplastic Fibers During Abrasion of Cleaning Sponges” that, worldwide, melamine sponges could release over a trillion microplastic fibers every month.
