Common cleaning sponge found to release trillions of microplastic fibers

That “magic” sponge under your sink may be hiding an environmental downside. While melamine sponges are famous for effortlessly scrubbing away stubborn stains, they slowly break down as you use them—shedding tiny plastic fibers that wash into water systems. Researchers estimate that globally, these sponges could release over a trillion microplastic fibers every month, potentially entering the food chain and affecting wildlife.
