Summary
Scientists from the University of Bonn studied kitchen sponges and found they release microplastics during dishwashing. However, water usage during manual dishwashing has a larger environmental impact than the microplastics from sponges.
Key Facts
- Kitchen sponges can release microplastic particles when used.
- The study was conducted by researchers in Germany and included real-world household data.
- Different types of sponges released different amounts of microplastics, ranging from 0.68 to 4.21 grams per person annually.
- Water consumption during manual dishwashing significantly contributes to environmental damage, more than microplastic release.
- Using a dishwasher can be more water-efficient than washing dishes by hand.
- In Germany, widespread use of a specific sponge type could release up to 355 tonnes of microplastics yearly.
- Wastewater treatment plants catch most microplastics, but some still enter the environment.
