A study from the University of Bonn reveals that kitchen sponges shed microplastics during dishwashing, with emissions ranging from 0.68 to 4.21 grams per person annually. However, the primary environmental impact stems from water consumption, accounting for 85-97% of the total damage.
- 01Kitchen sponges release microplastics as they wear down, with emissions varying by sponge type.
- 02Annual microplastic emissions per person can reach up to 4.21 grams, with significant increases if widely used.
- 0385-97% of the environmental impact of dishwashing is due to water consumption, not microplastic release.
- 04Consumers can reduce their environmental footprint by using less water and choosing sponges with lower plastic content.
- 05The study involved collaboration between the University of Bonn, Fraunhofer Institute, and Leiden University.

A recent study by researchers at the University of Bonn highlights that kitchen sponges, commonly used in households, release microplastics during dishwashing. The study found that sponges shed between 0.68 grams to 4.21 grams of microplastics per person annually, depending on the type of sponge. While this may seem minor, the cumulative effect across millions of households could lead to significant environmental pollution, potentially releasing 355 tonnes of microplastics annually in Germany alone. However, the study revealed that the major contributor to environmental damage during manual dishwashing is water consumption, which accounts for 85-97% of the total impact. To mitigate this, consumers are advised to use less water, select sponges with lower plastic content, and extend the lifespan of their sponges. The findings were published in the journal Environmental Advances and involved collaboration with several research institutions.
