SpongeBot v1.0.0 Release
AI summary Read the abstract
Researchers released SpongeBot v1.0.0, an open-source automated test stand used to measure microplastic release from kitchen sponges, with construction manuals, CAD files, and wiring diagrams made freely available to support reproducible research on household microplastic emissions.
This is the construction manual of the SpongeBot v1.0.0 test stand as published in Hamann, L., Galafton, C., Rühr, P. T., Blanke, A., & Thonemann, N. (2026): From sink to Sea: Microplastic release from kitchen sponges and potential environmental effects. Environmental Advances 23: 100693. DOI: 10.1016/j.envadv.2026.100693. For a construction and wiring manual, please follow the instrucitons in the PDF file (SpongeBot_v1_0_0.pdf). This is a static release. Up-to-date CAD files, wiring diagram, and instructions video are avilable at Thingiverse. Up-to-date code to run the machines is available at GitHub.

Measuring the Effects of Microplastics on Sponges
AI summary Read the abstract
Researchers investigated how microplastics affect marine sponges, which are important filter feeders in coastal ecosystems, noting that very little research had examined sponge-microplastic interactions. The study aimed to fill a knowledge gap about microplastic impacts on a key group of benthic organisms that filter large volumes of seawater.
Automatization of multistep sample preparation for microplastics monitoring in aquatic environments
AI summary Read the abstract
Scientists built a machine that automatically cleans water samples to detect tiny plastic particles, cutting out slow manual lab work. Tests showed it reliably captured 97 to 100% of microplastics without contaminating samples, making it easier to track plastic pollution in rivers and lakes, an important step toward understanding how much of this plastic ends up in our water supply.

From sink to Sea: Microplastic release from kitchen sponges and potential environmental effects
AI summary Read the abstract
Kitchen sponges were found to release between 0.68 and 4.21 grams of microplastics per person per year into wastewater through abrasion during dishwashing, with sponges containing less plastic causing significantly less environmental damage. This is important for microplastic pollution research as it quantifies a previously undercharacterized household source of microplastic emissions and demonstrates that material choice in everyday items directly impacts pollution levels.
