Science in and with society: insights into synthetic microfibre emissions from textiles with citizen scientists
Summary
Researchers partnered with citizen scientists to study synthetic microfibre emissions from washing textiles at scale, generating broad real-world datasets on how washing conditions and fabric properties drive microfibre release and assessing public attitudes toward adopting microfibre reduction behaviors.
The release of synthetic microfibers during washing of textiles is a major contributor to the emissions of microplastics to the environment. However, mechanisms driving microfibre emissions are poorly understood and little is known about the willingness of individuals to adopt pollution-reducing measures. Existing studies on the impact of textile properties or washing conditions on microfibre release are limited by non-realistic laboratory set-ups or case-by-case assessments and do not include behavioral dimensions. Here we present in-situ research on washing practices and related microfibre release through citizen science, which allows for fine-grained data collection in real-life settings. Different microfibre collection methods, ranging from washing bags and washing machine filters to stickers (for data collection with children) were tested and employed in collaboration with citizen scientists across the Netherlands. In addition to the microfibres, participants reported data on textile characteristics, washing conditions, behaviors, and pro-environmental attitudes. The outcomes of a first extended pilot study with 100 participants yielded insights into total amounts and characteristics of microfibres released under different washing conditions and for different clothing items; but also on the impact of participation in such a data collection on citizens' views on microplastic pollution and their perceived agency in implementing pollution reducing measures.

Science in and with society: insights into synthetic microfibre emissions from textiles with citizen scientists
Researchers engaged citizen scientists in a large-scale study of synthetic microfibre emissions from household textile washing, collecting real-world data on how fabric properties and washing conditions influence microfibre release rates while also investigating individual willingness to adopt pollution-reducing laundry practices.
Psychological outcomes from a citizen science study on microplastics from household clothes washing
A citizen science study in which households measured synthetic microfibers released during laundry washing found that participants reported increased environmental concern and behavioral intent to reduce microfiber emissions, demonstrating that participatory research on household microplastic sources can have positive psychological effects.
Psychological outcomes from a citizen science study on microplastics from household clothes washing
Researchers conducted a pre-registered three-month citizen science study in the Netherlands where participants used microfiber-capturing laundry bags and completed pre/post surveys on environmental concern, perceived responsibility, and washing behavior. High baseline environmental concern was found but did not strongly predict behavior change, suggesting psychological interventions beyond awareness are needed to reduce laundry microfiber emissions.
Psychological outcomes from a citizen science study on microplastics from household clothes washing
A three-month citizen science project in the Netherlands studied how participating in microfiber laundry bag monitoring influenced residents' environmental awareness and washing behaviors, finding that hands-on engagement with pollution measurement can shift consumer attitudes.
REMEDIES Citizen Science Protocol for the Recovery and Quantification of Microplastics
This citizen science protocol equips everyday volunteers to collect and quantify microplastic fibers released from synthetic fabrics during home laundering. Standardizing community-based sampling methods is critical for scaling up environmental monitoring and building the large datasets needed to understand how washing clothes contributes to microplastic pollution.
