The city of Thônex recently hosted teams of ambassadors from the Swiss competence center against littering, IGSU, as part of a local awareness campaign designed to combat public waste. Using a combination of chalk, mobile carts, and humor, the ambassadors engaged with residents to promote proper waste disposal and recycling practices.
The intervention took place on May 22 and 23 near the Place de Graveson, a central location in the city. Activities included the “StreetUnArt” campaign, where ambassadors used chalk to draw animal silhouettes around abandoned litter, and collaborative workshops where local youth created posters for an upcoming waste awareness week in September.
Did You Know? The “Grande étude suisse sur le littering” has found that individual awareness discussions can be effective, with data indicating a 27% reduction in littering following such interactions.
Expert Insight: The integration of creative, non-confrontational tactics like “StreetUnArt” suggests a shift toward psychological nudging rather than traditional enforcement. By engaging citizens in public spaces, these programs aim to create a lasting social norm around cleanliness, potentially reducing the financial and environmental burden of waste management for municipalities.
Context and Significance
The collaboration highlights a broader trend in Swiss waste management, where municipalities are increasingly partnering with specialized organizations to address seasonal spikes in littering. Summer months often see higher rates of waste accumulation in public areas, making proactive outreach a key strategy for local authorities.
The initiative also serves as a precursor to Thônex’s annual waste valorization week, scheduled for September 14 to 20, 2026. This period of awareness will conclude with an “Urban Plogging” event on September 20, where residents participate in a city-wide cleanup.
Future Outlook
The ongoing efforts are part of a larger national research project conducted by IGSU in partnership with the Haute école de psychologie appliquée FHNW. While the 2025 phase of this study focused on picnic and leisure areas, the 2026 research is expected to examine the effectiveness of anti-littering measures in restaurant zones near take-away outlets. Future phases, planned for 2027, will likely extend this research to interurban routes, potentially shaping how Swiss cities manage littering policies in the coming years.
