22 Eco-Schools participated in the Litter Less Campaign, engaging 12,639 students and 428 teachers across 13 cities. The campaign addressed a wide range of waste-related topics, including recycling, composting, soil health, and reducing invisible pollutants. Schools made active use of Litter Less resources such as lesson plans, curricular frameworks, and waste monitoring guidelines.
A highlight of the campaign was a week-long environmental action programme at the Regional High School “El Salto & Juanacatlán Module”, where daily themes included zero single-use plastics, zero disposable packaging, zero food waste, creative reuse, and composting. The initiative also involved mapping litter hotspots, organizing clean-ups, and fostering a culture of environmental responsibility through “Tequios” (collective community work).
In total, schools collected 19,032 kg of waste, produced 1,073 kg of compost, and participated in 9 webinars and 160 hours of training. While collaboration with Mars Wrigley representatives has yet to be established nationally, the campaign in Mexico demonstrates strong grassroots engagement and growing environmental literacy among students and educators.
