Overview

• More than 120 institutions joined a Baixada Santista megamutirão across eight cities, with waste slated for detailed classification to feed a scientific database.
• About 500 volunteers removed 300 kg of debris from Rio’s Flamengo Beach, with Comlurb responsible for subsequent collection and proper disposal.
• In Ubatuba, roughly 400 participants cleared 168 kg of trash from Perequê-Açu and gathered nearly 4,000 cigarette butts, including 78 kg of recyclables.
• During the WSL event in Imbituba (SC), volunteers logged items and collected 31 kg of litter in 20 minutes, with contaminated material destined for landfill.
• Organizers reported plastic as the dominant pollutant, aligning with a USP/Sea Shepherd study showing 91% of beach litter is single-use plastic, while Botafogo and Leblon actions added education and the ‘Mar de ideias’ award.
