Overview
- The federal government and Quintana Roo confirmed Thursday a reinforced strategy that includes 2,000 million MXN in two stages, with 768.7 million MXN in 2026 to raise sea collection to about 1,870 tonnes per day.
- Semar has expanded its fleet and barrier network and will add two remolcadores, six coastal sargaceros and roughly 50 km of coastal containment while preparing further capacity increases to reach about 4,000 tonnes per day in 2027.
- Authorities say the move aims to intercept sargassum at sea to prevent beach landings, with state monitoring centers using imagery from 10 ESA satellites to track patches across more than 140 beaches.
- Officials warn of health and environmental harms from decomposing sargassum — hydrogen sulfide and ammonia exposure, oxygen drops that can kill fish, and respiratory and skin irritation among workers and residents.
- The plan pairs cleanup with circular‑economy goals by funding treatment and industrial uses such as biogas, biofertilizers and bioplastics, and Cancún will host an international Global Gateway summit on sargassum on Oct. 1–2 to push regional coordination.
