Mexico's 2-Billion-Peso Sargassum Plan Puts Puerto Morelos at the Center

The federal government just made its biggest move yet against sargassum, and Puerto Morelos is not just on the list of places to protect. It has been chosen as the home base for turning the seaweed into something useful.

The Scale of the Problem

2026 is expected to be a severe sargassum season on Mexico's Caribbean coast, according to state environmental authorities. Mexico has committed 2 billion pesos to its Sargassum Action Plan through 2026, targeting the tourism-dependent state of Quintana Roo.

State authorities have projected that sargassum arrivals could exceed last year's levels, with collection figures already above 99,000 tons this season.

What the Money Buys

Secretary of the Navy Raymundo Morales Ángeles explained that the 2 billion peso investment will be divided into two stages to acquire two tugboats, six specialized coastal vessels, more dynamic barriers and additional collection equipment.

The first phase focuses on five key destinations: Cancún, Puerto Morelos, Playa del Carmen, Tulum and Mahahual. The funding will finance specialized vessels, offshore barriers, and monitoring systems to intercept sargassum at sea before it reaches beaches. The plan is intended to significantly increase offshore interception and daily collection capacity.

Do not expect an overnight fix. New boats and barriers require procurement, construction, delivery and trained crews. The government has not published firm delivery dates for the new equipment.

Puerto Morelos: Already Holding Its Own

Puerto Morelos has seen less sargassum than many other parts of the coast, helped by its reef, barriers and cleanup efforts. The municipality sits in front of the Puerto Morelos Reef National Park, part of the Mesoamerican Reef system, and the reef may help reduce the amount of sargassum reaching the shore.

Mayor Blanca Merari noted that Puerto Morelos has 2.3 kilometers of sargassum barrier and the protection provided by the reef, which help significantly reduce sargassum's arrival on the beaches. In coordination with various agencies, permanent monitoring, containment and cleaning efforts are maintained through specialized brigades.

The Navy is supporting cleanup in Puerto Morelos with vessels, barrier-cleaning boats and personnel assigned to sargassum removal. Officials reported that several thousand tons of sargassum were collected in Puerto Morelos during the first five months of 2026.

Puerto Morelos Becomes the Sargassum Hub

Here is the bigger story. The state government has designated Puerto Morelos for a circular-economy development project intended to support sargassum processing. The site is intended to bring together private companies, researchers and public-sector partners to process sargassum into marketable products.

The state and federal governments are also advancing a circular-economy center for sargassum processing, though the project timeline remains subject to development. Products being targeted include biogas, biofertilizer, bioplastics, construction materials and biodegradable packaging.

A federal initiative known as Caribe Circular has set a target of converting up to 2 million tons of sargassum into useful materials by 2028 and potentially creating 3,500 jobs. That is a development target, not a guarantee.

What It Means for Residents and Visitors

Some hotels in affected areas have reported higher cleanup costs and have adjusted pricing or operating plans in response to sargassum. One estimate has suggested that severe sargassum could reduce GDP in affected coastal areas by up to 11%.

Puerto Morelos has experienced less sargassum than some other parts of the coast, helped by the reef, the barriers and coordinated cleanup efforts. The new federal investment should strengthen that effort.

But residents should expect a gradual improvement, not an instant one, as new equipment arrives and the circular-economy development project takes shape right here in town.
