Quintana Roo News – On July 25, 2025, the Quintana Roo sargassum processing center moved into its final phase. Oscar Rébora Aguilera, head of the State Ministry of Ecology and Environment (SEMA), confirmed that the first plant will stand in Cancún’s hotel zone. The facility will serve as a circular economy center, turning the state’s seasonal seaweed influx into sustainable products and green jobs.

The project builds on over 14 months of pilot tests and health‑focused studies. “Today we are ready to take the next step toward the industrialization of Sargassum, based on more than 14 months of work in a pilot plant along with studies supported by public health criteria,” said Rébora Aguilera. The feasibility of processing sargassum has been proven safe and efficient, a vital component in the Quintana Roo’s sargassum processing efforts.
A key pillar of the plan involves carbon credits. Authorities aim to certify sargassum collection as a greenhouse gas mitigation measure by preventing its natural decomposition on beaches. That would generate unissued CO₂ certificates for sale in voluntary or regulated markets. “It’s an issue we’ve invested a lot of money in, and more resources are needed because we don’t know how the following seasons will turn out,” he explained. He also stressed the need to verify fishery products when collecting at sea to protect marine ecosystems.
Exploring biogas production through biodigestion
Engineers plan to mix sargassum with organic waste and plant prunings to boost methane yield. They will also develop bioethanol trials, leveraging seaweed sugars. These efforts demonstrate the significance of sargassum processing in Quintana Roo’s renewable energy expansion.
The full scope covers monitoring, collection, transportation and treatment of sargassum. It includes installing three wastewater treatment plants within Cancún’s hotel zone and producing biomethane from its effluent. The center will showcase advanced water management technologies to minimize consumption and reuse treated water.
SEMA estimates more than 100 products can emerge from sargassum, though most need health‑sector certification. For now, the focus remains on scaling biogas and bioethanol lines. SEMA has already selected two sites in Cancún for the first plant. Once it goes online, this sargassum‑processing initiative will set a new standard for environmental innovation across the region.
Leaders expect the center to generate new green jobs, spur scientific research and deliver long‑term solutions to the sargassum challenge. By industrializing seaweed, Quintana Roo aims to protect its beaches, cut emissions and foster a resilient coastal economy.
