sargassum

What will Mexico do with all that sargassum?

Due to climate change and nutrification of coastal environments, algal blooms are becoming more frequent and exaggerated. Algal blooms are typically in reference to microalgae, however, there can be blooms of macroalgae as well. For example, right now over 100 million tons of Sargassum are headed to the Mexican shores. For many coastal industries, this is a big problem, harbors become blocked and resort beaches become deserted. That’s why President López Obrador is bringing out the big guns, the Mexican Navy. The help is coming after an outcry of resorts failing to keep the beaches clear. The Cancún-Puerto Morelos hotels association has estimated that cleaning the beaches of sargassum will cost at least 700 million pesos (US $36.7 million) this year.

It’s unclear what the Navy has planned for 100 million tons of seaweed, our guess is to throw it all in a landfill. One thing is clear, any entrepreneurs that figure out how to make that seaweed into a revenue stream will become extremely wealthy. Hotel chains are already willing to pay millions for someone to take it away. There is opportunity for production of, fertilizers, nutraceuticals, protein, or cosmetics.
