Sargassum

From eyesore to asset: How a smelly seaweed could fuel cars

When large swathes of invasive seaweed started washing up on Caribbean
beaches in 2011, local residents were perplexed.

Soon, mounds of unsightly sargassum - carried by currents from the
Sargasso Sea and linked to climate change - were carpeting the
region's prized coastlines, repelling holidaymakers with the pungent
stench emitted as it rots.

Precisely how to tackle it was a dilemma of unprecedented proportions
for the tiny tourism-reliant islands with limited resources.

In 2018, Barbados' Prime Minister Mia Mottley declared sargassum a
national emergency.

Now, a pioneering group of Caribbean scientists and environmentalists
hope to turn the tide on the problem by transforming the troublesome
algae into a lucrative biofuel.
