From an ecological nuisance to a valuable resource, Caribbean scientists are developing a sustainable biofuel from invasive sargassum seaweed that threatens local tourism and health.

Turning the Tide: Caribbean Scientists Transform Invasive Seaweed into Biofuel
Caribbean researchers innovate by converting sargassum into bio-compressed natural gas for vehicles.
Over the past decade, the Caribbean has faced the growing challenge of sargassum, a smelly seaweed linked to climate change that washes ashore in large quantities, disrupting coastal tourism and impacting marine life. At the forefront of addressing this environmental crisis, a group of innovative scientists and environmentalists at the University of the West Indies (UWI) in Barbados have found a way to transform this invasive seaweed into a renewable energy source, specifically bio-compressed natural gas for vehicles.
This unexpected solution emerged after Barbados Prime Minister Mia Mottley declared a national emergency regarding the sargassum problem in 2018. With limited resources, local communities struggled to manage the unsightly seaweed that was overwhelming their beaches. Dr. Legena Henry, a renewable energy expert at UWI, led a team that was initially focused on using sugarcane for biofuel production. However, upon realizing the abundance and availability of sargassum, they pivoted their research. With the help of her student Brittney McKenzie, they began experimenting with a blend of sargassum, wastewater from rum distilleries, and local sheep dung to produce biogas.
Their groundbreaking project gained attention at the 2019 UN General Assembly, where they showcased the potential of this biofuel. The team secured funding to further their research and conducted successful tests with a biogas-powered Nissan Leaf. This innovative technology not only provides an alternative energy source but also mitigates the environmental risks posed by sargassum, a culprit in declining tourism and health hazards.
Biologist Shamika Spencer, another key member of the project, explained the broader implications of repurposing waste, emphasizing the importance of the initiative in protecting beaches and marine ecosystems. As the team gears up for a pilot program aimed at demonstrating the feasibility of their biogas solution, they are optimistic about the potential for larger-scale production, which could significantly impact the region's energy sustainability.
This project stands as a testament to the Caribbean's effort to harness local resources and address climate change challenges. With plans to establish a biogas station and the intent to explore other sargassum-derived innovations, the collaborative work of these scientists illustrates a proactive approach to environmental resilience. As Dr. Henry articulated, this successful endeavor not only benefits the Caribbean but could also serve as a model for other regions grappling with similar ecological dilemmas posed by invasive species.
