The invasion of Sargassum represent a public health problem and impact of tourist activity on the island
So a solution is being studied for the treatment of the pollution generated by these algae: anaerobic digestion of Sargassum algae, which could be a sustainable and economically viable solution. The biological process of anaerobic digestion makes it possible to recycle organic materials – agricultural co-products, food processing, and sewage sludge, as well as seaweed Sargassum – producing biogas and digestate used as natural fertilizer. Thus, at the request of Sy.MEG, Evergaz, through its research Ledjo Energy conducted a feasibility study on energy recovery from organic waste and Sargassum algae in Guadeloupe.
A pilot project to test the transformation sargassum into renewable energy
The study showed that the benefits of such a project would be multiple: – A solution for processing sewage sludge, and local agricultural and organic waste while avoiding the emission of almost 5,320 tons of CO2;- The production of more than 6 GWh of renewable electricity;- The production of natural fertilizer for agriculture Guadeloupe (digestate);- The creation of local jobs, direct and indirect. The next step is the establishment of a pilot project to test for one year the biogas process and verify the quantities of Sargassum can be treated each year in the biogas plant.
