Barbados and other Caribbean countries are being urged not to miss out on opportunities to produce fertilisers and animal feed additives from the sargassum seaweed that has inundated beaches.Urging the region not to let the massive amounts of sargassum go to waste, founder of the Guernsey-based The Seaweed Food Co. Ben Tustin said more research should be done to determine how the algae could be used to help boost food security.“I am not suggesting seaweed is a single solution to the world food crisis or climate issues at all, but it’s a massive part of it and people don’t seem to be aware of it,” he said on Friday during a session on Building Climate Resilience Through Food Security at the Virtual Island Summit 2022.Tustin, whose two-year-old company collects seaweed and uses it to produce seasonings and skincare products, said he was surprised more use was not being made of the natural resource that many countries had “literally sitting on their doorstep”.
