Danish project seeks to upcycle fish farming waste into fibre and umami-rich algae for food sector

Over the next four years, the SeaFree project will develop a closed, sustainable cycle on land that utilizes residual nutrients and CO2 from shrimp and fish farming – which otherwise pollute the sea and contribute to global warming – to grow high-value seaweed for the food and healthcare industries. “The project aims to use seaweed production to absorb and convert emissions from land-based aquaculture into a high-value product​,”​ said Professor Marianne Thomsen from the Department of Food Science at the University of Copenhagen. “​Among other things, the seaweed will be used for dietary supplements that can prevent diabetes and sustainable foodstuffs innovations. In addition to capturing emissions that would have otherwise been emitted into the atmosphere and aquatic environment, the seaweed produced is both healthy and rich in umami flavour​.​”​ The project, funded by Innovation Fund Denmark with DKK 14.4 million (€1.9m), is being carried out in a collaboration among the ...
