New APB paper out: Can Sargassum become a resource instead of a problem?

Large amounts of Sargassum seaweeds have become a growing problem for many coastal regions. When it washes ashore, it can harm ecosystems, affect tourism, and create high clean-up costs for local communities.

A new scientific paper, developed with contributions from partners in the AlgaeProBANOS project, looks at a different approach: can Sargassum be used as a resource instead of being treated as waste?

The study explores how Sargassum biomass could be turned into bio-based products (such as fertilisers or other materials) or used for bioenergy production. Both options have potential, but the paper shows that there is no single solution that works everywhere. Higher-value products can be more sustainable, but only if the biomass is of good quality and proper processing systems are in place. Bioenergy options are often more flexible and may be easier to apply where infrastructure or markets are limited.

An important message from the paper is that local conditions matter. Successful use of Sargassum depends on factors such as collection methods, regulations, environmental safeguards, and local needs.

Overall, the study highlights that with the right strategies, Sargassum could support the blue bioeconomy, helping reduce waste, create value, and support coastal communities, while protecting the environment.
