Sheep wool could be the key to making seaweed farming plastic free, according to experts. Engineers from Queen’s University Belfast have been working on an innovative project for the last two years in a bid to drive forward sustainability in the industry.

A marine mystery that puzzled scientists for roughly 40 years has finally been solved. Researchers discovered an unknown seaweed species off the coast of Cornwall, England, and its identity turned out to be a tiny red species that hadn't been formally identified before.

Korean seaweed exports are hitting record highs, but there is limited evidence that the surge is consistently driving up domestic consumer prices, according to a new analysis.

Each year at beaches across Europe and Africa, thousands of brown seaweed clumps begin washing ashore towards the end of summer. But unlike the seaweed that usually lines the Mediterranean coast, these balls are often studded with hundreds of tiny, multicolored plastic fragments that they absorbed while at sea — from torn pieces of plastic bags to microscopic particles smaller than a strand of hair.

As part of the Horizon Europe project CIRCALGAE, researchers at Teagasc Pig Development Department investigated whether ingredients produced from seaweed processing can provide a sustainable alternative feed ingredient for use in pig diets.

In Paraty, Brazil, a Caiçara family has transformed seaweed cultivation into gastronomy, educational tourism and a source of income. The venture is driven by strong female participation and a deep connection to their territory.

University of Miami research is examining whether black soldier fly larvae can transform beached sargassum into a lower-carbon alternative for aquaculture feed. According to the university, the work aims to turn “an environmental burden into coastal value solution.” Julio Camperio, working in the Aquaculture Nutrition and Biotech Laboratory at the Rosenstiel School, is studying the larvae’s ability to bioconvert and bioremediate the seaweed waste.
