Reed is a sustainable but underutilized material that, when harvested, can contribute to a cleaner and healthier Baltic Sea. Commonly found along the Baltic Sea's coasts, reed plays an important role in the nutrient cycle. Besides creating habitats for fish, birds, and insects, reed absorbs nutrients that otherwise lead to the eutrophication of the Baltic Sea. By harvesting reed, nitrogen and phosphorus are removed from the water and can instead be beneficial on land, for instance as nutrient-rich material for cultivation, animal feed filler, and packaging material. Axfoundation is testing several uses for harvested reed.
