Nutrient losses from agriculture drive eutrophication in the BalticSea. To address this, the Baltic Sea Regional Nutrient RecyclingStrategy (BSR NRS) and the EU Strategy for the Baltic SeaRegion (EUSBSR) Policy Area (PA) Nutri provide a framework forminimizing nutrient losses and promoting circular nutrient use throughenhancing nutrient recycling. PA Nutri plays a key role in coordinatingregional cooperation and aligning policies to support transnationalnutrient management efforts.However, despite policy commitments, the transition to circularnutrient solutions faces significant challenges, including technological,economic and regulatory barriers. The CiNURGi project, funded by InterregBSR (#C049), directly supports BSR NRS and PA Nutri by addressingthese challenges through a cross sectoral approach, linking agriculture,municipal, and industrial nutrient recycling solutions to promote regionalcircular nutrient management. This article explores CiNURGi’s approach toaddressing these challenges to advance nutrient recycling in the BSR.
