Nordkalk donates limestone to the SEABASED-project for piloting a measure that could bind eutrophying phosphorus permanently into the sediments of the seabed. In the project, three pilots at selected areas with activated limestone application to phosphorus containing bottom sediments will be implemented in chosen pilot sites in coastal bays in Sweden (Östergötland and Stockholm) and Finland (Archipelago Sea). The crushed limestone will be pre-treated by burning at facilities of Cementa in Gotland and then transported to the pilot sites and spread over the seabed to bind phosphorus into the sediment.
