    Nordkalk donates limestone to the SEABASED-project

    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.

    Pike factories reduce the adverse effects of eutrophication

    As one of the measures in the SEABASED project to help control eutrophication, a pike factory, i.e., an artificial small-scale wetland suitable as a breeding area for pike, will be created in the Linköping area in Sweden. Marine biologist Miina Mäki, the Project Manager for the SEABASED project, describes how the pike factories work and why they are important.

    Sweet results after a salty summer

    In one of the SEABASED pilots nutrient-rich bottom waters are removed from two eutrophied semi-closed, coastal bays and the possibility of recycling nutrients by utilizing the water for irrigation on fields is tested. Annica Brink, a project coordinator from The Government of Åland, reveals the first results from two irrigated fields.

    A field excursion to the cement factory in Slite, Gotland

    When in Gotland, it is hard not to talk about limestone and the local Cementa factory. The factory was originally built 100 years ago in 1919 and now employs around 230 in Slite. The SEABASED project team and steering group visited the factory to learn more not only about the making of Cementa’s products but also about the sorbent, that is used in our pilot, which is treated in this factory. This sorbent is produced from marl and is used to bind phosphorus to the sediment in pilot sites in Sweden and Finland.
