The EU funded SEABASED project’s pilot moved from laboratory tests to practice, as a new marine restoration method, the spreading of activated limestone by, was tested in an enclosed sea bay in Rymättylä on Thursday 11th June.
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.
The SEABASED project’s activated limestone pilot was lifted up by the Swedish Kungliga Ingenjörsvetenskapsakademien (IVA) as one of the top 100 research initiatives that have business potential.
The SEABASED Steering Group and project team gathered in Mariehamn, Åland 24.–25.4.2019 to catch up with the pilots and to collect views and valuable advice.
The SEABASED project held a meeting in Gryts Varv, Valdemarsvik, Sweden 30.–31.1.2019.
The Finnish-Swedish joint project reviews new methods of marine protection, and pilots small-scale local measures that can reduce the nutrient load that is already in the sea as well as curb eutrophication on the coastlines of Finland, Åland and Sweden.
