Call Circular economy - Development & Innovation projects

Purpose and goal

The proposed Project will form a model for circular economy to reduce oxygen depletion in the anoxic basins of the Baltic sea, w here the internal leakage of phosphorus is large. The method implies that top sediment layers w ill be retrieved from the basins, reducing oxygen depletion. The retrieved sediment volumes yield three components; energy, nutrients and silt constituting a monetary value and a base for ecological compensation. Ecological compensation will facilitate for industries to compensate for unhandled emissions of nitrogen and phosphorus. The project focuses on silt.

Expected results and effects

By creating a circular economy, primarily on Swedish territorial waters, a possible role model will be set for other countries in the Baltic region and globally. The new solutions would possibly be exported to other continents with similar challenges, for example Chesapeake Bay in the USA. There are also a number of business policy aspects for Sweden and the Baltics. By continuously decreasing the internal leakage of phosphorus, there will be increasing opportunities for the tourist industry around the Baltic Sea, yielding new job opportunities for women and youth.
