    • 14:55 to 15:35
  • Venue:
    • Mellangatan 1, Visby, Sweden.

BONUS RETURN hosted a seminar at Almedalen – a yearly democratic gathering to discuss environmental and social issues in Sweden. The aim of the seminar was to discuss the possibilities of introducing promising innovative solutions in the Baltic Sea Region. The three innovations in BONUS RETURN: Aquacare, Ravita and TerraNova were presented and their potential, strengths and weaknesses discussed by needs owners from water companies, river basins and the agricultural sector.

Description of the social issue

Eutrophication continues to be a major concern in the Baltic Sea, while nutrients that cause eutrophication are needed as fertilizer in agriculture. Through circular system solutions, we can stay within the planetary boundaries of bio-geochemical flows of nitrogen and phosphorus.

BONUS RETURN is evaluating how circular solutions for nutrients and carbon can be introduced in the Baltic Sea Region to reduce eutrophication. In 2018, the project held an innovation competition seeking technologies in the EU with the potential to reuse nutrients and carbon. Three winners: Ravita (Finland), Aquacare (Netherlands) and TerraNova (Germany) were selected and are now part of the project’s pre-commercialisation phase.

The seminar was held in Swedish at the Vattenforum in Almedalen. Read the full programme.
