Baltic Sea Science Congress

Sustainability analysis of scenarios for circular systems for nutrients and carbon

  • Date & Time:
    • August 22, 2019
    • 17:00 to 19:00
  • Venue:

    Aula Magna floor 5, Stockholm University

BONUS RETURN will participate at the 12th Baltic Sea Science Congress. The event gathers the marine research community for discussions on the last 10 years of Baltic Sea research and how it has adopted new interdisciplinary approaches and scientific disciplines. Policy aspects of the latest research will also be discussed.

POSTER SESSION 5: Policy and Management/Assessment Strategies

Sustainability analysis of scenarios for circular systems for nutrients and carbon

Presented by Erik Kärrman, RISE – Research Institutes of Sweden

Description

Circular systems for handling wastewater and agricultural wastes is a way forward to decrease the fluxes of nutrients to the Baltic Sea. This session will showcase how BONUS RETURN is aiming to develop new policies, decision support systems and new innovations to implement circular systems for nutrients and carbon in the Baltic Sea. In one part, the project has used sustainability analysis to evaluate different scenarios for applying circular systems for agricultural waste and wastewater in three catchment areas: Fyrisån (Sweden), Vantaanjoki (Finland) and Slupia (Poland). Composting, anaerobic digestion, pyrolysis, source separation systems, leaching of phosphorus from ashes and ammonia stripping are examples of new technologies that have been evaluated.

Studies show that there are many promising innovations for reducing the fluxes to the Baltic Sea but are not ready for market yet, and they must also perform on other sustainability criteria such as the emission of greenhouse gases, costs and local economy. Another finding is that new policies are needed to promote the market for recycled nutrient products as fertilizers on agriculture.
