BONUS RETURN Final Conference presentations
On 8th September 2020 at the project’s final conference, results, conclusions and recommendations on how ecotechnologies can turn nutrients and carbon from environmental problems into circular solutions in the Baltic Sea Region were presented.

The project highlights evidence on circular innovations for reducing eutrophication in the Baltic Sea. Key recommendations include:

  • Stronger policy steering for nutrient reuse management is needed.
  • Technologies for recycling nutrients in the Baltic Sea exist and are ready for market but better data on hotspots and most effective combination of ecotechnologies is needed.
  • We need to shift mindsets and regulations to reduce-reuse-recycle and strengthen interactions between wastewater and agriculture.
  • Procurement and innovative business plans can bridge the gap between innovation and implementation.

The conference was moderated by Arno Rosemarin, senior research fellow at Stockholm Environment Institute and senior expert in the BONUS RETURN project.

Welcome & Introduction

By Karina Barquet, Stockholm Environment Institute

BONUS RETURN project coordinator, Karina Barquet, highlighted the project objectives and gave an overview of the results to be presented.

Review of ecotechnologies for circulating nutrients and carbon

By Biljana Macura, Stockholm Environment Institute

A presentation on the review of ecotechnologies for circulating nutrients and carbon in agriculture and wastewater sectors, based on knowledge gaps addressed through systematic evidence synthesis.

Sustainability analyses in three catchment areas

By Erik Kärrman, RISE Research Institutes of Sweden & Søren Marcus Pedersen, University of Copenhagen

A presentation on the multi-criteria analysis and cost-benefit analysis carried out on the project’s three case studies: Fyrisån in Sweden, Vantaanjoki in Finland and Slupia in Poland.

Modelling efficiency of ecotechnologies in Vantaanjoki, Slupia and Fyrisån

By Jari Koskiaho, Finnish Environment Institute & Tomasz Okruszko, Warsaw University of Life Sciences

SWAT modelling results of the impact of ecotechnologies on nutrient levels in the three river basins: vantaanjoki, fyrisån and slupia.
Circular innovations in the Baltic Sea Region

By Sten Stenbeck, RISE Research Institutes of Sweden

A presentation on the pre-commercialization support given to the three innovations in the project: Ravita, Finland, TerraNova, Germany and Aquacare, Netherlands.

Barriers and opportunities for closing the nutrient loop

By Linn Järnberg and Nelson Ekane, Stockholm Environment Institute

A presentation on policy, governance, market and technical aspects of accelerating the transition towards a circular phosphorus economy. A report on perceptions of sewage sludge application in agricultural lands in Sweden, was also presented.

Success stories of circular ecotechnologies in the Baltic Sea Region

Presented by Mark Rasmussen, SEI. Followed by a Q&A with case study leads: Olle Olsson, SEI, Marek Giełczewski, WULS and Jari Koskiaho, SYKE.

Playing to learn: Serious Game System

By Steven Bachelder, Uppsala University

A presentation of the Serious Game System including a showcase of the digital game developed in the project, MONITOR ECO TECH.

Conclusions & Recommendations

By Karina Barquet, Stockholm Environment Institute

A summary of the achievements in BONUS RETURN as well as future policy directions and research gaps.

In December 2017, BONUS RETURN held a competition to search for emerging ecotechnologies with the potential to capture and reuse nutrients and/or carbon in the Baltic Sea region. The three selected winners, RAVITA from Finland, TerraNova from Germany and Aquacare from Netherlands, received pre-commercialization support in the project.

In the short videos below, they explain briefly what their innovations are, the support received in BONUS RETURN and highlight challenges and opportunities for applying their innovations in the Baltic Sea region.

Video recordings of the three innovations in BONUS RETURN

Marc Buttmann, TerraNova, Germany

The TerraNova® Ultra technology converts waste sludge into two products: bio-coal and phosphorus. The technology also increases the biogas production in a wastewater treatment plant and reduces the amount of disposable waste.

Kati Blomberg, RAVITA, Finland

The RAVITA process recovers phosphorus and nitrogen directly from  wastewater and reject water. The phosphoric acid and ammonium phosphate products can be fed into the fertilizer cycle or other industrial uses.

Prashanth Kumar, Aquacare, Netherlands

Aquacare’s BioPhree technology is designed to reduce phosphorus to very low concentrations, which is necessary to prevent harmful algal bloom. The phosphorus is recovered in a form that can be used as a fertilizer.
