The BONUS RETURN project has been exploring how ecotechnologies can turn nutrients and carbon from being environmental problems, into benefits – by closing nutrient loops and promoting circularity. Results, conclusions and recommendations were presented at the final conference.

BONUS RETURN began on 1 May 2017 with partners from Sweden, Finland, Poland and Denmark and ends on 31 October 2020. The overall aim of BONUS RETURN was to improve the adaptation and adoption of agriculture and municipal wastewater ecotechnologies for capture and reuse of nutrients and carbon in the Baltic Sea Region.

Project / BONUS RETURN – reducing emissions by turning nutrients and carbon into benefits. The project focuses on turning waste into circular solutions for the Baltic Sea
SEI brief / This policy brief responds to the recent government inquiry into phosphorus recycling and the future of agricultural use of sewage sludge in Sweden.
Project / BONUS RETURN – reducing emissions by turning nutrients and carbon into benefits. The project focuses on turning waste into circular solutions for the Baltic Sea
Journal article / This open-access study argues that there is considerable potential to develop a circular economy in phosphorus, but policy support and new research is needed.
