Sustainability technologies for resource recovery in the Baltic Sea

This research paper evaluates three technical systems for recovering nutrients and carbon from domestic wastewater in Sweden and Poland using multi-criteria analysis and stakeholder participation.

• The study utilized multi-criteria analysis and participatory workshops with local stakeholders to determine sustainability scores for three technical systems compared to a baseline in the Fyriså river catchment (Sweden) and the Słupia river catchment (Poland).
• Sustainability preferences differed by location: in the Fyriså catchment, source-separation was the preferred alternative while phosphorus extraction from incinerated sludge was the least sustainable; in the Słupia catchment, a large redesign of wastewater treatment with ammonia stripping of reject water was preferred, while source-separation scored lowest.
• In both case studies, the systems with higher costs achieved the highest sustainability scores, suggesting significant potential benefits from improved resource recovery. Additionally, stakeholders did not prioritize technical aspects over other sustainability criteria, contrasting with the typical focus of resource recovery research.
