Sustainability technologies for resource recovery in the Baltic Sea

The study employs multi-criteria analysis and stakeholder workshops to evaluate resource recovery systems in the Fyriså river catchment (Sweden) and Słupia river catchment (Poland). While the technical systems were similar across both sites, the preferred alternatives differed: source-separation was preferred in Fyris, while a large redesign with ammonia stripping was preferred in Słupia. In both cases, the most expensive systems achieved the highest sustainability scores, suggesting significant potential benefits from enhanced resource recovery despite higher costs.

• The preferred technical system for resource recovery varied by location: in the Fyriså river catchment, source-separation was the preferred alternative, whereas in the Słupia river catchment, a large redesign of wastewater treatment followed by ammonia stripping of the reject water was preferred.
• In both the Swedish and Polish case studies, the systems with the highest costs were rated as the most sustainable, highlighting the potential benefits of improving resource recovery from domestic wastewater.
• Stakeholders involved in the assessment did not prioritize technical performance over other sustainability criteria, contrasting with the general trend in resource recovery research which focuses primarily on technical aspects.
