CBA analysis of selected eco-technologies in the BSR

This report provides a cost-benefit analysis (CBA) of selected eco-technologies for wastewater treatment and nutrient recovery across three catchment areas in the Baltic Sea Region (BSR). By combining CBA with multi-criteria analysis (MCA), the study evaluates the economic efficiency of various technologies compared to baseline scenarios, focusing on the recovery of phosphorus and nitrogen and the mitigation of greenhouse gas emissions.

• Initial results indicate that most evaluated eco-technologies do not currently provide a positive net present value (NPV), as the benefits are generally too small to offset the required investments and operational costs.
• In the Vantaanjoki catchment area in Finland, anaerobic digestion is identified as the most promising alternative with an NPV of 67 million EUR, followed by thermal treatment with an NPV of 12 million EUR.
• The study utilizes a bottom-up CBA approach that integrates results from a multi-criteria analysis (MCA) to ensure stakeholder involvement in selecting eco-technologies and to create an initial ranking for decision-makers.
• The economic model assumes a project lifetime of 30 years and applies a social discount rate of 3.50%, with sensitivity analyses conducted at 0% and 30%.
